ABSTRACT:
A catalyst for production of methane-containing gases which is formed from a catalyst precursor composed of a mixed precipitate of hydroxides and/or carbonates of nickel and/or cobalt, lanthanum and/or cerium and aluminum, which is obtained by stepwise addition of solutions of alkaline substances to a solution of an aluminum salt, to a solution of a lanthanum salt and/or a cerium salt and to a nickel salt and/or a cobalt salt is disclosed. This stepwise addition of solutions of alkaline substances is accomplished by (1) first stage addition of a solution of an alkaline substance to a solution of an aluminum salt, (2) second stage addition of a solution of an alkaline substance to a solution of a lanthanum salt and/or a cerium salt in the presence of the precipitate-containing solution formed by the first stage addition and (3) third stage addition of a solution of an alkaline substance to a solution of a nickel salt and/or a cobalt salt in the presence of the precipitate-containing solution formed by the second stage addition.
