Hydride transfer(htr) is generally recognized as one of the most important elementary reactions in catalytic cracking. Using Single Event Micro Kinetics (SEMK) in the assessment of the catalytic cracking of aliphatics, the autocatalytic character of hydride transfer was addressed at the molecular level. The results showed that the presence of 1 octene in the feedstock resulted in the enhanced acid site coverage, in particular at lower feed conversions and, consequently, in higher hydride transfer rates. Irrespective of the co feeding of olefins, hydride transfer rates towards tertiary carbenium ions were almost 5 orders of magnitude higher than those towards secondary ones. The investigation of the Cracking Mechanism Ratio (CMR) and the reaction cycle Chain Length (CL) reveals that both CMR and CL adopt similar values when a pure paraffin feed is processed. However, while CMR was strongly affected by the addition of olefins in the feedstock, CL remained practically constant.
