摘要：
Fluid catalytic cracking (FCC) commercial units require catalysts with high cracking activity to produce high octane number gasoline fraction to satisfy fuel oil demand and environmental regulations. Previously addition of rare earth metals obtained enhanced cracking activity, but the octane number was decreased by promotion of the hydrogen transfer reaction. This study investigated phosphorus material as a new component of FCC catalyst, to enhance the cracking activity and prevent octane number decrease. Mono aluminum phosphate (Al2O3 center dot 3P(2)O(5) center dot 6H(2)O) induced increased cracking activity and higher octane number in FCC gasoline than rare earth metals.
