This document summarizes an experimental study on H2 production from steam reforming of glycerol using different catalysts. The study tested various nickel-based catalysts under conditions of 650°C calcination temperature, 700°C reduction temperature, 600°C reaction temperature, 6:1 steam-to-carbon ratio, and 1 atm pressure. The results show product distribution and stability over time for the different catalysts, with 5Ni/Al and 5Ni/Ce performing best in terms of stable H2 production.
