Embodiment 1
[0032] A preparation method for iron-peat-supported iron-zinc-copper catalyst, comprising the following steps:
[0033] Preparation of iron peat pellets:
[0034] Take 1-2L of iron sludge from a paper mill in Shaanxi, wash it with distilled water to remove surface impurities, filter it, and then granulate the iron sludge with a particle size of 0.8mm. After the granulation is completed, dry it in an oven at 110°C, and then put it in nitrogen Roast at a high temperature within the range of 500°C for 3 hours in the atmosphere, and cool to room temperature to obtain iron peat particles.
[0035] Preparation of iron-peat-supported iron-zinc-copper catalyst:
[0036] Get 10g of the iron peat particle carrier obtained above in a 250mL beaker, add 150mL containing 2.5% FeSO 4 , 1.5% ZnSO 4 , 1.5% CuSO 4 Put the mixed solution of the mixed solution into the shaker and shake it under the conditions of 25°C and 200r / min for 20h. After shaking and soaking, wash off the active compone...
Embodiment 2
[0038] A preparation method for iron-peat-supported iron-zinc-copper catalyst, comprising the following steps:
[0039] Preparation of iron peat pellets:
[0040] Take 1-2L of iron sludge from a paper mill in Shaanxi, wash it with distilled water to remove surface impurities, and then filter it with suction, then granulate the iron sludge with a particle size of 1.2mm. Roast at a high temperature within the range of 700°C for 2 hours in an air atmosphere, and cool to room temperature to obtain iron peat particles.
[0041] Preparation of iron-peat-supported iron-zinc-copper catalyst:
[0042] Get 10g of the iron peat particle carrier obtained above in a 250mL beaker, add 150mL containing 3% FeSO 4 , 2% ZnSO 4 , 2% CuSO 4 Put the mixed solution of the mixed solution into the shaker and shake it under the conditions of 25°C and 200r / min for 20h. After shaking and soaking, wash off the active components not loaded on the surface with distilled water, and then filter with suct...
Embodiment 3
[0044] A preparation method for iron-peat-supported iron-zinc-copper catalyst, comprising the following steps:
[0045] Preparation of iron peat pellets:
[0046] Take 1-2L of iron sludge from a paper mill in Shaanxi, wash it with distilled water to remove surface impurities, and then filter it, then granulate the iron sludge with a particle size of 1.0mm. After the granulation is completed, dry it in an oven at 110°C, and then put in nitrogen Roast at a high temperature within the range of 600°C for 2.5 hours in the atmosphere, and cool to room temperature to obtain iron peat particles.
[0047]Preparation of iron-peat-supported iron-zinc-copper catalyst:
[0048] Get 10g of the iron peat particle carrier obtained above in a 250mL beaker, add 150mL containing 2.5% FeSO 4 , 1.5% ZnSO 4 , 1.5% CuSO 4 Put the mixed solution of the mixed solution into the shaker and shake it under the conditions of 25°C and 200r / min for 20h. After shaking and soaking, wash off the active comp...
