Title:
FCC CATALYST ADDITIVE WITH MIXED ALUMINA
Document Type and Number:
WIPO Patent Application WO/2018/170452
Kind Code:
A8
Abstract:
Provided is a Fluid Catalytic Cracking catalyst additive composition and method of making the same. The catalyst additive composition comprises zeolite about 35 wt % to about 80 wt %, preferably about 40 wt% to about 70 wt%; silica about 0 wt% to about 10 wt%, preferably about 2 wt% to about 10 wt%; about 10.5 wt% to 20 wt % alumina and about 7 wt% to 20 wt% P2O5, preferably about 11 wt% to about 18 wt %, and the balance clay which can fall between 0 and 50 wt%. The alumina is typically derived from more than one source, such as at least an amorphous or small crystallite size pseudo-boehmite alumina and then either a either a large crystallite size alumina or other reactive alumina.
