Propene and steam reaction
WebWe consider three different reaction pathways for handling propane feedstock, which are: steam cracking of propane, Pt-based propane dehydrogenation (Pt-PDH), and Cr-based propane dehydrogenation (Cr-PDH). Steam cracking of propane mainly produces ethylene. It employs complex furnaces operating at high temperatures, as in steam pyrolysis of ethane. WebEthene is mixed with steam and passed over a catalyst consisting of solid silicon dioxide coated with phosphoric(V) acid. The temperature used is 300°C and the pressure is about …
