Abstract
A process for autothermal reforming of a hydrocarbon fuel to produce hydrogen for use in a fuel cell. The process requires the hydrocarbon fuel passed over a Group VIII metal catalyst on a solid support have an autoignition temperature greater than 600 degrees F., be low in sulfur content, have an aromatics+naphthenes content of less than 70 volume %, and preferably a oxygen content of below 1.8 wt %.
Claims11
A process for autothermal reforming of a hydrocarbon fuel to produce hydrogen for use in a fuel cell, comprising:
- passing a hydrocarbon fuel having an autoignition temperature of above 600 degrees F., a total sulfur content of less than 30 ppm by weight, an aromatics+naphthenes content of less than 70 volume %, and containing less than 1.8 wt % total oxygen, over a catalyst comprising a Group VII metal on a solid support, at reforming conditions, to produce an effluent comprising hydrogen;
- and
- passing at least a portion of the effluent comprising hydrogen to a fuel cell to produce electricity.
