Abstract

The influence of platinum additives on the properties of rhodium catalysts in steam and autothermal reforming processes of diesel fuel was investigated. It was found that the Rh/CZF catalyst exhibited higher activity, with a higher degree of fuel conversion and lower production of side reaction products compared to the bimetallic Rh–Pt/CZF catalyst. The proposed two-zone catalytic Pt/CZF+Rh/CZF structured honeycomb catalyst demonstrated stable performance and high activity in autothermal reforming of commercial diesel fuel. However, the presence of platinum in the frontal zone of the catalyst reduced its resistance to coking compared to the rhodium-containing sample. The obtained results are of practical significance in the development of efficient systems for the conversion of heavy hydrocarbons into synthesis gas.
