Preparation of Ni Loaded on Zeolite and its Application for Conversion of Glycerol to Hydrogen

Glycerol is the main by-product of biodiesel production and during the trans-esterification reaction, about 10 wt % of glycerol is produced. In this study, different amount of Ni was loaded on HZSM-5 and tested for the conversion of glycerol to hydrogen. The studies were also conducted at different reactor temperature of 450, 500, 550, 600 and 650°C respectively. The structural characterization of the catalyst was carried out using the XRD. It was found that, the addition of 15 wt % of nickel loaded on HZSM-5 shows the highest glycerol conversion of 98.54%. In addition, it produces the highest yield of hydrogen gas operated at reactor temperature of 600°C.
