More Information
Summary:Provided here are methods and systems for preparing a solid supported modified zeolite catalyst for use in the fluid catalytic cracking of a hydrocarbon feedstock, a such as a feedstock with a boiling point of less than 330 °C. Methods include preparing an alkaline treated zeolite, passivating by phosphatation, and combining with alumina and silica slurry to result in a spray dryable catalyst precursor. The spray dried modified zeolite catalyst can be used in a fluid catalytic cracking unit to convert light hydrocarbon feedstocks to ethylene and propylene enriched product streams.
