Embodiment 1
[0033] The preparation method of the present embodiment catalyst carrier comprises the following steps:
[0034] Step 1. Add 990g of white carbon black and 10g of silicon carbide into the wheel mill and mix well, then dilute 50g of water glass with a modulus of 3.3 with 1900g of water, add them to the wheel mill in batches and mix for 60min, take out The mixture was obtained after standing for 60 minutes, and then the mixture was placed in a twin-screw extruder for extruding to obtain a cylindrical shaped body with a diameter of 3.5 mm; the white carbon black was prepared by a precipitation method;
[0035] Step 2. Dry the molded body obtained in Step 1 at 150°C for 4 hours, then place it in a muffle furnace, and heat it up to 400°C for 120 minutes in an air atmosphere at a rate of 5°C / min to obtain a catalyst carrier.
[0036] The binder in this embodiment can also be water, clay, kaolin, paraffin, gum, starch paste, silica sol, aluminum sol, nitric acid solution or phosphori...

[0042] The preparation method of the present embodiment catalyst carrier comprises the following steps:
[0043] Step 1. Add 950g of white carbon black and 50g of silicon carbide into the wheel mill and mix well, dissolve 10g of dodecyl dimethyl hydroxypropyl sulfobetaine (HSB-12) in 500g of water and batch Add it into the wheel mill and mix evenly, then dilute 100g of silica sol with a mass concentration of 25% with 1400g of water, add it to the wheel mill in batches and mix for 40min, take it out and let it stand for 60min to get the mixture, then put the mixture in double Carry out extrusion molding in the screw extruder, obtain the cylindrical shaped body that diameter is 3.5mm; Described white carbon black is prepared by precipitation method;
[0044] Step 2. Dry the molded body obtained in step 1 at 130°C for 5 hours, then place it in a muffle furnace, and heat it up to 600°C for 10 minutes in an air atmosphere at a rate of 5°C / min to obtain a catalyst carrier.

Embodiment 3
[0048] The preparation method of the present embodiment catalyst carrier comprises the following steps:
[0049] Step 1. Add 970g of white carbon black and 30g of silicon carbide to the wheel mill and mix well. Dissolve 20g of Tween 80 in 500g of water and add them to the wheel mill in batches to mix evenly. After the water glass is diluted with 1390g of water, it is added to the wheel mill in batches and mixed for 10 minutes. After taking it out and standing for 60 minutes, the mixture is obtained, and then the mixture is placed in a twin-screw extruder for extrusion molding to obtain a cylinder with a diameter of 3.5mm. Forming a body; the white carbon black is prepared by a precipitation method;
[0050] Step 2. Dry the molded body obtained in step 1 at 200°C for 6 hours, then place it in a muffle furnace, and heat it up to 500°C for 300 minutes in an air atmosphere at a rate of 5°C / min to obtain a catalyst carrier.
[0051] The binder in this embodiment can also be water,...
