Recent advances in biochar-based adsorbents for CO2 capture

Carbon Capture Science & Technology, Journal Year: 2022, Volume and Issue: 4, P. 100059 - 100059

Published: July 14, 2022

The global industrialization accelerates the use of fossil fuels and hence excessive emissions greenhouse gasses, especially carbon dioxide (CO2), which poses a serious threat to ecological environment. CO2 capture is considered as potential strategy reduce amount released into atmosphere. development adsorption materials that are both economically feasible effective most critical issue. Biochar promising candidate for among materials. It offers diverse range raw lower environmental impact than other adsorbent Even though pristine biochar could be employed directly capture, it generally exhibits poor performance. Therefore, needs modified in practical applications improve physicochemical properties such specific surface area, pore structure, functional groups. This paper summaries recent research advances biochar-based adsorbents adsorption. Pre-combustion technology post-combustion investigated. production influence process conditions on capacity described detail. mechanism also discussed, summarized physical chemical adsorption, respectively, well corresponding presentation some current methods physical/chemical modification biochar. Finally, future prospects proposed order provide guideline by Despite progress made more efforts needed produce with higher long-term stability large-scale capture.

Machine-learning-aided thermochemical treatment of biomass: a review

Biofuel Research Journal, Journal Year: 2023, Volume and Issue: 10(1), P. 1786 - 1809

Published: Feb. 28, 2023

Thermochemical treatment is a promising technique for biomass disposal and valorization. Recently, machine learning (ML) has been extensively used to predict yields, compositions, properties of biochar, bio-oil, syngas, aqueous phases produced by the thermochemical biomass. ML demonstrates great potential aid development processes. The present review aims 1) introduce schemes strategies as well descriptors input output features in processes; 2) summarize compare up-to-date research both ML-aided wet (hydrothermal carbonization/liquefaction/gasification) dry (torrefaction/pyrolysis/gasification) (i.e., predicting oil/char/gas/aqueous thermal conversion behavior or kinetics); 3) identify gaps provide guidance future studies concerning how improve predictive performance, increase generalizability, mechanistic application studies, effectively share data models community. processes envisaged be greatly accelerated near future.

Hydrothermal conversion of biomass to fuels, chemicals and materials: A review holistically connecting product properties and marketable applications

The Science of The Total Environment, Journal Year: 2023, Volume and Issue: 886, P. 163920 - 163920

Published: May 6, 2023

Biomass is a renewable and carbon-neutral resource with good features for producing biofuels, biochemicals, biomaterials. Among the different technologies developed to date convert biomass into such commodities, hydrothermal conversion (HC) very appealing sustainable option, affording marketable gaseous (primarily containing H2, CO, CH4, CO2), liquid (biofuels, aqueous phase carbohydrates, inorganics), solid products (energy-dense biofuels (up 30 MJ/kg) excellent functionality strength). Given these prospects, this publication first-time puts together essential information on HC of lignocellulosic algal biomasses covering all steps involved. Particularly, work reports comments most important properties (e.g., physiochemical fuel properties) from holistic practical perspective. It also gathers vital addressing selecting using downstream/upgrading processes reaction (HHV up 46 MJ/kg), biochemicals (yield >90 %), biomaterials (great surface area 3600 m2/g). As result vision, not only summarizes but analyzes discusses present future applications, establishing an invaluable link between product market needs push transition laboratory industry. Such pioneering approach paves way development, commercialization industrialization develop zero-waste biorefinery processes.
