Embodiment 1
[0037] 51.999 grams of chromatographic silica gel, 100 grams of silica sol (containing 40% by weight of silicon oxide) and 2 grams of turnip powder were mixed and put into a blender, and after stirring for 20 minutes, 0.003 grams of titanium tetrachloride and 10 grams of partial Ammonium tungstate (containing 80% by weight of tungsten oxide), after stirring for 5 minutes, add 250 grams of deionized water, knead for 2 hours, extrude and dry at 100°C for 4 hours, and bake at 550°C for 4 hours in air atmosphere The obtained catalyst is denoted as SL-1.
[0038] The evaluation of the catalyst was carried out on an olefin disproportionation evaluation device, using 2-butene and ethylene as raw materials, calculated by mass fraction, the raw materials were 99.9% of 2-butene and 99.9% of ethylene. The reaction is at a temperature of 300°C, a pressure of 3MPa, a molar ratio of ethylene to butene of 3.5 and a weight space velocity of 2-butene of 8 hours -1 The evaluation was carried o...
