Abstract: A system and method for CO2 capture and electroregeneration and synchronous conversion are provided. The system includes a CO2 capture subsystem, which uses an absorption liquid to capture CO2 and generate a capture liquid; and a CO2 electroregeneration and synchronous conversion subsystem, including a cathode chamber provided with a cathode electrode, a sample inlet, and a sample outlet, an anode chamber having an anode electrode, a sample inlet connected to an outlet of the capture liquid of the CO2 capture subsystem, and a sample outlet connected to the sample inlet of the cathode chamber for introducing CO2 regenerated by anodic oxidation into the cathode chamber for electroreduction, and a balance chamber in the middle having a sample outlet connected to an inlet of the absorption liquid of the CO2 capture subsystem. The system can perform self-circulation and stably operate, to capture, regenerate and convert CO2.

Abstract: The present invention discloses a rapid evaluation method for quality of lignin-pyrolyzed bio-oil and an application thereof, and particularly relates to a rapid evaluation method for quality of lignin-pyrolyzed bio-oil based on radical detection and an application thereof. The method can be used to evaluate the quality of lignin-pyrolyzed bio-oil by detecting the spin concentration of radicals in lignin char obtained by lignin pyrolysis, thus avoiding the complex processes involved in the evaluation for the quality of conventional pyrolyzed bio-oils such as, extraction, separation and detection and reducing the detection costs substantially. The detection method of the present invention is simple and easy to operate, thus achieving the rapid evaluation for the quality of lignin-pyrolyzed bio-oil. Moreover, the detection method of the present invention is non-contact detection without destructive samples, which is applicable to the rapid detection on the quality of lignin-pyrolyzed bio-oil in the field of industry and scientific research. The present invention further broadens the application fields of radical detection and contributes to the development of radical detection technology in the field of pyrolysis, and provides a reliable method for the detection of lignin-pyrolyzed bio-oil, which has good application prospect.

Abstract: A biomass-based porous carbon composite material and preparation thereof and an application thereof in CO2 adsorption are provided. In the biomass-based porous carbon composite material, with a pulping black liquid solid as a precursor, by arc treatment, porous carbon structures capable of physically adsorbing CO2 and basic substances capable of chemically adsorbing CO2 are obtained; with lignin in the precursor as the carbon source, and sodium hydroxide, sodium salts, and small-molecular carbohydrate degradation products in the precursor as the template and activator, porous carbon structures are obtained by arc thermal carbonization and self-activation; the basic substances are obtained by allowing sodium hydroxide and sodium salts in the precursor to undergo arc thermal decomposition. Further, the present disclosure relates to an application of the biomass-based porous carbon composite material in CO2 adsorption.
