Transformation of methylcyclopentane over Ir/Al2O3 and n-hexane over Pt-black. Interpretation of hydrogen control

Abstract

Hydrogen sensitivity of MCP ring opening on Ir/Al₂O₃ and that of n-hexane transformation on Pt black have been investigated. Comparison of the results on O₂–H₂-treated and ‘carbon’-precovered catalysts confirms that in the interpretation of the hydrogen effect on product distribution one has to regard the steric/electronic effect of trapped hydrocarbons on the surface metal atoms.
