Promotion of cracking catalyst octane yield performance
Patent
·
OSTI ID:5556108
A process is provided for increasing gasoline octane number and/or total gasoline yield in catalytic cracking units by the addition of a very small amount of finely divided shape selective additive promoter, which additive promoter is not intimately combined with a substantial amount of another solid prior to contact with the cracking catalyst. The additive promoter, in one embodiment, is a crystalline aluminosilicate zeolite having a silica to alumina mole ratio greater than about 12 and a constraint index within the approximate range of 1 to 12.
