     Coke-oven gas containing 5-6% CO is suitable for this synthesis with a Ni-Mn-Al catalyst.  As a result of the ratio of H₂:CO, which is higher than that of gas mixtures usually used for this synthesis, the reaction temperature must be reduced from 195° to 160°.  The process is carried out so that a contraction of 20-25% is obtained, by which all of the CO but none of the CO₂ is used.  In this way 20-22 cc. of hydrocarbons is obtained/m.³ of gas, of which 75% is gasoline.  The heating value of the end gases is increased from 4,200 to 5,300 cal.  Because of the S content of the gas, the reaction temperature must be increased slowly, 25° in 4 weeks in order to compensate for poisoning of the catalyst.  After this time, a complete reconditioning of the catalyst is necessary.  The catalyst absorbs all the gaseous S.
