  Abstract This paper will present preliminary results from a novel process being developed in our laboratory for the production of high quality F-T gasoline.  The system is a combination of a conventional F-T catalyst combined with a zeolite-shell catalyst.  This system is being designed for the Steam Hydrogasification process using various carbonaceous feedstocks. The chemical speciation and carbon distribution of the liquid fuel produced with the conventional F-T system will be compared to the new system using the zeolite-shell catalyst.  It is found that the zeolite based system shifts the carbon distribution to the lower carbon number species (i.e., C6-C12 range) from the more typical diesel fuel fraction (C12-C20 range) found with FT catalyst systems.  Chemical speciation results will be presented along with a assessment of the total carbon conversion expected for this process within the steam hydrogasification technology.
