Industrial application of solid strengthening agent for HAA catalytic cracking:
After a successful trial on the catalytic unit of changling branch of sinopec, HAA FCC solid refining additive has now been put into use in the changling no.1 catalytic unit of jinan refining and chemical co., LTD. The industrial application shows that the HAA catalytic cracking solid strengthening agent, which accounts for 15% of the total storage capacity of the unit system, can effectively reduce the diesel oil and slurry and increase the yield of gasoline by more than 2 units while keeping the total liquid yield and octane number unchanged.
