[0059] The adsorption tower of this embodiment adopts the adsorption tower and adsorbent filling technology of the present invention. The adsorption process requires four proprietary adsorbents, adsorbents a, b, c, and d. According to the specific implementation method, the four kinds of adsorbents are sequentially made into wire mesh roll columns according to the packing volume, and the packing volume ratio of the four kinds of adsorbents is 25:30:30:15. The operating conditions of the adsorption tower are shown in Table 2.
