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.
