摘要

Abstract

A redox process combining propane dehydrogenation (PDH) with selective hydrogen combustion (SHC) is proposed

modeled

simulated

and optimized. In this process

PDH and SHC catalysts are physically mixed in a fixed-bed reactor

so that the two reactions proceed simultaneously. The redox process can be up to 177.0% higher in propylene yield than the conventional process where only PDH catalysts are packed in the reactor. The reason is twofold:firstly

SHC reaction consumes hydrogen and then shifts PDH reaction equilibrium towards propylene; secondly

SHC reaction provides much heat to drive the highly endothermic PDH reaction. Considering propylene yield

operating time

and other factors

the preferable operating conditions for the redox process are a feed temperature of 973 K

a feed pressure of 0.1 MPa

and a mole ratio of H

to C

of 0.15

and the optimal mass fraction of PDH catalyst is 0.5. This work should provide some useful guidance for the development of redox processes for propane dehydrogenation.
