Abstract

The invention discloses a bulk phase catalyst and a preparation method thereof. The bulk phase catalyst is prepared from an inorganic oxide precursor, a hydroxide gel and an active metal hydroxide gel serving as raw materials by molding and roasting. In the preparation process of the bulk phase catalyst, because the hydroxide gel contains a surfactant and hydrocarbon components, after the hydroxide gel is molded and roasted, the nano oxide particles formed by dehydrating the polymerized hydroxide also have a rod-shaped basic structure and pile up into a framework structure in an unordered mode. Therefore, the catalyst has the advantages of large pore volume, large pore diameter, high porosity, large orifices on the outer surface, good pore penetrability, and contribution to increasing the impurity deposition and prolonging the operation period of the catalyst.

Description

technical field [0001] The invention relates to a bulk phase catalyst and a preparation method thereof, in particular to a macroporous bulk phase catalyst and a preparation method thereof. Background technique [0002] Bulk phase catalyst refers to a supported catalyst whose active components are dispersed on the carrier. It does not use an inactive carrier as a carrier. Even if it contains a certain amount of inactive components, it also plays a role in improving the strength of the bond. Most of the catalyst is composed of active components, and the content of active components is generally not limited, sometimes called bulk catalysts. Since bulk catalysts can get rid of the limitation of metal content, and at the same time, the ratio of each active component in the catalyst can be adjusted arbitrarily, so that the activity of the catalyst can be greatly improved, so bulk catalysts are getting more and more attention. [0003] Bulk phase catalysts are usually used in reac...
