5 results about "Fischer–Tropsch process" patented technology

The preparation method comprises the following steps: by taking C9-C11 Fischer-Tropsch process mixed alpha-olefin as a raw material, premixing the raw material with an industrial-grade organic aluminum reagent, adding a three-way catalyst system formed by vinyl bisindenyl zirconium dichloride metallocene and organic boride in a one-pot manner at normal pressure for polymerization, and then adding a catalyst system formed by vinyl bisindenyl zirconium dichloride metallocene and organic boride into the pre-mixed raw material to prepare the high-viscosity poly-alpha-olefin synthetic oil. And after the reaction is finished, carrying out acid alcohol quenching, water washing and rotary evaporation to obtain a PAO product in one step. The obtained product has the kinematic viscosity of more than 200cSt at 100 DEG C, the viscosity index of more than 225 and the molecular weight distribution PDI of 1.5-2.0, has high viscosity-temperature performance and excellent shear stability, is simple and convenient in process and low in cost, and is suitable for preparing high-end lubricating base oil.
