Abstract: Mo_２ C／β zeolite catalysts were prepared using temperature － programmed reduction method with MoO_３ as precursor and modified β zeolite as carrier and characterized by XRD and TEM． The effects of reduction conditions on the catalyst performance were investigated．Hydrogenation of soybean oil was carried out in small fixed bed reactor．The results show that with temperature programming rate decreased ， the diffraction peak intensity of β － Mo_２ C increased． With the final carbonization temperature increased ，carbonation level gradually deepened ．When the temperature programming rate of 1 ℃ ／
min and final temperature of carbonization of650 ℃ ，β － Mo_２ C diffraction peak was moet clearest ．With hexane as carbon source ，Mo_２ C uniformly dispersed on the carrier ，with a high surface area ．Using Mo_２ C ／ β zeolite Loading 21.25%Mo₂ C as catalyst ，under the condition of reaction pressure 3.5 MPa ， space velocity 0.5 h^{－ １}，volume ratio of hydrogen to oil 500，reaction temperature 280 ℃ and320 ℃ ，The pour point of hydrogenated soybean oil decreased down to －5～-10 ℃ and the cetane number kept more than 70.
