Hydroxyapatite-supported tri-metallic catalyst for hydrogen production from steam reforming of glycerol

Glycerol is a byproduct of biodiesel industry that has high economic value to produce hydrogen as an energy source. the selection of catalyst support for active metal catalyst in hydrogen production is a major concern since it affects the activity of metal catalyst during the steam reforming process of glycerol. besides that,bio-based material as catalyst support provides attractive choice as it is more environmentally friendly. in this study,hydroxyapatite (hap) as support material for tri-metallic catalyst ni-ce-cu was prepared using deposition-precipitation method and used in steam reforming reaction of glycerol to produce hydrogen. the catalyst prepared was characterized by bet,fe-sem,edx,and tem. the catalytic activity tests were conducted at atmospheric pressure and temperatures between 400 – 600 °c in a tubular micro-reactor. glycerol-water ratios used were 1:4,1:8,and 1:16. it was found that the highest hydrogen yield (55.0%) was obtained at temperature of 600 °c and glycerol-water ratio of 1: 8 with glycerol conversion of 94.0%. © 2016 penerbit utm press. all rights reserved.
