Description
本發明係有關於一種觸媒，特別是有關於一種分解揮發性有機物之觸媒及方法。
空氣污染嚴重危害人體健康以及環境。為減少污染物危害，歐盟設定2020年之減量目標：例如SO2
、NOx、VOCs、氨、PM2.5分別應較2000年減少82%、60%、51%、27%、59%。徵收空污費是台灣的污染物減量策略之一。基於VOCs之危害性，環保署自2006年開徵VOCs空污費，且計畫在2010年開始提高費率，估計將自原本每公斤12元提高到25~30元。
根據2003年統計資料，台灣每年排放到大氣中的揮發性有機物質(Volatile Organic Compounds,VOCs)超過864,000公噸。研究指出，以焚化法處理低濃度大風量VOCs之難度、所消耗能源及衍生排放之CO2
均極高。因此，目前已有許多節能設計被開發出來，例如，半導體業者多數以疏水性沸石轉輪吸附濃縮VOCs，之後將小風量高濃度VOCs進行直接高溫焚化處理或蓄熱式焚化處理。然而，即使選擇蓄熱式焚化仍需使用燃料。根據TSIA統計資料，目前台灣前十大半導體業者的瓦斯使用量約26,530,000m3
/年，費用約3.9億元/年(以14.65元/m3
計算)，二氧化碳排放量達到55,700噸/年。在節能及暖化議題日益高張之際，業者對於低能源成本、低碳排放的廢氣處理技術的需求隨之日益迫切。
中華民國專利I255324揭露一種有機廢氣處理系統及方法，利用濃縮轉輪吸附以脫附出濃縮的有機廢氣，並透過電漿火炬直接高溫熱解並迅速氧化濃縮廢氣。此外，更利用電漿火炬所產生的熱能預熱欲進氣處理的濃縮廢氣的溫度並提供濃縮轉輪脫附再生的熱源。
中華民國專利M320434揭露一種高效能濃縮器搭配高級氧化技術處理有機廢氣的淨化裝置，其設置一高級氧化處理單元於廢氣濃縮器脫附處理部的下游端，以氧化處理廢氣濃縮器所濃縮的有機物質。
然而，無論利用電漿或高級氧化仍需使用能源，其降低運作成本的效果有限，無法真正解決問題。
觸媒焚化明確的節約能源特性顯示其為具潛力的VOCs處理技術。用於完全氧化VOCs的催化劑大致可分為兩類：鉑或鈀等貴重金屬及鉻、鈷、銅、鎳和錳等過渡金屬氧化物。許多專利和文獻指出低溫催化氧化VOCs極具潛力。
美國專利第4,304,761揭露甲醇廢氣通過銀催化劑的氧化方法。銀在相對較低的反應溫度使甲醇高比例轉化為二氧化碳。然而，鉑和鈀則產生大量的醛類副產物。
本發明之一實施例，提供一種分解揮發性有機物之觸媒，包括：一中孔洞材料；以及一銀金屬，擔載於該中孔洞材料。本發明觸媒更包括一過渡金屬氧化物，擔載於該中孔洞材料。
本發明之一實施例，提供一種分解揮發性有機物之方法，包括：提供一含揮發性有機物之氣體；以及使該含揮發性有機物之氣體與上述之觸媒接觸，使該含揮發性有機物之氣體分解而氧化為二氧化碳與水。
銀金屬表面易吸附氧而具有氧化特質，而過渡金屬氧化物亦具有吸附氧及進一步提供氧給銀而促進VOCs之完全氧化之能力。本發明乃基於此一特性，設計製作出一以銀金屬及過渡金屬氧化物擔載於中孔洞之觸媒材料，可將VOCs分解並氧化為二氧化碳及水的觸媒。值得注意的是，在此觸媒存在下的氧化反應可於低溫條件下進行，有效解決了傳統高溫焚化之耗能及衍生之二氧化碳排放的問題。
為讓本發明之上述目的、特徵及優點能更明顯易懂，下文特舉一較佳實施例，作詳細說明如下：
本發明之一實施例，提供一種分解揮發性有機物的觸媒，包括一中孔洞材料，以及一銀金屬，擔載於中孔洞材料。本發明觸媒更包括一過渡金屬氧化物，擔載於中孔洞材料。
上述中孔洞材料可為氧化矽、氧化鋁或矽鋁氧化物，例如SBA-15。中孔洞材料孔徑大體介於2~50nm，比表面積介於600~1,000m2
/g。銀金屬和過渡金屬氧化物奈米粒子被擔載在中孔洞材料的表面和孔道。上述過渡金屬氧化物可包括氧化鉻、氧化鈷、氧化鈰、氧化鎳、氧化鐵、氧化鎂、氧化錳或其組合。
銀金屬的平均粒徑大體介於2~50nm。銀金屬於觸媒中的重量百分比大體介於1~30wt%。過渡金屬氧化物的平均粒徑大體介於2~50nm。過渡金屬氧化物於觸媒中的重量百分比大體介於1~30wt%。
本發明觸媒可將上述中孔洞材料藉由含浸、離子交換或沈積-沈澱等方法將銀金屬擔載於中孔洞材料而形成，期間經過一溫度介於100~800℃歷時數小時的熱處理程序。
本發明觸媒可進一步擔載於一蜂巢狀載體，其載體材料可以是氧化鋁、氧化矽、矽鋁氧化物、金屬或金屬氧化物。
本發明之一實施例，提供一種分解揮發性有機物的方法，包括下列步驟。首先，提供一含揮發性有機物的氣體。之後，使含揮發性有機物的氣體與上述的觸媒接觸，使含揮發性有機物的氣體分解而氧化為二氧化碳與水。
上述含揮發性有機物的氣體可為引擎排放氣體、有機溶劑揮發氣體或受污染空氣，而氣體中的揮發性有機物可包括烷類、烯類、芳香族類、酮類、醚類、醇類、有機酸類、胺類或其混合物，例如常見於半導體及光電產業排氣的異丙醇(IPA)、丙酮(acetone)、丙二醇甲醚(Propylene glycol monomethyl ether,PGME)或丙二醇單甲基醚醋酸酯(Propylene glycol monomethyl ether acetate,PGMEA)等。
上述含揮發性有機物的氣體與觸媒接觸的溫度可低於300℃，例如100~300℃。另含揮發性有機物的氣體與觸媒粒子接觸的空間速度大體介於3,000~200,000hr-1
。此外，含揮發性有機物的氣體與上述擔載觸媒之蜂巢狀載體接觸的空間速度大體介於1,000~20,000hr-1
。
銀表面很容易吸附氧而形成氧化觸媒。根據此特性，本發明提供了一種催化劑，包括一中孔洞材料，擔載銀和過渡金屬氧化物，可將揮發性有機物完全氧化成二氧化碳和水。具體來說，在此觸媒作用下，VOCs氧化可在低溫下進行，能有效地降低能源消耗和二氧化碳排放量。
