Molybdenum catalysts (both supported and unsupported) have been examined in various stages of preparation and use with respect to BET surface area and low temperature oxygen chemisorption. The results are detailed. X-ray diffraction has been used to characterize ammonium molybdate - after calcination, heated in tetralin under nitrogen and after use in an autoclave. Metal salts have been tested for catalytic effects by heating a tetralin-coal mixture (without hydrogen) at a loading of 1% of the coal. Only ammonium heptamolybdate and stannous chloride had a large incremental effect (based on blank runs with tetralin and catalyst without coal). Differences in liquefaction behavior in tubing bombs and in autoclaves are explained by thermodynamic considerations based on the gas to liquid volume in the two cases. (LTN)
