Embodiment 1
[0032] 1) Dry 10 g of thiourea resin D402 in vacuum at 60 °C for 6 hours to obtain dried thiourea resin D402;
[0033] 2) Under stirring at room temperature, 1 g copper chloride was dissolved in 19 g deionized water to obtain a copper chloride solution with a mass fraction of 5%, and then the copper chloride solution was impregnated into 5 g dry sulfur On the urea resin D402, seal and stand for 2 hours, then completely dry the sample at 80 °C to obtain the precursor;
[0034] 3) In the flow of N 2 Under gas, the temperature of 5 g precursor was raised to 350 °C at a heating rate of 5 °C / min in a tube furnace for 1 hour, then raised to 500 °C at a heating rate of 3 °C / min and maintained for 3 hours, and then dropped to At room temperature, the catalyst NSC-1, N 2 The gas volumetric space velocity is 180 h -1 .
Embodiment 2
[0036] 1) Dry 10 g of thiourea resin D402 in vacuum at 60 °C for 6 hours to obtain dried thiourea resin D402;
[0037] 2) Under stirring at room temperature, 6 g of copper chloride was dissolved in 14 g of deionized water to obtain a copper chloride solution with a mass fraction of 30%, and then the copper chloride solution was impregnated into 5 g of dry sulfur On urea resin D402, seal and let stand for 2 hours, then completely dry the sample at 120 °C to obtain the precursor;
[0038] 3) Under the flowing He gas, the obtained precursor was heated in a tube furnace at a heating rate of 10 °C / min to 400 °C for 1 hour, and then at a heating rate of 5 °C / min to 900 °C and maintained 3 hours, then down to room temperature, namely to obtain catalyst NSC-2, He gas volume space velocity is 250 h -1 .
