  • Polyalphaolefin having a low halide concentration and a method of manufacturing thereof
    Patent number: 7342143
    Abstract: A method for the processing of a polyalphaolefin feedstock having a concentration of organic halide to thereby yield a polyalphaolefin end-product having a low concentration of organic halide. The method includes a hydrogenation step whereby the polyalphaolefin feedstock is contacted under suitable reaction conditions with a specific hydrogenation catalyst composition that is resistant to halide deactivation. The hydrogenation catalyst comprises a noble metal on a support material comprising silica and alumina. The hydrogenated polyalphaolefin feedstock is further processed to remove the hydrogen halide produced during the hydrogenation step to yield the polyalphaolefin end-product.
