No deactivated production of hydrogen by pyrolysis of ethane over graphite-based catalysts using membrane-type reactors

Abstract

A system consisting of a graphite catalyst and an Ag-Pd membrane reactor was found to be effective for ethane decomposition to hydrogen and carbon, where the H₂/C ratio was approximately 1.5, in accordance with the stoichiometric ratio; catalyst deactivation was not observed during reaction, since the graphite-like carbons produced by the reaction, probably also catalyze the reaction in the temperature range of 800–1000 K.
