Dodecane, one of the main components in kerosene, was used as a model material to investigate reactions in a palladium membrane reactor for steam reforming of kerosene. The influence of pre-reforming on the performance of the membrane reactor was investigated. A decrease in hydrogen yield caused by coke formation was suppressed through pre-reforming by lowering the concentration of olefins, aromatics and unreacted dodecane in the feed to the membrane reactor. In addition, the proportion of total hydrogen production that permeated the membrane was clearly higher with pre-reforming compared with that without pre-reforming. Pre-reforming prevented deactivation of both the catalyst and the membrane, resulting in efficient separation of hydrogen from the reaction field and therefore achieving a higher hydrogen yield.
