WebMar 22, 2015 · SCC combines mild thermal cracking with the acid promoted cracking of a zeolite-based catalyst, and can provide very high yields of light olefins (with the possibility of varying the propylene-to-ethylene ratio) while operating at temperatures much lower than those used in the SC process [ 104 ]. WebPropylene cracking gave both ethane and ethylene, yields being compar- able with those from propane cracking. The kinetic behavior of the formation of these products was, however, complex; typical product yield-time plots are shown in Fig. 6. Thus, reactions of the type C~ -> C~ -t-C did not contribute significantly to product yields.
