The invention belongs to the technical field of inorganic porous materials, and discloses a high thermal conductivity inorganic porous composite material for gas adsorption and separation and a preparation method thereof. 0% to 30% of thermally conductive filler; stir and dry mix the inorganic porous material and thermally conductive filler, after mixing evenly, add polysiloxane to it and continue to grind and mix to obtain composite powder; mold the composite powder molding to obtain a composite material; subjecting the composite material to stepwise heating and calcination treatment, and naturally cooling to room temperature to obtain a high thermal conductivity inorganic porous composite material having a three-dimensional silicon-carbon skeleton for gas adsorption and separation. The composite material prepared by the invention has both high thermal conductivity and component adsorption and separation performance, and at the same time, the preparation process is simple and easy to operate, stable in process, easy to master, low in cost, easy to implement, can significantly shorten the cycle of adsorption and separation process, improve separation efficiency, and reduce Process energy consumption. |
