The composite catalyst is the compound of nitrate and chloride, which can be compound of nitrate, chloride and carbonate.
Description
Technical field
The present invention relates to a kind of preparation method of active carbon for pressure swing adsorption, be particularly useful for preparing carbon absorbent.
Background technology
At pressure swing adsorption method gas separation field, the performance of its adsorbent-active carbon just is the key factor of decision process efficient.The preparation process of transformation absorption activated carbon comprises steps such as moulding, charing, activation.In order to improve the performance indications of transformation absorption activated carbon, each manufacturer's concrete steps have certain difference again, and effect also is not quite similar.At present, the CO of international most advanced level transformation absorption activated carbon
2Adsorbance can reach more than the 75mL/g (40 ℃ reach 40mL/g during 1atm) under 0 ℃, 1atm; Bulk specific weight is more than 600g/L; In intensity more than 96%.And the CO of homemade transformation absorption activated carbon
2Adsorbance is under 0 ℃, 1atm, generally about 55mL/g (40 ℃, during 1atm at 30mL/g); Bulk specific weight is about 520～560g/L; Intensity is about 96%.Clearly, domestic carbon is at key index CO
2There is a big difference with international most advanced level on the adsorbance.
Summary of the invention
Technical problem: the purpose of this invention is to provide simple, the CO of a kind of method
2The preparation method of adsorbance height, cost is low, index is reached advanced world standards active carbon for pressure swing adsorption.
Technical scheme: the preparation method of a kind of active carbon for pressure swing adsorption of the present invention, with coal is raw material, after it is crushed to 200 orders, adding coal tar mixes to be pinched, in make-up machine, push slivering then, and make active carbon for pressure swing adsorption through operations such as charing, pickling, activation, mix to add in the fine coal of pinching and influence the raw molecule structure, can improve distribution of micropore and surface functional group kind, help improving CO adding coal tar
2The composite catalyst of adsorbance; Composite catalyst can be nitrate and chloride mix, also can be nitrate, chloride and carbonate mixture; The composite catalyst addition accounts for 1%～10% of ature of coal amount.The shared ratio of nitrate is 20%～80% in the composite catalyst; The shared ratio of chloride is 10%～80% in the composite catalyst; The shared ratio of carbonate is 0%～40% in the composite catalyst.
