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.

WebMar 15, 2012 · Propane cracking reaction is a competitive reaction with dehydrogenation reaction over Brønsted acid sites. Different from the dehydrogenation reaction, the cracking reaction involves the cleavage of C–C bond rather than the cleavage of C–H bond [53]. Scheme 1 c depicts the reaction route of the cracking reaction. Webcracking of ethane This reaction provides one of the ways to get ethane from ethane. Similarly, the pyrolysis of propane and butane gives us a variety of products. Cracking of …
