Organic chemical hydride dehydrogenation over nickel catalysts supported with SiO₂ for hydrogen recovery

ABSTRACT

Dehydrogenation of organic chemical hydrides has been investigated with catalysts in which the economical Ni was adopted as catalytic component and SiO₂ as support. In this work dehydrogenation of methylcyclohexane was performed as organic chemical hydride in a fixed-bed catalytic reactor in the temperature range of 653–713 K, having 5, 10, 15, and 20 wt.% Ni content.
