EFFECTS OF GASOLINE COMPONENTS ON FUEL PROCESSING AND IMPLICATIONS FOR FUEL CELL FUELS

摘要

This work indicates that all of the major types of chemicals found in gasoline (straight chain and branched paraffins, napthenes, and aromatics) can be autothermally reformed to provide a hydrogen-rich gas. Of the components tested, trimethylbenzene required the most severe reforming conditions, both high temperature (800℃) and low space velocities. This suggests that a gasoline without trimethylbenzene would lead to higher overall efficiency and may allow for smaller catalyst beds operating at lower temperatures. The effects of sulfur impurities on the catalyst are dependent on the catalyst. Sulfur appears to improve the hydrogen yield for Pt-containing catalysts but appears to reversibly poison Ni-containing catalysts. There was no major long-term degradation caused by adding unsaturated components or sulfur to the fuel.
