Examples
example 1
[0016] Weigh 49.72 grams of silicon dioxide as a carrier, prepare an aqueous solution containing 0.51 grams of rhodium chloride and 0.0514 grams of ruthenium trichloride, and use the prepared aqueous solution of silicon dioxide to stand, and then dry at 120°C. Then, it was reduced under hydrogen flow at 300°C to obtain a catalyst. Example 2
example 2
[0017] Weigh 48.75 grams of aluminum oxide support, prepare an aqueous solution containing 2.032 grams of rhodium chloride and 1.24 grams of nickel nitrate hexahydrate, impregnate the support with the prepared solution, place it, then dry it at 120°C and roast at 300°C. Then the catalyst was prepared by reduction at 400°C under hydrogen flow. Example 3
example 3
[0018] Weigh 48.5 grams of silicon dioxide as a carrier, configure an aqueous solution containing 2.032 grams of rhodium trichloride and 1.34 grams of chloroiridic acid, impregnate the silicon dioxide with the configured aqueous solution, let it stand, and then dry it at 120°C and roast at 400°C. Then, the catalyst was prepared by reduction at 300°C under hydrogen flow. Example 4
