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.

A method for enhancing geological storage by injecting nanoparticles to stabilize COmicrobubbles, which belongs to the technical field of multiphase flow. The method first improves the physical properties of the fluid by pre-mixing COand nanoparticles, and then the fluid is transported to the underground through high-pressure pipelines, and then COmicrobubbles 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 COstorage capacity and storage safety, and further reduce the risk of gas leakage in the reservoir.
