Sensitivity Analysis of High-Pressure Methanol—Steam Reformer Using the Condensation Enthalpy of Water Vapor

A methanol–steam reformer (MSR) can safely provide hydrogen-rich fuel for a cell system. Since the operating temperature of an MSR is relatively low, convective heat transfer typically used to thermal energy endothermic reactions in MSR. In this study, use phase change was investigated, which enhanced uniformity longitudinally along ANSYS Fluent® software investigate performance reforming reactions. comparative analysis using sensible and latent as supply sources performed. Using source achieved lesser drop than that under 5.29 K outer pipe. Moreover, sensitivity methanol–steam-reforming terms carbon ratio, gas hourly velocity (for inner pipes MSR), inlet (inner pipes), reactor length, pressure pipe) When water vapor used, wall conveniently controlled uniformly distributed channel (standard deviation: 0.81 K). Accordingly, methanol conversion rate uses ~4% higher employs transfer.
