▎ 摘 要
NOVELTY - Preparation of composite multi-stage hole catalytic-adsorption material involves taking pseudo-boehmite, sodium aluminosilicate, kaolin, attapulgite, metal salt, graphene oxide as raw materials, performing hydrothermal crystallization, then filtering the product, washing, drying and calcining. USE - Method is used for preparing composite multi-level porous catalytic-adsorption material used as catalyst carrier. ADVANTAGE - The prepared composite catalytic-adsorption material forms multi-level porous catalyst carrier with expanded pore size. The material has improved catalytic-adsorption function. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for the composite multi-stage hole catalytic-adsorption material.
