Behaviors of Mo-Ni-P-H/Si/Al for hydrogenation of poly α-alkene derived base oil

以水玻璃低温膨胀负载硅和铝作为载体,先通入空气、后浸入Mo-Ni-P-H,制得催化剂,用于催化聚α-烯烃基础油加氢反应。结果表明,在反应温度280℃、氢压6.0 MPa、空速0.5 h-1和氢油体积比为700∶1条件下,加氢效果较理想,溴值为0.18 g.(100g)-1,残炭质量分数为0.011%,硫含量0.38μg.g-1,比色<0.5,运动黏度几乎没有损失。聚α-烯烃合成基础油的性能有较大提高。

Using Si-Al, supported on water glass by low temperature expansion, as the support, a catalyst was prepared by first introducing air flow and then impregnating the support in Mo-Ni-P-H, and used in α-alkene base oil hydrogenation. Agreeable hydrogenation results were obtained under reaction temperature of 280 ℃, hydrogen partial pressure of 6.0 MPa, LHSV of 0.5 h - 1 and V（hydrogen） ： V（oil） of 700： 1, with bromine value of 0.18 g. （100g-oil）^-1, residual carbon of 0.011% （mass fraction）, sulfur content of 0.38 μg.g^-1, chroma of 〈 0.5 and little loss of kinematic viscosity. Properties of the poly α- alkene derived lube base oil were greatly improved.
