•Pore size and N content of ZIF8-based carbon can be controlled using PSM.•Samples exhibiting excellent methanol adsorption performance were prepared.•Targeted adsorption of methanol ...and toluene was achieved synergistically.•A solvent recycling process for 50–2000 ppm waste VOCs was proposed.
Methanol is a typical polar volatile organic compound that has been commonly used as a solvent in industrial processes and is considered as an important resource. It often appears with aromatic compounds in practical application scenarios. Conducting methanol and aromatic compounds recycle technology can provide us with a sustainable carbon source for fuels and materials well beyond the fleeting fossil fuel era. Post-synthesis modification (PSM) has been utilized to incorporate 3-amino-1,2,4-triazole (Atz) into ZIF-8, thereby enabling the derivation of mesopore structure and enhancement of nitrogen content in ZIF-8 derived carbon. With this method the obtained carbon exhibited a highly polarizable micro-mesoporous structure, resulting in high adsorption capacity for methanol adsorption at low concentrations. The experimental results showed that the VOCs adsorption on porous carbon is primarily dictated by its microporous structure at high pressure, and predominantly governed by the presence of nitrogen functional groups and the micro-mesoporous properties at low pressure. DFT theoretical analysis also showed that nitrogen functional group can improve the absorption capacity of methanol by adsorbents through changing the electron distribution and surface polarity of carbon-based materials. Finally, based on the emission properties that is low concentration and high volume of VOCs waste gas in industrial application, ZIF8-24-700 and BACs-36 materials (Wang et al., 2023) were used to further prove the feasibility of this technology under low VOCs concentration, which achieve recovery rates of 99 % for toluene and 95 % for methanol, respectively.

•A review of the existing in-situ heavy oil recovery techniques is presented.•Various aspects of traditional recovery methods are systematically discussed.•The in-situ catalytic upgrading and ...recovery of heavy crude oil is elaborated.•Standards and methodologies are summarized to establish the technological criteria.
Due to the growing global energy demand and increasingly limited availability of conventional or easy-to-produce crude oils, extensive attention is being paid to the exploitation of unconventional heavy and extra-heavy oils. However, their inherent properties, characterized by high viscosity and poor mobility, coupled with the complex reservoir configuration, make the desired recovery processes very challenging. Although several in-situ recovery techniques have been employed in oil reservoirs worldwide, most of them are still suffering from low sweep and displacement efficiencies, high capital investment, potential formation damage and negative environmental footprints.
This paper aims to provide a comprehensive review of the existing in-situ heavy oil recovery techniques, which fall into three categories of thermal injection, chemical injection and gas injection. Different aspects including the fundamental principles, main features, applicability, and limitations of these recovery processes are elaborated sequentially to illustrate the current technology status. Underlying mechanisms causing the relatively low recovery factors will also be pinpointed. Furthermore, this paper focuses on the technology using novel and active catalysts for simultaneous heavy oil upgrading and recovery, especially in the case of metallic nanocatalysts. Rationales, advantages and challenges regarding this in-situ catalytic upgrading technology will be extensively described for their potential implementation in fields. It is noteworthy that many recovery techniques are still limited to the laboratory scale with needs for further investigations. Therefore, this paper also covers the evaluation standards and analytical methodologies of heavy and extra-heavy oil recovery to establish experimental screening criteria. In the end, economic and environmental aspects of the in-situ catalytic upgrading technology have been briefly discussed. The objective of this review is to present a wide range of expertise related to the in-situ heavy oil recovery processes, and to introduce the in-situ catalytic upgrading technology as an effective and environmental friendly heavy oil recovery process.

•The EIPATS exhibits controlled and expedited ionic directional pumping transport properties.•The PSR mechanism combining the ion intercalation/deintercalation processes effectively improve the ...extraction efficiency.•The EIPATS contributed Li+/Na+, Li+/K+, and Li+/Mg2+ selectivity up to 242, 870, and 5032 in mixed solution.•The EIPATS displays a high Li-ion flux to 238% of that of no ion-pumping-assisted process.
Enormous demand and limited resources enable Li-ions extraction as emerging research. Herein, we demonstrate how coupled voltage facilitates lithium-selective extraction across a heterogeneous membrane consisting of a glass-type ceramic electrolyte membrane and a stable conductive composite layer. A cell voltage that directs the one-way selective permeation of Li ions is coupled with a pulse voltage that is applied to the conductive layer to accelerate the transmembrane transport of Li ions. This leads to a high Li-ion flux of 124 mmol m−2h−1, which is enhanced to 238% of the flux of no ion-pumping-assisted process. The proposed electrochemical ion-pumping-assisted transfer system (EIPATS) exhibits an excellent ability to extract Li ions from a mixed electrolyte solution, achieving Li+/Na+, Li+/K+, and Li+/Mg2+ selectivity ratios of 242, 870, and 5032, respectively. The proposed EIPATS featuring a heterogeneous membrane anticipates wide potentials in sustainable resource recovery.

•Increasing the substrate concentration helped to improve the reactor tolerance.•In the P2 phase, side reactions impeded the removal of NO2–-N.•Filamentous bacteria, Ca and P ...synergistically promoted sludge granulation.•Anammox bacteria were reciprocal symbiosis with some heterotrophic bacteria.
Most of the current studies have focused on the inhibition of anaerobic ammonium oxidation (anammox) by substrates, however, little attention has been paid to the recovery process of the reactor after inhibition. Therefore, we investigated the changes in reactor performance, granular sludge structure, and microbial community during the recovery phase after being inhibited by a high nitrogen load for 15 d. The nitrogen removal rate of the reactorwasrestored to pre-inhibition levels after 75 d of recovery, and the stoichiometric ratio converged to the theoretical value. The surface of the granular sludge developed into a broccoli-like structure, and the Ca and P contents of the granules increased from 6.88% and 4.39% to 24.42% and 13.88%, respectively. The abundance of the anammox bacterium Candidatus brocadia increased from 5.86% to 12.10%, and network analysis indicated that SMA102 and SBR1031 were positively correlated with the occurrence of Candidatus brocadia.
•Introduction of a novel conductive filament-based heater (CFH) to carbon nanotubes (CNTs) gas sensor.•Evaluation of effect of Vheating on the response percentage of CFH-embedded CNTs gas sensor.•Low ...energy consumption of only 475 nJ for recovery when utilizing CFH.•Evaluation of humidity effects on CFH-embedded CNTs gas sensor.
Carbon nanotubes (CNTs) gas sensors have slow recovery times and are susceptible to dampness, impacting their responsiveness. Different energy sources, like heaters, have been utilized to tackle this problem, but they are high in energy consumption and have size limitations. This study introduces a conductive filament-based heater (CFH) designed to enhance the recovery time and humidity tolerance of CNTs gas sensors, which is simply configured perpendicular to the CNTs gas sensor. As a result, when using CFH, we observed that after a gas sensing, it returns to its initial state within 1 ms, which is 35x105 times faster a recovery speed than that of without a heater, and only 475 nJ of energy was consumed for recovery. In addition, in the evaluation of humidity on the CFH-embedded CNTs gas sensor, the humidity had the least effect on the sensor using a CFH with heating voltage of 0.7 V ranged from 0.2 to 0.7 V, which was caused by the highest temperature and lowest absorption rate of water molecules on the surface of CNTs. The results suggest that the proposed CFH is an adaptable technique that can be used with various gas sensors including CNTs gas sensors that need an additional energy source.

This paper presents a novel multigeneration framework based on fossil fuels, which offers several advantages such as high thermodynamic efficiency, low electricity and liquid carbon dioxide (CO2) production costs, and significantly reduced pollutant emissions. The simulation was carried out using the Aspen HYSYS software. The thermodynamic analysis revealed that the process achieves a total exergy efficiency of 86 % and an energy efficiency of 31.36 %. The integrated system yields various products, including 597.6 kmol/h of liquid CO2, 3484 kmol/h of desalinated water, 17,600 kmol/h of natural gas for the trunk line, and 41742.1 kW of power. The analyses further demonstrated that the total exergy destruction in the process amounts to 118071 kW, with contributions from the HPGU, NHPGU, MNPGU, and CSLU units of 30.1 %, 22.23 %, 30.36 %, and 17.29 %, respectively. Regarding environmental impact, the analysis revealed that the indirect emissions from the process are negligible. When the CO2 recovery rate exceeds 99 %, the direct emission amounts to 153.72 kg/h, and the pollution intensity of the proposed scheme is 3.68 gCO2/kWhel, which is lower than that of other technologies. Additionally, the economic analysis indicated that the production costs of CO2 and electricity in the proposed process are 0.075 $/kgCO2 and 0.048 $/kWh, respectively.

•COSMO-RS model was used to rationally design natural deep eutectic solvent (NADES).•The NADES has an excellent lutein recovery ability from microalgal biomass.•Different parameters ...including solvent systems, extraction time and temperature were optimized.•The new fenchyl alcohol/thymol-based NADES improves the stability of lutein.•Hydrogen bond and Van der Waals interaction play vital roles in recovery and stabilization.
Lutein is an important functional food ingredient. However, its recovery processes developed so far seem to fail in sustainability criteria, regarding the urgent need for improved extraction ability while maintaining stability. This work aimed to study the design and application of natural deep eutectic solvent (NADES) for lutein recovery from Scenedesmus sp with the aid of COSMO-RS. The performance of the novel fenchyl alcohol/thymol-based system was studied comprehensively under different extraction parameters. Furthermore, thermal, light and storage stability of lutein in NADES were investigated. It was found that lutein recovery from microalgae should be performed using equimolar hydrogen-bond acceptor/donor at 60 °C within 70 min. The NADES could increase lutein yield compared with the conventional methodology using organic solvents. Besides, it significantly enhanced the lutein stability under various conditions. Hydrogen bond and Van der Waals interaction play crucial roles during target processing, elucidated by theoretical calculations and nuclear magnetic resonance.
