        Of the catalysts Ni-Mn, Ni-Mn-Al, Ni-Mn-Cu, Ni-Mn-Cr, Ni-Th-Hg, Co-Th, and Co-Mn, the most active were Co-Th, Co-Mn, Ni-Mn-Cr, and Ni-Mn-Al.  The method of preparation of the catalyst greatly affects its activity.  The reaction temperature is very important to the life of the catalyst.  A high temperature yields less solid hydrocarbons, which are deposited on the catalyst.  The best temperature is that at which 7-10% CH4 is formed.  The presence of small amounts of NH3 in the reaction gas increases the yield of gasoline, particularly with catalysts precipitated on fullerís earth.  Asbestos carrier yields the best catalysts.  12 refs.
