【 摘 要 】

Catalytic cracking of C13 was carried out on a Z5CaO catalyst using a two stage single reaction to evaluate a 3-lump model of a steady state reaction setting C2 as the objective product. A total volume of 0.0962m3 of kerozene was used over a ten (10) h period using two adjustable feed rates of 7.7 and 8.3 10-5m3/s. Between 400 ± 50oC the reactor performance and the model result showed an excellent correlation of C2 output suggesting that the catalyst ratio and the temperature favored hexane-heptene fragmentation with a methyl radical as a result of the short space time (0.012s). It was observed that the increase in gas phase(Mgas) was responsible for catalyst regeneration since the catalyst mass (Mcat) was constant in the circulating volume. This condition helped the 3-lump model to operate as a two-stage steady state single reaction with a maximum usage of kerozene at a single pass with a 96% yield of ethylene.
