摘要
Polymer electrolyte membrane (PEM) fuel cells require hydrogen as the fuel source for generating power. Hydrogen can be produced in a fuel processor by the catalytic reforming of hydrocarbons. The objective of this paper is to present an analysis of the autothermal reforming (ATR) of synthetic diesel fuel in an adiabatic reactor using a Pt/ceria catalyst. ATR combines endothermic steam reforming and exothermic partial oxidation reactions in a single unit. This simple system provides higher efficiency and higher energy density than other conventional processes. The product composition as a function of the operating variables and the temperature and concentration profile inside the reactor were studied. Hydrogen was generated under adiabatic conditions by heating the feed mixture and ATR reactor to only 400 degrees C in contrast to higher temperatures reported in the literature. The stability of the catalyst and its response to the presence of S poison was also investigated. (c) 2005 Elsevier B.V. All rights reserved.
