Title:
改良された微細球FCC触媒
Document Type and Number:
Japanese Patent JP3827016
Kind Code:
B2
Abstract:
An in situ process for making improved zeolitic fluid cracking catalyst by spray drying a mixture of hydrous kaolin and spinel, essentially free from metakaolin, calcining the resulting microspheres to convert the hydrous kaolin to metakaolin, and reacting microspheres composed of a mixture of spinel and metakaolin forms of calcined clay with a seeded alkaline sodium silicate solution. The weight percent of hydrous kaolin in the starting (uncalcined) microspheres is greater than the spinel content.
