metathesis catalyst
A technology for metathesis catalyst and oxide, which is used in metathesis reaction to produce hydrocarbons, physical/chemical process catalysts, metal/metal oxide/metal hydroxide catalysts, etc. It can solve the problems of low catalyst disproportionation activity and achieve good disproportionation activity. , the effect of improving life expectancy and conversion rate

Embodiment 1
[0035] 51.9986 grams of chromatographic silica gel, 100 grams of silica sol (containing 40% by weight of silicon oxide) and 2 grams of scallop powder were mixed and put into a blender, and after stirring for 12 minutes, 0.0002 gram of ammonium dimolybdate (containing 84% by weight) was added. % of molybdenum oxide), 0.0003 gram of ferric nitrate, 0.0001 gram of sodium oxide, 0.001 gram of calcium oxide, 0.0004 gram of aluminum nitrate and 10 gram of ammonium metatungstate (containing 80% by weight of tungsten oxide), and then add 250 grams of tungsten after stirring for 5 minutes Deionized water, kneading for 2 hours, extruding, drying at 100°C for 4 hours, and calcining at 550°C for 4 hours in air atmosphere to obtain the catalyst, which is designated as SL-1.
[0036] 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% 2-butene ...
Embodiment 2
[0038] 51.9977 grams of chromatographic silica gel, 100 grams of silica sol (containing 40% by weight of silicon oxide) and 2 grams of scallop powder were mixed and put into a blender, and after stirring for 12 minutes, 0.002 gram of ammonium dimolybdate (containing 84% by weight) was added. % of molybdenum oxide), 0.0003 gram of ferric nitrate, 0.0001 gram of sodium oxide, 0.001 gram of calcium oxide, 0.0004 gram of aluminum nitrate and 10 gram of ammonium metatungstate (containing 80% by weight of tungsten oxide), and then add 250 grams of tungsten after stirring for 5 minutes Deionized water, kneading for 2 hours, extruding, drying at 100°C for 4 hours, and calcination at 550°C for 4 hours in air atmosphere to obtain the catalyst, which is designated as SL-2.
[0039] The evaluation conditions of the catalyst are the same as in Example 1, and the evaluation results are shown in Table 1.
Embodiment 3
[0041] 51.4987 grams of chromatographic silica gel, 100 grams of silica sol (containing 40% by weight of silicon oxide) and 2 grams of scallop powder were mixed and put into a blender, and after stirring for 12 minutes, 0.59 gram of ammonium dimolybdate (containing 84% by weight) was added. % of molybdenum oxide), 0.0003 gram of ferric nitrate, 0.0001 gram of sodium oxide, 0.001 gram of calcium oxide, 0.0004 gram of aluminum nitrate and 10 gram of ammonium metatungstate (containing 80% by weight of tungsten oxide), and then add 250 grams of tungsten after stirring for 5 minutes Deionized water, kneading for 2 hours, extruding, drying at 100°C for 4 hours, and calcination at 550°C for 4 hours in air atmosphere to obtain the catalyst, which is designated as SL-3.
[0042] The evaluation conditions of the catalyst are the same as in Example 1, and the evaluation results are shown in Table 1.
