In this work, hydrogen is produced from bio mass derived glycerol by steam reforming process over Ni/Al2O3 catalyst with low methane and carbon monoxide formation. Experiments were conducted in a tubular fixed-bed flow reactor over a temperature range of 650oC - 700oC and 1atm pressure, feed concentrations up to 40 wt% glycerol and water to glycerol molar ratio (WGMR) of 9:1 are the best conditions for hydrogen production. Thermo dynamically under this conditions coke formation will be inhibited and methane production is minimized. Glycerol was completely gasified to hydrogen, carbon dioxide, and methane along with small amounts of carbon monoxide. At dilute feed concentrations, near-theoretical yield of 7 mol of hydrogen/mol of glycerol was obtained, which decreases with an increase in the feed concentration. Water gas shift reaction, further converts CO into CO2 and H2. X-ray diffraction and electron microscopy were used to study the crystal structure, and morphology of the catalysts. The catalysts studied Ni/Al2O3 gives the maximum yield in which nickel is in interacted form and the best operating conditions for Ni/Al2O3 are 7000 C and 120 ml/hr of feed rate.
