METHOD FOR PREPARING ACROLEIN

METHOD FOR PREPARING ACROLEIN

Provided is a process for preparing acrolein by catalytic gas phase oxidation comprising (a) providing a reaction gas comprising (i) 5 to 10 mol % propylene, (ii) 0.02 to 0.75 mol % propane, and (iii) 0.25 to 1.9 mol % of a fuel mixture comprising at least one of methane and ethane, wherein the mola...

Zusammenfassung:Provided is a process for preparing acrolein by catalytic gas phase oxidation comprising (a) providing a reaction gas comprising (i) 5 to 10 mol % propylene, (ii) 0.02 to 0.75 mol % propane, and (iii) 0.25 to 1.9 mol % of a fuel mixture comprising at least one of methane and ethane, wherein the molar ratio of the total amount of propane, methane, and ethane to the total amount of propylene is from 0.01:1 to 0.25:1, and (b) contacting the reaction gas with a mixed metal oxide catalyst comprising one or more of molybdenum, bismuth, cobalt, and iron.
