Cracking Of Petroleum-Meaning And Types Of Cracking

WebAug 1, 2012 · Qing et al. (2011) studied the kinetics of propane dehydrogenation, cracking and coke formation over Pt–Sn/Al 2 O 3 catalyst, assuming same activity for all sites. The distinction of active sites as different types has also been proposed in the literature ( Kumbilieva et al., 2006 ). WebThe catalytic cracking process of propane into ethylene and methane involves two steps. The calculated reaction energies reveal that the first step is the rate determining one, because the corresponding energy barrier is ~100 kJ/mol higher compared to the second step. This finding is in accordance with literature date.
