promotor

The effect of BaCl2 promotor on the catalytic properties of Fe-Te-Mo-Ox catalyst of joint oxidative dehydration and oxidative amonolysis of C4 olefins has been examined. The optimal composition of promoted catalyst has been established taking into consideration methacrylonitrile and butadiene yields. The process kinetics has been investigated

The effect of barium salts (nitrate, sulphate, chloride) on the physico-chemical and catalytic properties of Fe:Te:Mo (1:0.85:1) oxide catalyst has been determined for oxidative amonolysis of isobutyl alcohol (IBA) to methacrylonitrile (MAN). The catalyst doped with BaCl2 (Ba/Mo = 0.1) was found to be the best catalyst relatively to the MAN yield. It has been shown that the promotors increase the catalyst specific surface and affect catalyst surface acidity improving the catalyst efficiency.
