Example Embodiment
[0028] Example 1:
[0029] 5 grams of γ-Al modified with 10wt% titanium 2 O 3 Degas and dehydrate at 110℃ for 3 hours, then transfer to a vacuum device, maintain the vacuum between 650mmHg-750mmHg and keep it for 2 hours; weigh a certain amount of ammonium molybdate in the solvent and add it to the surface Active agent nonylphenol polyoxyethylene ether, and keep stirring until the ammonium molybdate is completely dissolved, and the amount of solvent is based on the coverage of the carrier; the solution is immersed on the carrier that has been vacuum dehydrated and degassed and kept at room temperature Dry the above-mentioned dried catalyst in a muffle furnace for calcination, grow to 500°C at a constant heating rate and keep it for 2 hours; repeat the above process to impregnate another active component cobalt nitrate; prepare the above A good catalyst is characterized in a self-made micro-reactor, and the evaluation conditions have been given in detail above. The specific charact...
Example Embodiment
[0032] Example 2:
[0033] The specific preparation process of the catalyst is the same as in Example 1, except that the amount of titanium used to modify the support is 5 wt%. The specific characterization results are shown in the following table:
[0034] Make up
[0035] Calculating from the previous formula shows that the conversion rate of thiophene is 95.89%, the conversion rate of styrene is 36.44%, and the conversion rate of cyclopentadiene is 32.91%.
Example Embodiment
[0036] Example 3:
[0037] The specific preparation process of the catalyst is the same as in Example 1, except that the surfactant sodium dodecylbenzene sulfonate is added. The specific characterization results are shown in the following table:
[0038] Make up
[0039] Calculating from the previous formula shows that the conversion rate of thiophene is 97.53%, the conversion rate of styrene is 17.89%, and the conversion rate of cyclopentadiene is 18.36%.
