Hs. Cerqueira et al., MATHEMATICAL-MODELING AND SIMULATION OF CATALYTIC CRACKING OF GAS-OILIN A FIXED-BED - COKE FORMATION, Applied catalysis. A, General, 164(1-2), 1997, pp. 35-45
In the present work a 12-lump model for the catalytic cracking of gaso
il in a fixed bed microreactor was solved, with the differential-algeb
raic approach, using previously published kinetic constants, The influ
ence of different feedstocks and injection times were studied. Taking
into account the sequential design of experiments, this model was used
as a virtual data generator to validate a simplified 5-lump model. Th
e 5-lump model was also validated with real microactivity test (MAT) d
ata. Although the naphthenic feed yielded more gasoline, the aromatic
feed was responsible for more coke on catalyst than were the other fee
ds. Simulation results for the 5-lump model are in agreement with expe
rimental and virtual data. (C) 1997 Elsevier Science B.V.
