摘要：A process for producing ammonia comprising selecting a catalyst precursor characterized by the formula: ##EQU1## wherein A is an alkali or alkaline earth metal or mixture thereof;
M is La, Ce, Pr, Nd, Pm, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Sc, Lu and Y or mixtures;
M' is a group VIII metal, preferably Fe, Co, Ni or Ru or mixtures;
a=0.1 to 4;
b=0.1 to 4;< P>
c=4 to 6; and
provided that the catalyst is free or substantially free of Al or the combination of Al and U, activating the precursor by heating in a non-oxidizing atmosphere and pass N.sub.2 and H.sub.2 over the activated catalyst to produce ammonia.
