New cracking process has recently come out
In the FCC unit, the C4 and light gasoline components were processed to increase propylene and ethylene production while reducing the olefin content in gasoline, with a slight decrease in octane number.
The process has a plurality of fixed bed reactors operating at a temperature of 500-600 degrees and a pressure of 100-500 kPa, employing a zeolite catalyst capable of achieving high propylene yields. The use of a catalyst results in a smaller reactor size and lower operating costs by operating at a high airspeed, which does not require a dilution stream. The regeneration of the catalyst is achieved by the switching of the reactor system.
