Abstract

A reactor design for the selective dehydrogenation of propane was presented. The reactor design comprises reformer-type reactor modules with lanes of tubular reactors and burners. The tubular reactors contained a proprietary catalyst system and operated with a propane/steam feed. The process was characterized by a high selectivity and once-through yield and long on-stream times. A simulation model, consisting of a Langmuir-Hinshelwood kinetic reactor model coupled with a CD model for the furnace, was used to optimize he reactor design. Economic evaluation showed a clear benefit, having $20-25/ton lower propylene production costs than for existing processes on a 150,000 ton/yr basis. The improved economics were basically due to the combination of both a highly selective and stable catalyst and an efficient reactor design.
