摘要：

The hydrogenolysis of methylcyclopentane (MCP) has been used as a test reaction to analyze geometric and promoting effects in Pt catalysts supported on alkaline L zeolites. It has been observed that the production of 3-methylpentane (3MP) over these catalysts is significantly higher than over other Pt catalysts. Based on the micro-geometry of the system, we propose that collimating (geometric) effects play an important role in hydrocarbon reactions on these catalysts. On the other hand, the increased activity exhibited by the KL zeolite-supported catalysts relative to SiO2-supported catalysts might indicate that promoting effects are also operative.
