SSZ-13 supported Ir as an efficient catalyst for methylcyclopentane ring-opening reaction

Abstract

Ir/H-SSZ-13 catalysts were used for methylcyclopentane (MCP) ring-opening (RO) reaction, and exhibit higher yields to RO products than H-ZSM-5, H-USY and Al2O3 supported Ir catalysts. Ir species supported on H-SSZ-13-A (about 200 nm) exhibits higher activity than those on H-SSZ-13-B (about 8 μm) due to its more accessible acid sites. Ir/H-SSZ-13-A gives higher reactivity than Ir/Al2O3, especially in the case of low Ir loading because of the promotion of the strong acid sites located on the external surface of H-SSZ-13-A. This work demonstrates that SSZ-13 supported metal is a potential catalyst for RO reaction.
