The invention provides a method for preparing a mercury removing agent from a waste methanol catalyst. The method comprises the following steps: (1) crushing the waste methanol catalyst and mixing the crushed catalyst with a binder, extruding the mixture into strips, drying and calcining at 350-500 DEG C for 1-8 hours to obtain a mercury removing agent precursor; and (2) putting the mercury removing agent precursor into contact with sulfur-containing waste gas for sulfidizing treatment, and drying to obtain the mercury removing agent. According to the method for preparing the mercury removing agent from the waste methanol catalyst, as the waste methanol catalyst is taken as the raw material, resources can be saved, the cost can be reduced, and aluminum in the waste methanol catalyst also can be kept functioning in binding and enhancing adsorption in the final product mercury removing agent; the existing aluminum also serves as a carrier and has an excellent dispersion effect on the CuS active component; as a result, the mercury removal performance can be improved and the mercury removing agent is enabled to have relatively high mercury capacity.

The invention discloses a nicotine load slow-releasing agent and a preparation method and application thereof. The nicotine load slow-releasing agent is mainly prepared from effective components in percentage by weight: 0.488% of zirconium salt, 99.164% of acidamide and 0.347% of organic carboxylic acid. The zirconium salt, the acidamide and the organic carboxylic acid are utilized to form metal-organic frameworks (MOFs), thus the slow-releasing agent has a three-dimensional structure, has the large specific surface area, a large pore passage gap and an obvious pore structure, and has good compatibility with tobacco, aroma of the tobacco is not affected, and the nicotine load slow-releasing agent is non toxic and harmless, has no peculiar smell and has good thermal stability.
