Description
Technical Field
The invention relates to a preparation method of saturated metallocene poly alpha-olefin.
Background
Poly-Alpha-Olefins (PAO) is a fully synthetic hydrocarbon lubricant base oil prepared by a chemical synthesis method, has the advantages of high viscosity index, excellent low-temperature performance, good thermal oxidation stability, low volatility, good shear stability and the like, and is currently considered to be the most potential fully synthetic lubricant base oil. PAO is usually polymerized by conventional catalysts such as Lewis acid or Ziegler-Natta catalysts, e.g. using BF 3 Catalytic preparation of low viscosity PAO using AlCl 3 Catalytic preparation of medium viscosity PAO high viscosity PAO was prepared using Ziegler-Natta catalyst catalysis. And the metallocene poly alpha-olefin (mPAO) is a product which is obtained by catalyzing alpha-olefin polymerization by a metallocene catalyst and has a comb structure and no upright side chain. Such structures affect PAO product performance and mPAO generally possesses improved rheological and flow characteristics, providing better shear than conventional PAOsShear stability, lower pour point and higher viscosity index, has good viscosity-temperature characteristics. These characteristics determine that the mPAO can be used in high severity environments, including power transmission and gear oils, compressor lubricating oils, transmission fluids, and industrial lubricating oils. Along with the increasing requirements of society on energy utilization rate and ecological environment protection, the demand of people on high-performance mPAO lubricating oil base oil is increased.
The mPAO prepared by catalyzing alpha-olefin with metallocene compound has double bond in the structure. In order to improve the oxidation resistance of the mPAO, the mPAO must be hydrogenated to saturation.
CN105008409B discloses a process for producing an alpha-olefin polymer and a hydrogenated alpha-olefin polymer. The addition of hydrogen during polymerization is disclosed therein. The addition of hydrogen during the polymerization process tends to cause problems with the saturation of the feed. Although it discloses the hydrogenation of the prepared alpha-olefin polymer, no specific hydrogenation scheme is disclosed.
CN104370675B discloses a process for preparing polyalphaolefins in a continuous manner, but it requires the addition of an additional catalyst, for example 17 thereof, to which 0.5 wt% (based on the total weight of polyalphaolefin to be hydrotreated) of basf Ni-5249 catalyst is added, hydrogen is introduced thereto until the hydrogen pressure is 4.0MPa, the reaction vessel is heated to 200 ℃ and reacted at this temperature for 3 hours. By means of hydrogenation catalysts, such as nickel, equipment investment and raw material costs are increased.
To sum up, at present, there are two main methods for hydrogenating saturated mPAO, namely, hydrogenation catalyst such as nickel or other noble metal inorganic substances is used for carrying out fixed bed or kettle hydrogenation; in the other, hydrogen is added to regulate the molecular weight during the polymerization process, and saturated mPAO is prepared. The former hydrogenation process increases equipment investment and raw material costs, and the latter tends to cause raw materials to be saturated. For this reason, it is necessary to find an economical way to hydrogenate saturated mPAO.
