201016303 六、發明說明: 【發明所屬之技術領域】 本發明係有關含有金屬水銀之廢氣的淨化方法,特別 有關使含於媒碳廢氣中之元素狀水銀(Hg)(以下稱金屬 水銀)於100〜200°C之低溫下進行氧化之廢氣的淨化方法 ’廢氣中之金屬水銀的氧化觸媒及其製造方法。 〇 【先前技術】 近年來,美國、歐洲對於防止由發電所、各種工場、 汽車等所排出之排煙中所含之氮氧化物(NOx)、硫氧化 物(Sox )等之外,更防止經由水銀(Hg)、鉛(Pb )、 鐵(F)等之各種微量成份之排出而危害健康的關切曰漸 提昇,進行限制此等排出量降至極低。特別是,由媒碳焚 化爐所排出之水銀其大部份以蒸氣壓高的金屬水銀形態於 大氣中釋放後,變成有機水銀之形態,以魚介類爲中心, ❹ 置入人類內體,而影響人類的健康。又,水銀對於成長期 之幼兒的神經具有重大危害,因此亦有報告指出水銀影響 美國幼兒20%導致神經異常之虞。由於該水銀對人類造成 重大的影響,故各方面意圖進行降低其之排出量。 代表降低廢氣中金屬水銀之方法者有使用脫硝觸媒或 其改良品’使廢氣中之NOx與氨(NH3 )還原,同時使揮 發性高之金屬水銀氧化成氯化水銀等之氧化形態之水銀後 ,於後流部之電氣集塵器、脫硫裝置下進行使氧化形態之 水銀化合物與燃燒灰、石膏共同去除之方法。作爲此時的 -5- 201016303 觸媒者,使用以作爲活性成份之釩、鎢等之氧化物爲活性 成份添加於氧化鈦者(專利文獻1 )。 此等觸媒一般於脫硝裝置與脫硝反應相同之350〜400 °C下被使用者爲常例,而既設鍋爐等設置間隙受約制時, 往電氣集塵器(EP)之出口的脫硝裝置設置被討論。又, 使金屬水銀氧化成其氧化形態之HgCl2之反應平衡愈低溫 則愈佔優勢,故使反應溫度作成愈低溫,則將更易取得高 度氧化率。惟,大量含二氧化硫(so2)之媒碳燃燒廢氣 之低溫處理時,其觸媒成份被硫酸氯化,so2被氧化之三 氧化硫(S03 )成硫酸,蓄積於觸媒細孔,導致觸媒劇烈 劣化之問題出現。爲防止此現象產生,因而設置觸媒於脫 硫裝置的後流中,或設法進行加熱後再生等(非專利文獻 1 ) ° 專利文獻1 :特開2003-53142號公報 非專利文獻 1 : G. Blysthe,B. Freeman, Bb. Lani, C., Miller, Mercury Oxidation Catalysts for Enhanced Control by Wet FGD, 2 0 0 7 Air Quality Conference, September 2 4-27, 2007 【發明內容】 如上述使用先行技術之觸媒,使Hg氧化於電氣集塵 器(EP )出口 150°C附近之溫度下進行使用後,於S02之 氧化生成物使活性成份進行硫酸氯化,或生成之硫酸使觸 媒細孔阻塞,導致觸媒急劇劣化。此等問題其後者之劣化 -6 - 201016303 係物理現象之惡化,因此只要觸媒成份稍加留意,即可回 避問題,又,低溫下之so2氧化動作並未明朗,因此防止 該觸媒劣化之策略並未充分掌控。 本發明之課題係鑑於上述先行技術之現狀,使so2於 S〇3進行氧化之過程明確,更進行解開活性成份之硫酸氯 化與硫酸成份之蓄積如何劣化之過程,基於此等發明,而 提供一種即使在含有so2之廢氣中,仍長期具有高活性之 Φ 金屬水銀去除用觸媒及使用其之金屬水銀之氧化方法。 爲達成該課題,本發明者針對含有S〇2之廢氣於低溫 下處理時之S〇2之氧化動作與氧化生成物(S〇3、S04離 子、硫酸等)之動作進行詳細硏討結果,得到以下發現, 基於此等進而完成本發明。 (1 )低溫中S〇2之氧化並非經由下述之氧進行氧化 反應(1式),而是與(2式)之NO進行反應爲中心。 (1式)之氧化反應於300 °c以上較佔優勢。 φ S〇2 + 1 / 2〇2 — S〇3 (1 式) 2NO+ S〇2 — N2〇+ S03 ( 2 式) (2)氧化鈦爲(2式)反應之理想觸媒。 (3 )經由S 02之觸媒的劣化係伴隨觸媒活性成份之 硫酸氯化之體積增加、與(2式)反應所生成之3 03作成 硫酸或酸性硫酸鹽類使觸媒之細孔阻塞所造成。於脫硝裝 置、EP所注入之氨殘留時,作成酸性硫酸銨將細孔阻塞 ,使劣化加速。 本發明係基於上述發現所完成者,本申請之專利申請 201016303 發明如下。 (1)使含有硫氧化物及金屬水銀之廢氣、與作爲第1 成份之氧化鈦、作爲第2成份之鎳(Ni)、錳(Μη)、或 釩之硫酸鹽、或磷酸鹽之觸媒’於100°C以上、2〇〇°C以下 進行接觸,使該金屬水銀進行氧化者爲其特徵之廢氣的淨 化方法。 (2 )含有以氧化鈦爲第1成份,以鎳(Ni )、錳( Μη),或釩之硫酸鹽,或磷酸鹽爲第2成份之廢氣中的金 參 屬水銀之氧化觸媒。 (3) 更含有鉬(Mo)或鎢(W)之含氧酸或含氧酸 鹽爲第3成份者爲其特徵之(2)所載之觸媒。 (4) 該觸媒之最大履歷溫度爲300°C以下之(2)或 (3)所載之觸媒。 (5) 使氧化鈦爲第1成份、鎳(Ni)、錳(Μη)、 或釩之硫酸鹽、或磷酸鹽爲第2成份,相對於第1成份, 第2成份的原子比爲0.03〜0.3,於水的存在下進行混煉 參 後,於基材進行塗佈、成形爲板狀,或蜂巢狀後,最大履 歷溫度爲300°C下進行乾燥、燒成者爲其特徵之金屬水銀 之氧化觸媒的製造方法。 (6) 於混煉該第1成份及第2成份時,進一步添加 鉬(Mo)或鎢(W)之含氧酸或含氧酸鹽爲第3成份者爲 其特徵之(5)所載之觸媒的製造方法。 (a)本發明中,藉由使用作爲觸媒活性成份之未進 行硫酸氯化之硫酸鹽或磷酸鹽,可防止伴隨觸媒硫酸氯化 -8- 201016303 之體積增加後的細孔阻塞。 (b)本發明之觸媒製造方法中’又使最高熱履歷溫 度限制於300 °C以下,可防止硫酸鹽或磷酸鹽與觸媒之氧 化鈦進行反應分解,可於使用階段減少體積的增加現象。 (C)進一步使S〇2之氧化(2式)避免經由氧化鈦而 促進氧化,除活性成份之硫酸鹽/磷酸鹽’更添加含有易 吸附於氧化鈦之Mo、W之含氧酸離子之化合物,被覆氧 ❹ 化鈦,抑制(2式)之氧化。經由以上,可大幅減少源於 低溫導致so2之金屬水銀的氧化觸媒劣化現象,得到長期 保持高度活性之觸媒。 藉由本發明,可淨化使用經由S03蓄積極少劣化之金 屬水銀之氧化觸媒的廢氣,於電氣集塵器出口等之H gCl2 生成之有利條件下可進行水銀處理。又,將先行技術之具 有Hg氧化機能的脫硝觸媒設置於廢氣預熱器與空氣預熱 器之間之無空隙之既設鍋爐時,如設置觸媒於電氣集塵器 Ο 之出口部,可輕易進行Hg之氧化。又,使用先行技術之 觸媒時,無需使所需之SO3劣化之觸媒進行昇溫再生,可 大大期待理想經濟面之效果。 【實施方式】 〔發明實施之最佳形態〕 用於本發明方法之觸媒重點在於使用作爲第1成份之 氧化鈦、作爲第2成份之鎳(Ni )、錳(Mn )、釩之硫酸 鹽或磷酸鹽’除此之外’又爲不使硫酸鹽、鱗酸鹽於觸媒 201016303 製造階段被分解,限制觸媒之最高履歷溫度於300 °C以下 爲極重要者。 其中所使用之氧化鈦可使用比表面積爲50〜3 00m2/ g者,而爲提昇低溫活性,使用高比表面積者較易得到理 想之結果。另外,硫酸鹽與磷酸鹽,只要是該鹽類,任何 鹽類均可使用,惟較佳者以對水之溶解度高,於觸媒調製 階段下溶解,被覆氧化鈦表面,較可得到抑制(2式)反 應之理想結果。又,未必一定要鹽類,亦可使用觸媒調製 @ 階段下經由複分解,形成硫酸鹽或磷酸鹽之第2成份化合 物之組合,如:硝酸鹽與硫酸、乙酸鹽與磷酸等之組合。 此時,爲使熱處理溫度維持於300°C以下,若選擇於其以 下之溫度進行蒸散之硝酸鹽、有機酸鹽,則較易得到理想 結果。 該第1成份與第2成份係指,於水的存在下進行混煉 ,必要時,添加矽熔膠、氧化鈦熔膠等之膠質狀結合劑, 或無機纖維類之補強材料,進行混煉後,塗佈於金屬、陶 ❹ 瓷基材,成形成板狀,或使用塑模成形成蜂巢狀後,進行 乾燥及燒成。燒成溫度爲防止鹽類分解與避免氧化鈦之燒 結,故爲300°C以下爲宜,通常於150〜200°C下燒成數小 時則可得到理想結果。其中對於所使用之第1成份之第2 成份之原子比亦依其氧化鈦之比表面積而異,一般選擇 0.03〜0.3者宜。若添加量太少時,不僅降低活性,使鹽 類被覆T i Ο 2表面抑制(2式)反應之效果變小容易劣化, 反之,添加量太多則因濕份導致膨潤之原因。因此,較佳 -10- 201016303 者選擇0.05〜0.2可輕易得到好結果。 又,該觸媒之調製階段,使用W或Mo之含氧酸、或 其銨鹽爲第3成份後,氧化鈦吸附該含氧酸離子,防止促 使S03生成反應之氧化鈦表面的露出,故具有有效防止往 S03、硫酸細孔內之蓄積之效果。該最適添加量雖不一定 亦受氧化鈦之比表面積之影響,而對於氧化鈦而言,以原 子比計爲〇.〇3〜0.3之範圍者宜,較佳者爲0.05〜0.2。該 φ 添加量小時,效果減少,太多將牽連觸媒製造成本的增加 〔實施例〕 圖1係代表本發明廢氣淨化方法之流程說明圖。由鍋 爐所排出之廢氣係通過脫硝裝置2、空氣預熱器3、電氣 集塵器4、及脫硫裝置6,進行處理,由煙囪7被排出系 外,而本發明觸媒係設置於電氣集塵器4之出口,廢氣中 參 之金屬水銀被氧化處理。圖2係代表於圖1之電氣集麈器 4與脫硫裝置6之間,設置收納本發明觸媒5之觸媒反應 器8之說明圖。使用本觸媒進行廢氣淨化時,如圖1所示 於電氣集塵器4之出口部份設置觸媒設置間隙,或如圖2 所示於電氣集塵器4與脫硫裝置6之間設置觸媒反應器8 ,於200〜100 °C之溫度下,使廢氣與觸媒進行接觸。其結 果,金屬水銀被氧化之同時,與廢氣中之HC1反應,形成 HgCl2,於後流之脫硫裝置6被去除。 以下,使用具體例,進行詳細說明本發明。 -11 -
