Description
本發明係有關於一種燃料重組蜂巢觸媒反應裝置，尤指涉及一種可提升甲烷蒸氣重組反應器之轉化率，特別係指具有結構簡單、體積小、操作靈活、且設備及操作成本低，並可簡易地將此反應裝置以並聯方式加以擴充，具有便攜型產氫設備與較大規模經濟優勢等優點之燃料重組蜂巢觸媒反應裝置。 The invention relates to a fuel recombination honeycomb catalyst reaction device, in particular to a conversion rate of a methane vapor recombination reactor, in particular to a simple structure, small volume, flexible operation, low equipment and operation cost, and The reaction device can be easily expanded in parallel, and has a fuel-recombinant honeycomb catalyst reaction device with advantages of portable hydrogen production equipment and large-scale economic advantages.
在世界各國追求經濟成長之際，能源之需求與日遽增，然而可用之化石燃料存量卻日益減少，在可預見之未來，人類將面臨能源成本日益增加與能源短缺等問題。不僅如此，在全世界對環境品質所頒訂之法規要求愈趨嚴謹之下，其中如溫室氣體(主要為二氧化碳)之排放也受到世界各國重視，因此尋求高效能與新潔淨能源之迫切需求已逐漸顯現，其中固態氧化物燃料電池(Solid Oxide Fuel Cell,SOFC)係未來最有希望之潔淨能源之一，主要因為其具有高發電效率與低二氧化碳釋放率之優勢。 As countries around the world pursue economic growth, the demand for energy is increasing, but the available fossil fuel stocks are declining. In the foreseeable future, human beings will face increasing energy costs and energy shortages. Moreover, the regulatory requirements for environmental quality in the world are becoming more stringent, and the emission of greenhouse gases (mainly carbon dioxide) is also valued by countries around the world. Therefore, the urgent need to find high-efficiency and new clean energy has been It is gradually emerging that Solid Oxide Fuel Cell (SOFC) is one of the most promising clean energy sources in the future, mainly because of its high power generation efficiency and low carbon dioxide release rate.
重組產氫依含氫物料來源可分為有天然氣、石油、煤炭及電解水等方式，但目前其中仍以天然氣產氫佔大宗。由於天然氣蘊藏量豐富，約為目前已知全球化石燃料等能源之有機碳總儲量之兩倍，極可能成為二十一世紀最重要能源資源之一。因此目前各國無 不爭先研發天然氣產氫之能源，以求未來能在掌握能源中占有一席之地。天然氣主要成份為甲烷(CH4)，其含量約佔85~95%，甲烷係含氫比例最高之碳氫化合物，可產生氫氣之比例也最高。 Recombinant hydrogen production sources can be divided into natural gas, petroleum, coal, and electrolyzed water. However, hydrogen is still produced in large quantities. Due to the abundant natural gas reserves, it is about twice the total organic carbon reserves of energy sources such as global fossil fuels, and it is likely to become one of the most important energy resources in the 21st century. Therefore, at present, all countries are eager to develop energy sources for natural gas hydrogen production in order to gain a place in the future. The main component of natural gas is methane (CH 4 ), which accounts for about 85 to 95%. The hydrocarbon with the highest proportion of hydrogen in methane is the highest in hydrogen production.
然而，傳統蒸氣重組產氫製程複雜且占空間，必須簡化設備之複雜性及提高觸媒效能。而現有重組器在高溫下進行反應時，以鎳基顆粒觸媒填充，存在有床層壓降大、導熱性能差、顆粒觸媒受熱應力衝擊易破碎及積碳等問題，其中尤以積碳會形成觸媒表面活性中心被覆蓋與孔道阻塞，嚴重時還會使觸媒粉化，進而影響燃料電池之發電運轉。Rostrup-Nielsen及Hansen曾對不同金屬觸媒積碳速率進行研究(Rostrup-Nielsen,J.R.,Hansen,J.H.B.,J.Catal.144(1993)38)，在CH4/H2=95/5反應後，由熱重分析(Thermogravimetric Analysis,TGA)量測出積碳結果如第2圖所示，證實鎳金屬有嚴重之積碳現象。 However, the conventional steam recombination hydrogen production process is complicated and takes up space, and the complexity of the equipment and the catalyst efficiency must be simplified. However, when the existing recombiner is reacted at a high temperature, it is filled with a nickel-based particle catalyst, and there are problems such as a bed laminate reduction, a poor thermal conductivity, a particle catalyst subjected to thermal stress, a brittle fracture, and carbon deposition, among which carbon deposition is particularly common. The surface active center of the catalyst will be covered and blocked by the pores. In severe cases, the catalyst will be powdered, which will affect the power generation operation of the fuel cell. Rostrup-Nielsen and Hansen have studied the carbon deposition rates of different metal catalysts (Rostrup-Nielsen, JR, Hansen, JHB, J. Catal. 144 (1993) 38), after CH 4 /H 2 =95/5 reaction The results of carbon deposition measured by Thermogravimetric Analysis (TGA) are shown in Fig. 2, which confirms that nickel metal has a serious carbon deposit.
本發明之申請人-核能研究所在2003年開始SOFC系統之研發計畫，其中以天然氣產氫重組反應後之富氫氣體可提供為SOFC系統所需之燃料。而先前本所為SOFC系統研發之甲烷重組器採用γ-氧化鋁(γ-Al2O3)擔體之鎳基顆粒重組產氫觸媒，經重組產氫反應後會發生觸媒粉化與積碳現象，且後端產出之富氫氣體也會造成一流量不穩之脈衝壓降，甚至觸媒粉塵與積碳會藉由氣體管路污染到後面之SOFC系統，造成阻塞系統當機，誠如民國97年黃孟涵等人於文獻中之說明(重組觸媒的長效測試與探討，核能研究所技術手冊及技術程序書INER-OM-1218R，民國九十七年)，可見此觸媒重組器對其他設備造成之影響極大。故，一般習用者係無法符合使用者於實際使用時之所需。 The applicant of the present invention, the Nuclear Energy Research Institute, started the development of the SOFC system in 2003, in which the hydrogen-rich gas after the recombination reaction of natural gas hydrogen can be supplied as a fuel for the SOFC system. Previously, the methane recombiner developed by the Institute for SOFC system uses a nickel-based particle-recombinant hydrogen-producing catalyst of γ-alumina (γ-Al 2 O 3 ) support. Catalyst pulverization and accumulation occur after recombination of hydrogen production. Carbon phenomenon, and the hydrogen-rich gas produced at the back end will also cause a pulse pressure drop with unstable flow. Even the catalyst dust and carbon deposit will be polluted by the gas pipeline to the SOFC system behind, causing the blocking system to crash. As the Republic of China in 1997, Huang Menghan and others in the literature (long-term testing and discussion of recombination catalysts, nuclear energy research institute technical manual and technical procedures INER-OM-1218R, the Republic of China in 1997), can be seen in this catalyst The reorganizer has a huge impact on other devices. Therefore, the general practitioners cannot meet the needs of the user in actual use.
