Abstract:
The present work studied the pressure aqueous processing of glycerol (by-product of biodiesel) without external hydrogen addition to produce value-added products. A series of Ni catalysts supported on Al2O3 and Fe as promoter were prepared through co-precipitation technique by changing the Fe/Al ratio (0, 25 and 75% molar). The prepared samples were characterized by several techniques (XRD, H2-TPR, N2 adsorption and ICP-OES). All the catalysts showed a low carbon conversion to gas and high carbon conversion to liquid products mainly 1,2-propanediol, acetol and ethylene glycol. This work demonstrates the effects of the molar ratio of Fe/Al on physicochemical characteristics of Ni-Al-Fe catalysts and during the pressure aqueous processing (PAP) of glycerol to value-added products.
