Example Embodiment
[0031] Example one
[0032] The catalyst used in the coal-to-natural gas methanation reactor of this embodiment mainly includes active components, a carrier, a first auxiliary agent, a second auxiliary agent and graphite, and the mass percentage content of each component is: NiO: 10% , Al 2 O 3 : 75%, CeO 2 : 5%, CuO: 8%, graphite 2%.
[0033] In this embodiment, a catalyst used in a coal-to-natural gas methanation reactor is prepared by a method including the following main steps:
[0034] Step 1: Weigh 19.46 grams of hydrated nickel nitrate Ni(NO 3 ) 2 ·6H 2 O, 7.96 grams of cerium ammonium nitrate (NH 4 ) 2 Ce(NO 3 ) 6 , 12.15 grams of hydrated copper nitrate Cu(NO 3 ) 2 ·3H 2 O, 275.94 grams of hydrated aluminum nitrate Al(NO 3 ) 3 ·9H 2 O and 78.73 grams of urea, and then add deionized water to dissolve and dilute the weighed substances to 2500ml to form a mixed solution. Calculated based on all metal ions in the precipitation solution, the precipitant excess is 5%;
