Abstract
Commercial catalysts are prepared combining the various ingredients into a catalytic binder system which has been freed of sodium so that the catalyst ingredients can be preferably spray dried and used in Fluid Catalytic Cracking or Reduced Crude Conversion hydrocarbon conversion operations without subsequent washing or drying. Catalysts can even be prepared on site, e.g., in spray drier operations performed in the FCC/RCC refenerator. Low-sodium slurries of any or all of the following ingredients can be employed in the manufacture: zeolites, clays, sols, carbon blacks, sacrificial sieves, acid matrix substances, and getters.
