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 �C were proposed. The optimized design was predicted to
increase the conversion from approximately 32e74%. The model could be in general used
for designing any endothermic heterogeneous catalytic reaction in a spray pulse reactor
