Abstract
The influence of the reaction mixture composition on the catalytic properties of the Mo1V0.24Sb0.23Nb0.08Ce0.01Ox/50 wt.% SiO2 catalyst in the reaction of oxidative dehydrogenation of ethane into ethylene at a temperature of 400-440 °C was investigated. It has been shown that at a high concentration of ethane in the reaction mixture C2H6:O2 = 74:26 (% vol.) and C2H6:O2 = 80:20 (% vol.), the productivity of the process for ethylene is 153-157 gC2H6/(kgcat. h). The catalyst stable work in highly concentrated reaction mixtures at 400–420 °C. This allows the process of oxidative dehydrogenation of ethane to be carried out with recycling of the reaction mixture at an ethane conversion of 20–30%.
