Abstract: A device and method for preparing in-situ molded biochar with high specific surface area. Crushed and mixed biomass and modifier are fed into a hot pressing and pyrolysis device, and hot-pressing molding and pyrolysis carbonization are completed synchronously, which solves the problem of multiple steps and complicated equipment in the existing preparation process for molded biochar material. In-situ bonding molding is realized by adhesion, bridging, cross-linking and mechanical interlocking functions of low-temperature molten & softened lignin and pyrolytic tar. No additional cross-linking agent is needed in this process, so the production cost is low. Covering and suffocating actions of trace flame retardant modifier are utilized to reduce the temperature of biomass pyrolysis carbonization, inhibit excessive ablation and accelerate polycondensation reaction, thus to improve the specific surface area and yield of a product, and improve the cost performance of the product.

Abstract: The present invention relates to a self-powered time sharing reaction system and method for organic materials pyrolysis and combustion. The system comprises a time sharing reactor for pyrolysis and combustion, a feeder, a recovery apparatus for pyrolysis volatility products and a flue gas purifier. The whole process mainly consists of two time sharing stages of pyrolysis and combustion: organic materials are sent into the time sharing reactor for pyrolysis and combustion, and solid thermal carrier rapidly heats the organic materials and the pyrolysis reaction takes place. The produced pyrolysis volatility products enter the recovery apparatus for the recycling of the pyrolysis gas and pyrolysis oil; when the pyrolysis reaction is over, fill air into the time sharing reactor for pyrolysis and combustion to combust with the rest of the pyrolysis volatility products and the pyrolysis residue in the reactor. The heat produced during the combustion heats the solid thermal carrier, the flue gas is released after being purified, the heated solid thermal carrier is left in the time sharing reactor for pyrolysis and combustion to provide energy for the next organic materials pyrolysis. The process is thus repeated. The system has the advantages of cascade utilization of energy, short time of pyrolysis reaction and high efficiency of heat transfer.

Abstract: A method for enhancing geological storage by injecting nanoparticles to stabilize CO2 microbubbles, which belongs to the technical field of multiphase flow. The method first improves the physical properties of the fluid by pre-mixing CO2 and nanoparticles, and then the fluid is transported to the underground through high-pressure pipelines, and then CO2 microbubbles containing nanoparticles are generated through a dense perforated plate arranged by an injection well to improve the dissolution rate and sweep efficiency of the gas in the saline aquifer, so as to enhance the later mixing of the fluid. The combined injection can improve CO2 storage capacity and storage safety, and further reduce the risk of gas leakage in the reservoir.
