The present invention provides a gas adsorbent comprising a number of microspheres formed by agglomeration of zeolite and adhesive. Among the plurality of microspheres, at least some of the microspheres have a porous structure and contain inflatable balls inside. In the present invention, the high molecular polymer expansion ball is added into the zeolite microsphere, and more pore structures are created in the zeolite microsphere by utilizing its characteristics of expansion, solidification and rupture at different temperatures. Thus, the adsorption capacity of the zeolite microsphere to air is increased to achieve a better frequency reduction effect.

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.
