Description

technical field [0001] The invention belongs to the field of synthesis of catalyst carrier materials, in particular to the field of synthesis of composite amorphous refractory oxide catalyst carrier materials. Background technique [0002] The catalyst in the heterogeneous catalytic process generally uses a solid catalyst, and the carrier is an important part of the solid catalyst. Carriers can generally be divided into inert carriers and active carriers. Pure oxides such as silica and alumina are generally inert supports. Some acid-base catalyzed reactions require the use of active supports, especially the common acid-catalyzed reactions require the use of active supports with acid centers. Oxides with different valence states and coordination numbers form composite supports to produce acid centers. For example, the common amorphous silica-alumina is an important catalyst active support. On the other hand, some oxides are also compounded in the carrier as support modific...
