The conversion of a mixture of 10%
of an ATR resid with a FCC VGO feedstock was evaluated with two equilibrium
catalysts of the conventional and resid type at 550 °C and contact times up
to 25 s, and compared with the conversion of the base VGO and ATR under the
same conditions. Under these circumstances, the overall conversions of the
mixture were not very different from those of the base VGO in the case of the
resid catalyst, but increased up to 5 percentage points with the conventional
and more active catalyst. For a given conversion level, the yields of the main
hydrocarbon groups like dry gas, LPG and gasoline did not change significantly,
and were consistent with the reactivity of the pure reactants (VGO and ATR),
that showed essentially the same selectivities. The higher coking trend of the
ATR was observed moderately in the case of the most active catalyst. The most
important changes were noticed in the composition of the various products; for
example, with both catalysts, the gasoline cuts produced by the ATR-VGO mixture
were less aromatic and more olefinic than those obtained with the pure VGO. It
was shown that in order to achieve realistic results in the evaluation of the
addition of resid to a FCC feedstock, it is necessary to consider
simultaneously the mixture intended, the proposed catalyst and the operative
conditions.
