       By the use of water gas (CO:H₂=1:1) instead of H₂-enriched synthesis gas (CO:H₂=1:2), it has been found that this catalyst gives (a) yields of hydrocarbons comparable with those produced from synthesis gas, (b) gaseous preponderating over liquid hydrocarbons, and (c) lower yields of CH₄ which remain almost constant with increasing space velocity.  The experiments were carried out at 195° and 1 atm., and a maximum yield (125 gm./m.³ of gas) was obtained with a space velocity of 0.9 l./gm. of Ni.  The catalyst used is described in abs. 1187.
