Abstract
The influence of platinum additives on the properties of rhodium catalysts in the processes of steam reforming and autothermal reforming of diesel fuel was investigated. It was found that Rh/CZF was more active compared to the bimetallic sample Rh–Pt/CZF: the degree of fuel conversion in its presence was higher, and the concentration of reaction by-products was lower. The proposed two-zone Pt/CZF + Rh/CZF structured honeycomb catalyst demonstrated stable performance and high activity in the 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 results obtained are of practical significance in the development of efficient systems for the conversion of heavy hydrocarbons into synthesis gas.
