        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 fuller’s earth.  Asbestos carrier yields the best catalysts.  12 refs.
