The conversion and product distributions from a mixture of 10%
atmospheric tower bottom resid and a DO hydrocarbon cut similar to LCO that
represented commercial feedstocks were assessed over two equilibrium commercial
FCC catalysts in a laboratory CREC Riser Simulator reactor. The reaction
temperature was 550 °C,
the catalyst to oil ratio was 5.8 and the reaction times were up to 25 s. The
conversion of the mixture as compared to the DO base feed was higher in the
case of the most active, conventional catalyst, and remained very similar on
the resid catalyst. Since the yields of the main hydrocarbon groups dry gas,
LPG, gasoline and coke followed very similar trends when the two pure
feedstocks were converted, the corresponding yields from the mixture also
obeyed that behaviour, and were the consequence of the conversion reached. The
impact of the different catalyst formulations was observed in, for example, the
selectively different yields obtained from the conversion of the resid, and in
the composition of the gasoline. Independently of the catalyst, the gasoline
was more olefinic and less aromatic when the resid was present. It was shown
that in order to evaluate properly a given combination of feeds, catalysts and
conditions, they must be considered together.
