Embodiment 1
[0035]This example uses the red brick powder manufactured by Huaan Industry and Trade Co., Ltd. in Xintai City, Shandong Province as the catalyst carrier, including the following steps: sieving the collected red brick powder, and taking the red brick powder with a particle size of 200 to 400 mesh as the catalyst Carrier, put the selected red brick powder into ultra-pure water and rinse continuously until the cleaning solution is free of turbidity, dry the red brick powder with impurities removed in a temperature environment of 110°C for 12 hours, and immerse 20g of the dried red brick powder in the containing 0.02 mol nickel nitrate solution for 12 hours, then the red brick powder soaked in the nickel nitrate solution was dried for 12 hours at a temperature of 110°C, and the dried red brick powder loaded with nickel nitrate was placed in a protective gas atmosphere at a temperature of 500°C Under heating for 10min. The catalyst prepared by the above method has a specific surfa...
