The use of carbon dioxide as a carbon source for the production of liquid hydrocarbons to be used as fuels is an attractive area because of current climate concerns, reliance on foreign petroleum, and the possibility of exploring novel chemistry.  Previous work has shown that Fe/Mn supported on Al2O3 and promoted with K is an active catalyst for the hydrogenation of CO2 into light olefins.  Furthermore, it has been demonstrated that Ni silica-alumina catalysts can oligomerize olefins into liquid hydrocarbons.  The interest in moving these chemistries towards an integrated process has led to designing and testing suitable catalysts within fixed bed, tubular reactors.  These small diameter tubular reactors are being modeled computationally to predict product formation so that they can be used as models for micro-channel processes.  This presentation will discuss the progress in moving towards the integration of hydrogenation and oligomerization processes and the effects of catalyst composition and reactor design on CO2 conversion, olefin production, and selectivity toward C9-C16 product hydrocarbons.
