摘要：NOVELTY - An alpha -olefin oligomerization solid supported catalyst comprises balance gamma -alumina loaded with aluminum trichloride as carrier, and 11.16-18.72 wt.% transition metal. The aluminum trichloride comprises 3.07-5.23 wt.% aluminum and 11.16-18.72 wt.% chlorine. The metal is from sulfate or nitrate salt of iron, cobalt, nickel, zinc or copper. USE - An alpha -olefin oligomerization solid supported catalyst. ADVANTAGE - The catalyst reduces catalyst consumption, is environment-friendly, reduces corrosion of device, and has kinematic viscosity of 13.65-25.05 cSt at 100 degrees C, high solid reaction efficiency, viscosity index of 138-161 and conversion rate of 61.2-77.8%. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: (1) a method of preparing an alpha -olefin oligomerization solid supported catalyst comprising impregnating gamma -alumina with 0.5-3 M transition metal sulfate or nitrate salt solution for 1-8 hours, vacuum drying at 200-800 degrees C for 2-12 hours in the presence of inert gas, mixing 5-15 g aluminum chloride and 150 ml organic solvent, diluting with water, adding 15 g vacuum dried product, reflux heating for 6-24 hours, filtering, washing the filter cake with organic solvent, and vacuum drying; and (2) a method of catalytic oligomerization reaction comprising oligomerizing 1-decene at 80 degrees C and pressure of 1 MPa for 3 hours in the presence of the alpha -olefin oligomerization solid supported catalyst, filtering distilling at normal pressure, and decompressing to obtain 1-decene oligomer.
