- the present invention it is possible to introduce a metal deactivator without lowering the catalytic activity.
- the catalyst poisoning metal contained in the raw material heavy hydrocarbon oil is efficiently inactivated, and the amount of generated hydrogen and coke is reduced. It has a small amount, excellent cracking activity and residual oil processing ability, and can obtain gasoline and LCO fractions in high yield without drastically lowering the octane number. It can provide a highly durable FCC catalyst (more than twice the life of the standard catalyst) that can be maintained.
- the FCC catalyst of the present invention exhibits, as an additional effect, a binding ability with sulfur, and can reduce SOX in exhaust gas from the regeneration tower during catalyst regeneration.
