Propane cracking reaction

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.

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.

WebDespite such processes, currently more research is focused on developing alternatives such as oxidative dehydrogenation (ODH) for two reasons: (1) undesired reactions take place at high temperature leading to coking and catalyst deactivation, making frequent regeneration of the catalyst unavoidable, (2) it consumes a large amount of heat and … WebAug 25, 2024 · In the absence of UV light, cyclopropane can undergo addition reactions in which the ring is broken. For example, with bromine, cyclopropane gives 1,3-dibromopropane. This can still happen in the presence of light - but you will get substitution reactions as well. The ring is broken because cyclopropane suffers badly from ring strain.
