Kinetic Study of the Catalytic Partial Oxidation of Synthetic Diesel over 5 wt % Ni/Ce0.5Zr0.33Ca0.085Y0.085O2‑δ Catalyst for Hydrogen Production

The kinetics of the catalytic partial oxidation (CPOX) reforming of synthetic diesel (SD) has been studied for the first time for the production of hydrogen using a conventional reactor and standard liquid feed delivery system over a novel 5 wt % Ni/Ce0.5Zr0.33Ca0.085Y0.085O2‑δ (5N/CZCaY) catalyst prepared by a surfactant-assisted route. The experimental runs were conducted at atmospheric pressure, in the temperature range of 1123–1223 K, with an oxygen/synthetic diesel (O2/SD) molar ratio in the range of 6.7–9.3 and a weight of catalyst/synthetic diesel molar flow ratio (W/F SD,0) in the range of 5.28–13.21 kgcatalyst h kmolSD –1. The experimental results were used to develop a power law rate model of the form (−r SD) = 3.22 × 1015 exp(−16000/RT)N SD 2 N O2 0.5, which yielded an average absolute deviation (AAD) of
