A charge of neutron activated American Cyanamid 1442A CoMo catalyst with total activity of Co/sup 60/ of approx. 390 ..mu..Ci has been prepared for use in the H-Coal Process Demonstration Unit. Catalysts tested by HRI in (1) a fixed bed with low ash feedstock and (2) an ebullated bed and fixed bed with higher-ash containing feedstocks corroborate other evidence that the regions of high reflectivity near used catalyst surfaces are due to the pressure of containment mineral matter, primarily iron and titanium. Parametric experiments with coal, preasphaltene, asphaltene, and oil, in tubing reactors, show that production of hydrocarbon gases increases in the series oil < asphaltene < preasphaltene, that both a CoMo catalyst and pyrite addition lowers the production of C/sub 1/-C/sub 4/ hydrocarbons, and that pyrite significantly increases the amount of CO and CO/sub 2/ generated.
