Abstract

The invention discloses a kaolin product for a catalytic cracking catalyst and a preparation method of the kaolin product, which belong to the technical field of kaolin preparation. The method is technically characterized by comprising the following steps: S1, crushing 90% or above of halloysite in percentage by mass in the excavated product, and screening to obtain a kaolin base material; S2, preparing 100-120 parts of a kaolin base material into slurry, adding 50-60 parts of chlorine dioxide microcapsules into the slurry, adding 0.5-0.8 part of a dispersing agent, blending and uniformly stirring; S3, adjusting a pH value of the slurry to 6-7, then adding 0.65-0.9 part of sodium hydrosulfite into the slurry, and uniformly stirring; S4, concentrating the slurry, and carrying out filter pressing dehydration to obtain a filter cake; and S5, drying the filter cake, and crushing to obtain the finished product. The product has the advantage of improving the porosity and specific surface area of the halloysite.

Description

technical field [0001] The invention belongs to the technical field of kaolin preparation, more specifically, it relates to a kaolin product for catalytic cracking catalyst and its preparation method Background technique [0002] Catalytic cracking is a process in which a series of chemical reactions occur in crude oil at a certain temperature (460°C to 550°C) with the participation of a catalyst. Research on catalytic process and catalytic cracking catalyst (FCC) is a core technology and an important scientific and technological basis in today's petrochemical industry. In the history of the development of catalytic cracking catalysts, it has roughly experienced three major changes. For the first time, activated clay was replaced by artificially synthesized aluminum silicate gel, which increased the activity by 2 to 3 times and significantly improved the selectivity. The second time was to use molecular sieves, which greatly improved the level of catalytic cracking, increa...
