PRELIMINARY PROCESS STUDIES ON THE GENERATION OF HYDROGEN FOR SMALL FUEL CELL SYSTEMS
Abstract
Alternate generation and purification systems were evaluated to determine the most suitable combination f r making pure H from liquid hydrocarbons to supply small fuel-cell power plants. Preliminary designs were made for 2000 and 50 standard cubic feet per h ur (SCFH) CAPACITY UNITS AND THERMAL EFFICIE CIES, WEIGHTS, VOLUMES, AND OPERATING REQUIREMENTS DETERMINED. An analysis of thermal losses was made for each plant. It was concluded that steam reforming followed by water-gas shift was best suitegeneration and purification systems were evaluated to determine the most suitable combination f r making pure H from liquid hydrocarbons to supply small fuel-cell power plants. Preliminary designs were made for 2000 and 50 standard cubic feet per h ur (SCFH) CAPACITY UNITS AND THERMAL EFFICIE CIES, WEIGHTS, VOLUMES, AND OPERATING REQUIREMENTS DETERMINED. An analysis of thermal losses was made for each plant. It was concluded that steam reforming followed by water-gas shift was best suited as a generation system under all circ mstances considered in this study but purification methods were greatly influenced by capacity. Feed desulfurization is essential for the 2000-CFH plant requirements but might well be eli inated at the 50-CFH level. The use of a Pd diffuser for obtaining pure H is highly desirable for the smaller plant and may also be so at the 2000 CFH level. The use of monoethanolamine absorption to remove CO2 followed by conversion of CO to methane is practical for the larger plant but not for the smaller. The procedures and controls required for start-up, shut-down and normal plant operation are described. Constant o erator attendance is required during the first 2 operations while moderate supervision will suffice during the normal operating period. (Author)
