Comparison of Ethylene Glycol Steam Reforming Over Pt and NiPt Catalysts on Various Supports

Original Paper

Abstract

Steam reforming of ethylene glycol (EG) was studied on Pt and NiPt catalysts supported on γ-Al2O3, TiO2, and carbon. On all supports bimetallic NiPt catalysts show higher activity for H2 production than the corresponding Pt catalysts as predicted from model surface science studies. The kinetic trends are similar for all catalysts (Pt and NiPt) with the H2 production rate being zero-order and fractional order with respect to water and ethylene glycol, respectively. Slight differences in selectivity to minor products are observed depending both on active metal and support. On γ-Al2O3, NiPt shows higher H2 and less alkane formation than Pt. TiO2 supported catalysts show increased water-gas shift activity but also increased selectivity to alkane precursors. NiPt/C is identified as an active and selective catalyst for EG reforming.
