摘要
A 45 mL bench-scale internal recycle reactor, named a "Riser Simulator" was used to crack a commercial FCC feedstock as well as pure compound mixtures on Octacat and GX-30 catalyst under short reaction times (3 - 10 s). The kinetic constants, related to an eight-lump model, were calculated based on a reactor model which intrinsically includes the effect of molar expansion during cracking. As well, the model takes into account feedstock composition since the gas oil feed is lumped into paraffins, naphthenes and aromatics in both heavy and light fractions. The Riser Simulator is well suited for representing short riser cracking reactions allowing the use of a wide range of conditions thus making it a valuable tool for determination of relevant kinetic data. © 1990.
