Heat and mass transfer characteristics in a reforming catalyst bed have been experimentally investigated. Experiments were carried out with a single bench-scaled reforming tube, which was filled with reforming catalyst. The tube wall was uniformly heated, and a mixture between steam and methane or propane was reformed through the catalyst bed. Most part of the reaction was completed in the upper part of the tube. The effects of space velocity, steam carbon molar ratio, wall temperature, bed temperature, and catalyst particle diameter on the transport phenomena with chemical reactions were determined. A correlation for heat transfer coefficient was determined by Nu, Re_p, Pr, d_p/d_i, and Da. The prediction of overall methane conversion rate was also presented.
