Embodiment Construction
[0023] The present invention will be further described in detail below in combination with specific embodiments.
[0024] material selection
[0025] The active component of the catalyst is ferrous sulfate, or ferrous sulfate and manganese acetate.
[0026] The solvent can be water or deionized water, or other suitable solvents. In view of cost, it is preferable to use water as the solvent.
[0027] The catalyst carrier adopts anatase nano-titanium dioxide and molecular sieve. Molecular sieves may include A-type zeolite molecular sieves, X-type zeolite molecular sieves, Y-type zeolite molecular sieves, ZSM series molecular sieves, MFI molecular sieves, MOR molecular sieves, and the like.
[0028] Auxiliaries may include binders, extrusion aids and / or reinforcing agents, among others.
[0029] As the binder, clay is preferably used.
[0030] The extrusion aid preferably includes glycerin, and more preferably, the extrusion aid also includes Tianqing powder. In other embo...
