ABSTRACT:
This invention relates to a hydrocarbon conversion processes, e.g., hydrocracking, cracking, alkylation, etc., using a silicon enhanced amorphous silica-alumina (SEASAL) composition. The composition is characterized in that from about 3 to about 22 mole percent of the aluminum atoms in a host amorphous silica-alumina have been replaced by silicon atoms. Additionally, the SEASAL contains from about 0.5 to about 10 weight percent fluoride and has a cracking activity of at least 30%. The SEASAL is prepared by reacting a host amorphous silica-alumina with a fluorosilicate salt, thereby removing aluminum atoms and inserting silicon atoms.
