[0001] The invention relates to the technical field of NMP honeycomb zeolite adsorption material production equipment, in particular to a preparation method of an NMP honeycomb zeolite adsorption material. Background Art

[0002] Honeycomb zeolite has the functions of adsorption and ion conversion. Since each zeolite has a specific uniform pore size (0.3-1nm), it can only pass molecules of corresponding size. Honeycomb zeolite is widely used as a catalyst, carrier, desiccant, feed additive, soil conditioner, sewage purifier, plastic and paper filler, seawater potassium extraction, etc., and has been widely used in cement production.

[0003] According to Chinese patent number CN107583604A, it belongs to the field of environmental protection technology of inorganic non-metallic adsorption materials, and specifically relates to a hydrophobic honeycomb zeolite material and its preparation method and application. The material includes ZSM-5 zeolite and Y-type zeolite, wherein ZSM-5 zeolite and Y-type zeolite account for 80-84% of the hydrophobic honeycomb zeolite material, and the transformed crystal accounts for 12-18% of the hydrophobic honeycomb zeolite material. The mass ratio between ZSM-5 zeolite and Y-type zeolite is 2:3-3:2, and the micropore diameter range of the hydrophobic honeycomb zeolite material is 0.5-2.0nm. The hydrophobic honeycomb zeolite material provided by the present invention selects the mixed treatment of ZSM-5 molecular sieve and Y-type molecular sieve material, so that the honeycomb zeolite material broadens the range of pore size (0.5-2.0nm), which meets the basic demand for adsorbing waste gas of different molecular sizes (i.e. 0.4nm-1.4nm) in large air volume and low concentration VOCs. Through the steps of crystallization, hydrophobicity, acid washing and other steps, the hydrophobicity and specific surface area of ​​the honeycomb zeolite material are improved, and the application of the hydrophobic honeycomb zeolite material to large air volume and low concentration VOCs in RH80% high humidity air environment is realized.
