Preheats Effect on Distributed Reaction Fuel Reforming

Abstract

Conventional non-catalytic fuel reforming provides low efficiency, large amounts of char and tar and limited control on chemical composition of the syngas produced. In this paper volume distributed reaction technique is used to enhance reformate quality as compared to conventional reforming that uses non-catalytic reforming. Reforming of middle distillate fuels typically utilize preheats of 300–600°C[1,2]. This work investigates the intermediate regimes between volume distributed reaction regime and conventional flame regime for the reforming of JP8 through the chemical and mixing time scale. The results showed that reformate concentrations of fixed gases and most low molecular weight hydrocarbons changed gradually with air preheats. Reaction regime did not drastically change reformate products except for acetylene. In conventional flame regime acetylene concentration rapidly increased upon on entering the reactor.
