ABSTRACT A catalyst suitable for the high pressure gasification of heavy hydrocarbons to produce methane-containing gases is a calcined coprecipitated-aluming containing from 50 - 65% Ni on a calcined unreduced basis. The catalyst contains (1) from 0 to not more than 0.43% K and from 0 to not more than 0.1% Na, (2) the combined weights of Na + K does not exceed 0.011 gm atoms/ 100 gm of catalyst, (3) the ratio of Na : K falls within the area defined by ABCDEO in Figure 1 of the drawings and (3) at combined Na + K weights of from 0 to 0.01% the water loss is not more than 11.2%. The catalysts are prepared with the aid of a filtering aid selected from (NH4)2 CO3, Na2 CO3, K2CO3, Na NO3 or K NO3 to obtain low levels of alkali in the precursor. The catalyst may be employed for steam reforming reaction to produce methane-containing gases.
