The dominant technology for producing propylene is steam cracking. The same technology is used to produce ethylene from ethane. Cracking propane yields a mixture of ethylene, propylene, methane, hydrogen, etc. The yield of propylene is about 15%. The other principal feedstock is naphtha, especially in the Middle East and Asia. Propylene can be separated by fractional distillation from hydrocarbon mixtures obtained from cracking and other refining processes; refi… WebThe dominant technology for producing propylene is steam cracking. A molybdenum-based catalyst is also being used as it is more resistant to poisoning by sulfur-containing impurities in the feedstock. As with all alkenes, unsymmetrical alkenes like propene react with hydrogen bromide in the cold.
