Abstract

A hydrogenation method for producing polyalphaolefin synthetic oil products. The high-viscosity polyalphaolefin synthetic oil raw material and circulating oil are mixed and then sequentially enter the first hydrogenation reaction zone and the second hydrogenation reaction zone for reaction, and the reaction effluent is passed through After gas-liquid separation, the obtained liquid stream is subjected to fractionation to obtain light materials and heavy materials. The light materials are recycled to the raw material tank as circulating oil, and the heavy materials are refined polyalphaolefin synthetic oil products. The treatment method provided by the present invention improves the feeding status of the fixed-bed hydrogenation reactor, and solves the problem of partial flow of materials in the fixed-bed bed layer or incomplete hydrogenation in the fixed-bed hydrogenation reactor existing in the prior art , and obtained high-quality refined polyalphaolefin synthetic oil products.

Description

Technical field [0001] The present invention relates to a process of poly-α-olefin synthetic oil, and more specifically, a hydrogenated poly-α-olefin synthetic method of quality products. Background technique [0002] Poly-α-olefin synthetic oil (PAO) is polymerized in a catalyst Linear α-olefins, and the polymerization product was subjected to the long chain alkane configuration rules obtained by hydrotreatment. Poly-α-olefin synthetic oils of viscosity-temperature resistance, low temperature fluidity and oxidation stability are better than evaporation mineral base oil, it has become an ideal base oil, widely used in formulating lubricants and specialty grade. Poly-α-olefin synthetic oils of different varieties may be modulated diesel engine oil, gasoline engine oil, refrigerator oil, heat transfer oil, compressor oil, automatic transmission fluid and the like grease, the lubricating oil in particular under arctic conditions, can modulate a high temperature and, in many demandin...
