2results about How to "High desulfurization activity" patented technology

The application belongs to the technical field of adsorptive desulfurizer, and particularly relates to a high-strength nanometer zinc oxide composite desulfurizer and a preparation method thereof. The composite desulfurizer contains the following raw materials in parts by weight: nanometer zinc oxide / activated carbon composite material 65-70 parts, filler 15-25 parts, and binder 40-50 parts. The desulfurizer prepared by the application has high mechanical strength, high sulfur capacity and high desulfurization efficiency.

This invention provides a desulfurization adsorbent, its preparation method, and its application. The preparation method includes: dissolving a complexing agent in water and adjusting its pH value to obtain a treatment solution; wherein the complexing agent includes one or more combinations of polyethylene glycol, hexadecyltrimethylammonium bromide, and ethylenediaminetetraacetic acid; dispersing activated alumina in the treatment solution and heating under reflux to obtain modified alumina; dispersing the modified alumina in a solution containing an alkaline substance, then mixing it with a solution containing an active metal, hydrothermally crystallizing, and calcining to obtain the desulfurization adsorbent. The medium- and low-temperature flue gas solid desulfurization adsorbent provided by this invention has metal ions bonded to aluminum species in activated alumina and uniformly distributed on the surface of activated alumina, exhibiting high stability and sulfur capacity.
