Abstract
The invention belongs to the technical field of preparation of catalysts from coal gangue, and provides a method for preparing a high-activity petroleum catalytic cracking catalyst from coal gangue. The coal gangue is ground and calcined to generate amorphous meta-kaolin powder, the amorphous meta-kaolin powder is prepared into slurry again, a binder is added, and microspheres are generated through spray drying, namely the high-activity petroleum catalytic cracking catalyst. The kaolin microspheres for the catalytic cracking catalyst are produced by taking coal gangue as a raw material. Calcined kaolin in the kaolin microspheres has certain activity, molecular sieves can be synthesized, and the microspheres have certain strength and meet the requirements of a subsequent crystallization process. Coal gangue is used as a raw material, and a high-activity catalytic cracking catalyst precursor with high additional value is produced through an improved process. On one hand, the requirementsin the field of catalysts can be met, meanwhile, a new profit growth point is opened up for our company, waste is truly turned into wealth, energy conservation and consumption reduction are achieved,and high-added-value comprehensive utilization of the waste coal gangue reaches a new level.
Description
technical field [0001] The invention belongs to the technical field of preparing catalysts from coal gangue, and in particular relates to a method for preparing high-activity petroleum catalytic cracking catalysts from coal gangue. Specifically, it is a technology for preparing highly active petroleum catalytic cracking catalyst microspheres from coal gangue. The microspheres can be used as petroleum catalytic cracking catalysts after crystallization, exchange, roasting and other processes. Background technique [0002] Kaolin is a non-metallic mineral powder material with unique properties. Its applications include papermaking, rubber, plastics, cables, chemicals, paints and coatings, etc. It plays an important role in the development of modern high-tech industries and the upgrading and progress of traditional industrial products. . Coal gangue is a kind of coal-based kaolin. Its characteristic is that the raw ore itself is dark brown, and its whiteness is higher after cal...
