A low-cost Ni-B alloy catalyst was prepared by chemical reduction method and used for partialhydrogenation of fatty acid methyl esters. The conditions for catalyst preparation, including Ni to B ratio, pH of NaBH4 solution, types and quantity of metal modifiers were optimized. Ni-La-B, prepared by modificationof Ni-B with La, showed significantly high catalytic partial hydrogenation activity. The optimum texturalproperties (small particle size, high specific surface area and well-defined pore structure) and electronenrichment of active Ni sites were the favorable factors for the high hydrogenation activity of Ni-La-Bcatalyst, which showed reasonable stability in catalyst recycle experiments.
