Effect of precursor anion on performance of catalysts of oxidative coupling of methane (OCM)

The performance of OCM catalysts are affected by many parameters. Precursor anion that is used for catalyst preparation plays a significant role in catalytic properties. In this study, we want to investigate the influence of the precursor anion on the conversion, selectivity and yield of BaTiSnO3 as an OCM catalyst. Carbonate, hydroxide and propionate of barium used for preparation of OCM catalysts for this purpose. The result of experiments showed that based on the extent of effects on the catalytic performance for SnCl2 promoter, the anions can be ranked in the order of: propionate > carbonate > hydroxide.
