Abstract: Suspension catalytic distillation (SCD) has been developed recently as an innovative
technology in catalytic distillation. In this paper, a brief introduction to SCD is given
and an equilibrium stage (EQ) model is developed to simulate this new process for synthesis
of linear alkylbenzene (LAB) from benzene, and 1-dodecene.Since non-ideality of this
reaction system is not strong, EQ model developed could be applied to it
successfully.Simulation results agree well with experimental data, and indicate some
characteristics of SCD process as an advanced technology for the production of LAB: 100%
conversion of olefins, low temperature (90-100℃) and low benzene/olefin mole ratio.

Key words: suspension catalytic distillation, equilibrium stage model, linear alkylbenzene
