Process to improve formulations of hydrocarbon conversion catalysts through removal and modification of detrimental particles and reuse of modified fractions
An improved hydrocarbon conversion catalyst is obtained through removal and modification by various means, of detrimental large and/or small particle fractions. Such modified fractions may be reused in the same or similar processes. The improved catalyst is advantageous to a wide range of hydrocarbon conversion processes.
1. An improved Deep Catalytic Cracking process comprising the step of subjecting a heavy hydrocarbon feedstock to an improved catalyst composition, wherein the improved catalyst composition is prepared by a process comprising the steps of a. spray-drying a mixture comprising a hydrocarbon conversion catalyst to form solid hydrocarbon conversion catalyst particles; removing greater than 50% of the particles below a minimum particle size threshold; and b. removing greater than 50% of particles above a maximum particle size threshold.
2. An improved BIOMASS conversion process comprising the step of subjecting a biomass to an improved catalyst composition, wherein the improved catalyst composition is prepared by a process comprising the steps of a. spray-drying a mixture comprising a hydrocarbon conversion catalyst to form solid hydrocarbon conversion catalyst particles; removing greater than 50% of the particles below a minimum particle size threshold and greater than 50% of particles above a maximum particle size threshold.
3. An improved naphtha cracking process comprising the step of subjecting naphtha to an improved catalyst composition, wherein the improved catalyst composition is prepared by a process comprising the steps of a. spray-drying a mixture comprising a hydrocarbon conversion catalyst to form solid hydrocarbon conversion catalyst particles; removing greater than 50% of the particles below a minimum particle size threshold and greater than 50% of particles above a maximum particle size threshold.
