1.1 features and application J108£2q catalyst is suitable for synthesis ammonia unit or hydrogen plant, to remove co and co2 at low concentration and make them to be inert gas, methane and water. This catalyst has high crushing strength, large pore volume, high activity and easily to be unloading. It has been obviously performing much better than other similar catalyst. 1.2 primary physical and chemical property 1) chemical composition Nio18 1.0% Tio26-8% Auxiliaries 40.5% Auxiliaries 2% Al23The rest Physical waterAlmost Volumetric shrinkageAlmost 2) main physical property ItemIndex Shape Grey-black ball Size mm 4. 5.5 Surface area m2/ 1.3 operation conditions Demand in gas material s content: Demand in gas material cl- content:03ppm Inlet co+co2 7% Up live temperature: 210 Service temperature: 220¡«43 Operation pressure: 32.0mpa Operation space velocity: 10000h-1.
