Title
Production of high purity hydrogen by ethanol steam reforming in membrane reactor
Abstract

•Metal/DND systems studied as catalysts in ESR in traditional and membrane reactors.•Pt-Ru/DND composite has the best hydrogen performance in both of reactors.•Membrane reactor gives high purity hydrogen and increases ESR process efficiency.

Production of hydrogen in the course of ethanol steam reforming (ESR) on bimetallic Pt-Ni and Pt-Ru nanocatalysts supported on detonation nanodiamonds (DND) was studied in conventional and membrane reactors. The highest hydrogen yield and purity were achieved in the case of Pt-Ru/DND catalysts at total metal content of 0.3% and atomic Pt/Ru ratio of 9/1. It is shown that realization of ESR process in the membrane reactor with simultaneous hydrogen removal through the Pd-Ru membrane produces hydrogen of high purity, free of any other gaseous products.
