摘要：

A mathematical model has been developed to study the impact of nozzle-catalyst distance and bulk gas temperature on the conversion and hydrogen evolution rate in a spray pulse reactor. The effects of reactor configuration and operating parameters on conversion and evolution rate were predicted with more than 90% accuracy. Reactor optimization and sensitivity analysis were carried out and an optimal design of nozzle-catalyst distance 5 cm and bulk gas temperature of 50 degrees C were proposed. The optimized design was predicted to increase the conversion from approximately 32-74%. The model could be in general used for designing any endothermic heterogeneous catalytic reaction in a spray pulse reactor. Copyright (C) 2014, Hydrogen Energy Publications, LLC.
