A porrous support has been obtained from spherical fused iron catalyst after its potassium ions were dissoluted out by water. Impregnation such a dried porrous support with a mixture of Ce(NO3)3 and KNO3 gave a catalyst with a higher activity for ammonia synthesis. The presence of CeO2 in the catalyze after calcination was confirmed by Xray analysis. The results showed that the optimum ratio of K+ to Ce3+ in impregnation mixture was 1∶1.
