Embodiment 1
[0033] SiO 2 / Al 2 o 3 25 mordenite 195g with γ-Al 2 o 3 Mix 107.1g evenly, then add dilute nitric acid and safflower powder, knead evenly, extrude into strips, roast to make a carrier, cut into pellets and place in an impregnation container. The metal precursor iridium chloride was dissolved in water, mixed evenly, impregnated with the surface of the carrier, dried at 120°C for 4 hours, and calcined at 500°C for 3 hours to prepare the catalyst HC-5.
[0034] In a fixed-bed reactor, install 20 grams of catalyst HC-5, feed hydrogen, heat up to 400°C, purging for two hours for reduction activation, the reaction temperature is 400°C, the pressure is 3MPa, according to WHSV=2.5h -1 Working condition feed, hydrogen hydrocarbon molecular ratio 3.0. Raw material cyclohexane. The catalyst reaction performance results are shown in Table 1. The catalyst reaction remained stable for 300 hours.

The metal precursor nickel nitrate was dissolved in water, mixed evenly, impregnated with the surface of the carrier, dried at 120°C for 4 hours, and calcined at 500°C for 3 hours to prepare the catalyst HC-6.
[0037] In a fixed-bed reactor, install 20 grams of catalyst HC-6, feed hydrogen, heat up to 400°C, purging for two hours for reduction activation, the reaction temperature is 400°C, the pressure is 3MPa, according to WHSV=2.5h -1 Working condition feed, hydrogen hydrocarbon molecular ratio 3.0. Raw material cyclohexane. The catalyst reaction performance results are shown in Table 1. The catalyst reaction remained stable for 300 hours.
Embodiment 3
[0039] SiO 2 / Al 2 o 3 25 mordenite 195g with γ-Al 2 o 3 Mix 107.1g evenly, then add dilute nitric acid and safflower powder, knead evenly, extrude into strips, roast to make a carrier, cut into pellets and place in an impregnation container. The metal precursor nickel nitrate was dissolved in water, mixed evenly, impregnated with the surface of the carrier, dried at 120°C for 4 hours, and calcined at 500°C for 3 hours to prepare the catalyst HC-7.
[0040] In a fixed-bed reactor, install 20 grams of catalyst HC-7, feed hydrogen, heat up to 400°C, purging for two hours for reduction activation, the reaction temperature is 400°C, the pressure is 3MPa, according to WHSV=2.5h -1 Working condition feed, hydrogen hydrocarbon molecular ratio 3.0. Raw material cyclohexane. The catalyst reaction performance results are shown in Table 1. The catalyst reaction remained stable for 300 hours.
