The Design of a Small Endothermic Generator for Laboratory Use
The design and performance testing of a small, electrically heated, endothermic generator using propane is described. The generator is used at the undergraduate and graduate level as a teaching tool and for research. Construction of the generator is detailed. Performance comparisons to a mathematical model of a packed bed is reported. A parametric analysis of operating variables (operating temperature, fuel to air mixture, flow rate, catalyst size, and non-reactive alumina topping) was performed and results provided. Results of the analysis indicated that operating temperatures at least 1,950 F, with an air to propane ratio of 7.6:1, and small catalyst without alumina topping provided the best performance. It was found that the alumina topping contributed to a high exit temperature, but caused a premature sooting reaction at the exit end of the retort.
