Production of ultra highly pure H2 and higher hydrocarbons from methane in one step at mild temperatures and development of the catalyst under non-equilibrium reaction conditions

Abstract

Ultra highly pure hydrogen and more valuable hydrocarbons are produced directly from methane in one step beyond the thermodynamic equilibrium conversion by integration of the dehydrogenation reaction and hydrogen separation with a Pd–Ag based membrane reactor at mild temperatures, and a highly active catalyst is developed under the non-equilibrium reaction conditions.
