摘要

A sub-micron sample of Y zeolite was synthesized without template with a Si/Al ratio equal to 2.75. This sub-micron zeolite was embedded in a FCC catalyst formulation at two different contents: 10 and 20wt%. The catalysts were hydrothermally deactivated and evaluated in a fixed bed reactor at various catalyst-to-oil ratios and the results compared to the performance of a regular HUSY containing deactivated catalyst. Although the activity of the samples containing sub-micron zeolites in the cracking of gas oil was reduced when compared to a regular HUSY containing catalyst, the selectivity was affected with a reduction in the coke and an increase in both light cycle oil (LCO) yield and the LCO/bottoms ratio. Accordingly to that, those catalysts may be suitable for resid FCC applications.
