Low temperature selective methane activation to alkenes by a new hydrogen-accumulating system

Abstract

A heterogeneous hydrogen-accumulating system containing porous titanium with 0.4 wt% Ni combined with high-purity titanium chips was tested for methane activation; methane conversion to C₁–C₄ hydrocarbons reached a value of ca. 20% over this material, working at 450 °C and 10 atm, after methane circulation across the system for 22 h; the split hydrogen was accumulated as TiH₂, being in solid solution with porous metallic titanium.
