ABSTRACT:
An ammonia synthesis catalyst precursor having a high BET surface area and containing oxides of iron, cobalt, aluminum, and an alkali metal of atomic number equal to, or greater than, 19. On reduction the precursor gives a catalyst having a high initial activity relative to that of a catalyst obtained by reduction of a standard fused, cobalt-free, precursor.
The precursor may be made by precipitation followed by calcination.
