Embodiment 1
[0036] Embodiment 1: a kind of method of atmospheric pressure plasma synergistic catalytic benzene hydrogenation to prepare cyclohexane
[0037] The method for preparing cyclohexane through the synergistic catalysis of benzene hydrogenation by atmospheric pressure plasma of the present invention, the detailed steps of the preparation method are as follows:
[0038] a. Preparation of metal oxide catalyst: Weigh nickel nitrate Ni (NO 3 ) 2 , adding water to make a molar concentration of 0.5 mol·L -1 The solution, according to the ratio between the diatomite and the prepared nickel nitrate solution is 1g: 10ml, take by weighing the catalyst carrier diatomite, dipping the diatomite into the prepared nickel nitrate solution, dipping 10h, take out after the dipping Drying (drying temperature is 100°C, drying time is 6h), after drying, it is placed in a muffle furnace for roasting, roasting temperature is 500°C, roasting time is 4h, and metal oxide catalyst is obtained after roasti...
Embodiment 2
[0044] Embodiment 2: It is basically the same as Embodiment 1, except that:
[0045] In step a: take by weighing nickel nitrate Ni (NO 3 ) 2 , adding water to make a molar concentration of 0.6 mol L -1 solution, the ratio between diatomite and the prepared nickel nitrate solution is 1g:8ml, the dipping time is 14h, after dipping, take out and dry (drying temperature is 120 ° C, drying time is 5h), roasting temperature The calcination time was 650°C, the calcination time was 2h, and the calcined metal oxide catalyst was placed in hydrogen plasma and reduced for 45min;
