Description

306884 A7 86.1. 9 _B7 ：_ -- _ Z、發明説明（1 ) 發明領域 本發明涉及變壓吸附（PSA)領域，提供使用改良的氧 化鋁吸附劑從一氣體中去除二氧二碳的PSA的方法。 發明背景 在空氣導入到將氮氣和氧氣相互分離的低溫空氣分離 過程中之前，需要去除空氣中存在的低含量如400ppm的 二氧化碳。如果不進行該步驟，則二氧化碳會在空氣分離 裝置中固化。一般用於去除這種二氧化碳的兩種方法是變 溫吸附（TSA)及變壓吸附。 在這兩種技術中，吸附床暴露於原料空氣流中一段時 間以從空氣中吸附二氧化碳。此後，關閉原料空氣流使不 能進入吸附床，並通入沖洗氣流將吸附劑上所吸附的二氧 化碳帶走而將吸附劑再生以備繼續使用。在TSA中，通過 在再生相中加熱吸附劑而將二氧化碳從吸附劑脫附，在 PSA中，沖洗氣的壓力低於原料氣的壓力，壓力上的變化 被利用來從吸附劑中去除二氧化碳。 經濟部中央樣準局員工消費合作杜印製 (請先閱讀背面之注意事項再填寫本頁) 通過這些方法還可從原料空氣去除其它組分，包括烴 類和水。這些吸附方法也可應用於非空氣的原料氣體上或 應用到爲用於空氣分離設備以外的目的而純化的空氣上。 利用PSA在低溫空氣分離前從空氣中除去二氧化碳的 文獻有很多，例如美國專利4 2 4 9 9 1 5和美國專利 4477204。最初的方法是採用二張氧化鋁床去除水接著一 張沸石床如13X床去除二氧化碳。此後，已有建議使用全 -3 - 本紙張尺度適用中國國家標準（CNS > A4規格（2丨0>：297公釐） 306884 A7 B7
