        Activity of Ni-Co-Si, Ni-Co-Mn-Si and Co-Si alloys has been improved by melting the original alloy in a high-frequency furnace.  With 10 gm. Ni-Co-Si (1:1:2) alloy catalyst a maximum benzine yield of 130 cc. per m.³ was obtained from 1 m.³ of initial gas (33.6% CO and 65.4% H₂).  A small addition of Mn to Ni-Co-Si alloy catalyst appears harmful.  Mn checks hydrogenation of the catalyst and accelerates polymerization.  The activity of Co-Si catalyst increases with decrease in particle size.  H₂ treatment of Co-Si catalyst is detrimental.  The optimum temperature for Co-Si catalyst is 230°.  The activity is lower than that of Ni-Co-Si alloy catalysts.
