Abstract
. The heat and mass transfer performances of the steam reforming of toluene (SRT) in a solar thermochemical reactor (STR) were numerically investigated. A mathematical model is developed to simulate the heat and mass transfer processes coupled with thermochemical reaction kinetic in STR with radiative heat loss. The effect of several parameters including the superficial velocity (Vsg), operating time (ti) and operating temperature (Top.) were investigated. As results, when the Vsg is increased, the temperature profiles of the gas phase are remarkably decreasing. The reactant mole concentration (C7H8 and H2O) distributions decrease sharply along the STR length. On the other hand, product mole concentration distributions (hydrogen) increase remarkably along the STR length. According to simulated results, the overall conversions of C7H8 reach the maximum value of 94.58% at the operating time of 3.0 hours
