Abstract
A process for significantly improving the physical and catalytic properties of fluid cracking catalysts (FCC) is disclosed. The invention is a process for manufacturing a fluid cracking catalyst. The process includes adding an effective amount of an acid stable surfactant or an alkaline stable surfactant to a slurry of clay particles and sodium silicate particles. The process then includes forming a sol binder and spray drying the particles. Forming of the dried particles into a catalyst product then occurs.
