Claims12
A process for improving the physical and catalytic properties of a sol based fluid cracking catalyst which comprises the steps of;
- (a) preparing an acid aluminum sulfate silica sol binder component,
- (b) preparing a clay slurry component,
- (c) combining components (a) and (b),
- (d) preparing a zeolite slurry component,
- (e) preparing an alumina slurry component,
- (f) adding an effective amount of an acid stable anionic fluorocarbon surfactant to at least one of the components,
- (g) combining the components and spray drying,
- (h) washing, exchanging, drying, calcining and recovering the catalyst product.
A process for improving the physical and catalytic properties of a fluid cracking catalyst by adding an effective amount of an acid stable anionic fluorocarbon surfactant to the catalyst components.
