FLUID CATALYST COMPOSITIONS

摘要

FLUID CATALYST COMPOSITIONS of the Invention Fluid catalyst particles are mixed with an inorganic colloid to improve the density and attrition resistance thereof. Typically, a fluid cracking catalyst composition containing silica-alumina hydrogel, clay and/or crystalline alumino silicates (zeolites) is mixed with an inorganic sol of silica, alumina or silica-alumina having particles of less than about 0.05 micron.
