Commercial application of catalyst LIP- 300 for high gasoline and more propylene yield in catalytic cracking unit

The commercial application of catalyst LIP-300 in a 3. 0 Mt/a catalytic cracking unit of Lanzhou Petrochemical Company,PetroChina,was introduced. The results showed that in the case of not changing the main process conditions, after using LIP-300,the yields of slurry oil and diesel reduced by 1. 05 and 2. 73 percent points,the yields of gasoline,liquified petroleum gas and propylene increased by 0. 94,2. 48 and 1. 04 percent points respectively. Gasoline research octane number increased by 0. 6 units,while the olefin volume fraction in gasoline reduced by 1. 0 percent point.
