Abstract

The invention discloses a supported metallocene. The supported metallocene comprises a polystyrene microsphere and metallocene supported on the polystyrene microsphere; the supported metallocene comprises the following elements in percentage by weight: 1%-2.3% of nitrogen, 11.6%-12.9% of halogen, 6.6%-16% of zirconium and the balance of carbon and hydrogen. The active components of the supported metallocene are bonded on the polystyrene microspheres through chemical bonds, so that the supported metallocene catalyst is good in loading stability, low in loss rate of the active components and long in service life; meanwhile, the supported metallocene has relatively high catalytic activity, and the selectivity of high-carbon olefins of C12 or above is high.

Description

technical field [0001] The present invention relates to a supported metallocene, a catalyst containing the same and its preparation and application. Specifically, it is a metallocene catalyst for preparing solvent oil by oligomerization of butene. Background technique [0002] Mixed butenes are oligomerized to generate C8-C20 iso-olefins, which can be hydrogenated to produce isoparaffin solvent oil. Synthetic isoparaffin solvent oil is a special oil that does not contain sulfur, aromatic hydrocarbons and other harmful substances and has no peculiar smell. It can be used as a solvent for the production of coatings, pesticides, inks and other products. At the same time, it can also be used as the base oil of low melting point lubricating oil. where C 16 and C 20 It is a high-value solvent oil that is used in ink solvents and other uses such as high-carbon hydrocarbons. A large amount of butene can be obtained from the ethylene cracking process of petroleum refining and th...
