SYNGAS TO LOWER OLEFIN SYNTHESIS OVER BULK Mo2N CATALYST

Fischer-Tropsch to lower olefins (FTLO) is a very attractive process to convert syngas directly to lower olefins. The introduction of this process in big industrial scale units will help to meet the increasing demand of lower olefins in the petrochemical industries. The opportunity to utilize the renewable biomass sources of carbon raw materials will have beneficial environmental effect. Herein, we are reporting the results of the reaction over bulk molybdenum catalysts for FTLO process. The reaction products obtained at 275 degrees C and 21.8 atm total pressure from conversion of reaction mixture with composition of CO:H-2:Ar = 42.7:34.6:20.8 at GHSV = 1.3 mol/gcat h(-1) contains mixture of C-2-C-4 hydrocarbons. From them 62.4% were olefins, within which 60.4 vol. % was propylene. Selectivity toward both olefins and paraffins was 35.2% and 21.2%, correspondingly.
