Title:
NICKEL-BASED CATALYST, AND PREPARATION METHOD THEREFOR AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2024/050836
Kind Code:
A1
Abstract:
A nickel-based catalyst precursor, comprising an active component, an adhesive, and a composite support. The active component is a mixture of nickel and magnesium oxide, and the composite support is one or more of silicon oxide, aluminum oxide, cerium oxide, zirconium oxide, and a molecular sieve. The nickel-based catalyst precursor is obtained by means of spray forming, and can efficiently and stably remove sulfur in benzene. The present invention further provides a preparation method for the catalyst precursor, comprising the steps of: 1) weighing materials according to proportions, stirring components except an adhesive in deionized water and mixing same well to obtain a suspension A, the solid content of the suspension A being 30-50 wt%; 2) homogenizing and dispersing the suspension A under a cold water bath condition for 1-3 h; 3) adding the adhesive in an addition amount of 1-5% to form a suspension B; 4) homogenizing and dispersing the suspension B under the cold water bath condition for 1-3 h; and 5) performing spray forming on the suspension B. The active component is more uniformly dispersed, and the obtained product has larger pore channels which are conducive to the diffusion of reaction raw materials. The preparation process is simple, the processing cost is low, and less three wastes are generated.
