Activated alumina catalyst carrier refers to white powder or formed alumina solid, which is the most widely used catalyst carrier. Strip and spherical alumina are mostly used as catalyst carriers in fixed bed reactors. Microspherical alumina carrier Mostly used in fluidized bed reactors. Alumina supports with different shapes, strengths, crystal forms, specific surface areas, pore volumes, pore size distributions, and surface acid-base strengths can be customized according to customer needs. The shape of the product mainly includes spherical, cylindrical and strip-shaped, and the strength is 10-200N/piece. The crystal form is divided into trihydrate alumina, hydrated alumina, rho alumina, γ alumina, X alumina, α alumina, The specific surface area and pore volume can reach up to 350㎡/g and 0.7cm³/g respectively. It is widely used in the production of catalysts by equal impregnation and excess impregnation methods. The loaded precious metals gold, silver, platinum, palladium, rhodium, iridium, Transition metals such as iron, manganese, copper, and zinc all have excellent high-dispersion properties.
