FCC high-yield propylene catalytic additive
The highly active propylene production additive produced with shape-selective molecular sieves as the main active component can increase the yield of liquefied gas and propylene when used in combination with the FCC sulfidation catalytic cracking main catalyst. This catalytic additive has a relatively high selective catalytic activity. It has good wear resistance and particle size distribution.
