WebThe temperature at the outlet of the radiant coil typically ranges from 775 to 885 °C. The reactor effluent is quickly quenched to prevent further reaction; compressed; and sent to a separation unit for the recovery of ethylene and other products such as methane, ethane, propane, propylene, butylene, and gasoline. [1] Web2.1.2 Propane conversion We 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.
Role of CO2 During Oxidative Dehydrogenation of Propane Over …
In steam cracking, a gaseous or liquid hydrocarbon feed like naphtha, LPG or ethane is diluted with steam and briefly heated in a furnace without the presence of oxygen. Typically, the reaction temperature is very high, at around 850 °C, but the reaction is only allowed to take place very briefly.
