Catalytic Cracking of Cycloparaffins Admixed with Olefins: 2. Single-Event Microkinetic (SEMK) Assessment

摘要: The developed SEMK model is used to provide an insight into the contribution of individual reactions in cracking methylcyclohexane as well site coverage by various carbenium ions. preferred reaction pathways for conversion are hydride transfer followed PCP-isomerizations, deprotonation and en- docyclic β-scission, accounting 61%, 22% 12% its disappearance, respectively, at 693 K 30% methylcyclohexane. Protolysis plays a minor role Once cyclic diolefins formed, all them can be instantaneously transformed aromatics, which easily interconverted via disproportionation. Judg- ing from ion concentrations it evident that, investigated operating conditions, less than 5% acid sites covered ions, 2% corresponds type species including allylic ones.
