Webprocess a fluid bed reactor with a solid catalyst is used. It is a single pass process meaning that no recycling is used. The propylene conversion is 98%. Operating conditions are: Temperature 400 - 510 °C; p 150 - 300 kPa; the catalyst used is a mix of metal oxides, most commonly bismuth and molybdenum oxides with traces of other metal oxides. WebBP/Sohio patents had the most attractive economics, followed by the process based Mitsubishi patents and then the process based on Asahi patents. Inclusion of a recycle into the processes based on Asahi or Mitsubishi patents (as is being developed by Mitsubishi and BOC), would improve their economics relative to the BP/Sohio propane-based process.
