The effects of bimetallic interactions for CO2-assisted oxidative dehydrogenation and dry reforming of propane

The catalytic reduction of CO2 by propane may occur via dry reforming to produce syngas (CO + H-2) or oxidative dehydrogenation to yield propylene. Utilizing propane and CO2 as coreactants presents several advantages over conventional methane dry reforming or direct propane dehydrogenation, including lower operating temperatures and less coke formation. Thus, it is of great interest to identify catalytic systems that can either effectively break the C-C bond to generate syngas or selectively break C-H bonds to produce propylene. In this study, several precious and nonprecious bimetallic catalysts supported on reducible CeO2 were investigated using flow reactor studies at 823 K to identify selective catalysts for CO2-assisted reforming and dehydrogenation of propane.
