Abstract

To provide a catalyst for reforming an oxygen-containing hydrocarbon, the reforming activity and durability of which are improved by improving the performance of a copper-containing metal oxide having a spinel structure as the catalyst for reforming the oxygen-containing hydrocarbon and to provide a hydrogen or synthetic gas production method and a fuel cell system both using the catalyst. The catalyst for reforming the oxygen-containing hydrocarbon is prepared by the step of firing a mixture of the copper-containing metal oxide (A) having the spinel structure with a solid acid (B) at 300-850 DEG C in an atmosphere containing at least oxygen. The method for producing hydrogen or a synthetic gas comprises a step of subjecting the oxygen-containing hydrocarbon to any one of various reforming treatments using the catalyst. The fuel cell system comprises a reformer having the catalyst and a fuel cell utilizing hydrogen produced by the reformer as fuel.

Description

200911363 九、發明說明 【發明所屬之技術領域】 本發明係關於含氧碳氫化合物改質用觸媒、使用其製 造氫或合成氣體之方法及燃料電池系統。各詳細而言,本 發明係經由將含銅之具有尖晶石結構之金屬氧化物、與固 體酸的混合物,在含有氧的氣體環境下以特定的溫度燒成 處理的步驟而調製成的含氧碳氫化合物改質用觸媒;使用 此改質用觸媒對含氧碳氫化合物施以各種改質,有效率製 地造氫或合成氣體之方法;以及利用此改質用觸媒之燃料 電池系統。 【先前技術】 合成氣體,係由一氧化碳與氫所形成,使用於作爲甲 醇合成、羰基(0X0 )合成、費-托合成等之原料氣體以 外’廣泛地使用於作爲氨合成或各種化學製品的原料。 此合成氣體,可藉由先前技術之煤經氣化的方法、或 者以天然氣體等作爲原料之碳氫化合物類的水蒸氣改質法 或部份氧化改質法等而製造。惟,碳的氣化方法中,除了 需要複雜且高價的煤氣化爐,亦會有演變成大'規模的設備 等問題。此外,碳氫化合物類的水蒸氣改質法,因爲反應 伴隨著大量吸熱,故除了反應的進行需要700〜1200 °c左 右的高溫’需要特殊的改質爐之外,亦會有所使用的觸媒 被要求高耐熱性等問題。而且’碳氫化合物類的部份氧化 改質中’因爲需要高溫’故會有需要特殊的部份氧化爐, -5- 200911363 此外因爲隨著反應生成大量的煤,故除了此處理成爲問題 之外,亦會有觸媒易劣化等問題。 在此,爲了解決此問題,近年,嘗試使用二甲基醚( DME)等之含氧碳氫化合物作爲原料,對其施加各種的改 質,製造合成氣體。另一方面,近年,因爲環境問題而使 新能源技術受到注目,焦點集中在作爲此新能源技術之一 的燃料電池。 此燃料電池,係藉由使氫與氧進行電化學反應,使化 學能變換爲電能,具有能源的利用效率高的特徵,作爲民 生用、產業用或汽車用等之實用化硏究正積極地進行。此 外,發電效率高、最近注目度高的固體氧化物形燃料電池 ,除了氫以外亦可利用一氧化碳。作爲此燃料電池的氫源 (固體氧化物形燃料電池中,氫及一氧化碳源),甲醇、 甲烷爲主體之液化天然氣、此天然氣爲主成份之都市天然 瓦斯、以天然氣爲原料之合成液體燃料、而且石油系的石 油腦或燈油等之石油系碳氫化合物的硏究正在進行。 使用此等的石油系碳氫化合物製造氫時,一般而言相 對於該碳氫,觸媒的存在下施以水蒸氣改質處理或自熱改 質處理、部份氧化改質處理等,但此時產生如上述的問題 。所以’即使在氫的製造,使用二甲基醚等的含氧碳氫化 合物作爲原料之方法,進行各種嘗試,關於以二甲基醚等 之含氧碳氫化合物作爲原料,對其施以各種改質而製造氫 或合成氣體時所使用的觸媒,目前爲止亦揭示了各種觸媒 ,其中以使用Cu系的觸媒,作爲改質含氧碳氫化合物之 -6- 200911363 技術,揭示例如使用含Cu觸媒,由含氧碳氫化合物與二 氧化碳製造合成氣體之觸媒及使用其之合成氣體的製造方 法(專利文獻1等):使用含Cu觸媒,由含氧碳氫化合 物與水蒸氣製造氫之觸媒及使用其之氫的製造方法(專利 文獻2等):由固體酸上擔載含Cu之金屬者所成的含氧 碳氫化合物改質用觸媒(專利文獻3及4等):由含Cu 物質與固體酸性物質的混合物所成之含氧碳氫化合物與水 蒸氣製造氫之觸媒及使用其之氫的製造方法(專利文獻5 等);由.含Cu物質與固體酸性物質的混合物所成之含氧 碳氫化合物與水蒸氣製造合成氣體之觸媒及使用其之合成 氣體的製造方法(專利文獻6等)等。 惟,專利文獻1〜6技術中所使用的Cu系觸媒,皆活 性不足,所以,爲了提昇反應活性而提高反應溫度,則會 有無法避免觸媒劣化之問題。 爲了解決上述問題,提議含有含銅且具有尖晶石結構 之金屬氧化物,或進一步地含有固體酸性物質之含氧碳氫 化合物改質用觸媒(專利文獻7等),但活性尙未謂爲充 足。專利文獻7列舉作爲固體酸性物質之氧化鋁、二氧化 矽•氧化鋁、沸石等,而且記載著以氧化鋁爲佳。此外, 專利文獻8揭示Cu-Zn-Al型甲醇分解型觸媒與混合ZSM-5的觸媒,但與專利文獻7的觸媒比較下,會有易生成觸 媒劣化的原因之焦煤的問題。 另一方面,專利文獻9,以改質用觸媒II的例子的而 言,揭示將 CuMn擔載於氧化鋁後,經過假燒後以 200911363 5 0 0 ~ 1 0 0 0 °C的溫度進行燒成,但此技術在成爲尖晶石前擔 載於氧化鋁,然後藉由以高溫進行燒成而生成尖晶石,與 尖晶石結構者及氧化鋁混合後燒成之技術在本質上爲不同 者。 專利文獻1 :特開平10- 1 74869號公報 專利文獻2

[Prior Art] The synthesis gas is formed by carbon monoxide and hydrogen and is used as a raw material for ammonia synthesis or various chemical products, other than raw material gases such as methanol synthesis, carbonyl (0X0) synthesis, and Fischer-Tropsch synthesis. . This synthesis gas can be produced by a method of vaporizing coal of the prior art, a steam reforming method using a hydrocarbon such as a natural gas or the like, or a partial oxidation reforming method. However, in the gasification method of carbon, in addition to the complicated and expensive coal gasification furnace, there are problems such as the evolution of large-scale equipment.

To be sufficient. Patent Document 7 lists alumina, cerium oxide, alumina, zeolite, etc., which are solid acidic substances, and it is described that alumina is preferred. Further, Patent Document 8 discloses a catalyst of a Cu-Zn-Al type methanolysis type catalyst and a mixed ZSM-5, but in comparison with the catalyst of Patent Document 7, there is a problem of coking coal which is liable to cause deterioration of the catalyst. . On the other hand, in the example of the catalyst II for reforming, Patent Document 9 discloses that CuMn is supported on alumina, and after calcination, it is carried out at a temperature of 200911363 5 0 0 to 100 ° C.

Structure of compounds containing copper. Next, a case where a CuMn2〇4 spinel is prepared as an example of a method of preparing a metal oxide containing a spinel structure containing copper will be described. First, as a copper source, a water-soluble copper salt such as copper nitrate is used, and as a manganese source, a water-soluble manganese salt such as manganese nitrate is used, and the ratio of such a stoichiometric amount, that is, Cu and Μη, is prepared. The ear ratio is substantially an aqueous solution containing 1:2. Then, a chelating agent such as citric acid is added to the aqueous solution, and then heated to evaporate water to form a gel. Next, the gel is subjected to heat treatment to remove the oxide fine powder "obtained by nitrate or citric acid in the gel" by 300 to 5 Torr in the air.

When it is fired at a high temperature of 700 °C or higher, it is said to be a mixture of Μη203 and CiM.5Mm.5O4 spinel, but it can also be used as the component (A). In the method, a copper source can be used to make Cu exceed the stoichiometric ratio with respect to Μη. At this time, the obtained catalyst becomes copper oxide (Cu20 or CuO or a mixture thereof) and spinel type oxidation. A mixture of the materials may be used as the component (A). When a catalyst composed of CuFe204 spinel is prepared, an iron source such as a water-soluble iron salt such as iron nitrate may be used instead of the manganese source. Further, instead of the above-mentioned manganese source, a catalyst made of Cu(FeMn)204 spinel can be obtained by using a mixture of an iron source and a manganese source, and this material can of course be used as the component (A). The composition is formed into a pellet of a generally appropriate size and used in the present invention. The metal oxide having a spinel structure containing copper as the component (A) may be used singly or in combination of two or more kinds, but from the viewpoint of catalytic activity, particularly by 5 The Cu-Fe type spinel obtained by firing at a temperature of 0 0 to 1 0 0 ° C is suitable for 0 (solid acid).

However, from the viewpoint of the activity of the catalyst obtained in these, alumina is relatively Suitable as the alumina used for the solid acid, a commercially available crystal form of any of α, Z, r, c, 0, /c, and % can be used, and boiled boehmite can also be used. Alumina hydrate sintered by magnesium aluminophosphate, gibbsite, etc. In addition, an alkali buffer having a pH of about 8 to 10 is added to aluminum nitrate to form a hydroxide, which may be used for firing, or may be fired into aluminum chloride. The alkoxide is dissolved in an alcohol such as 2-propanol, and an inorganic acid such as hydrochloric acid as a catalyst for hydrolysis is added to prepare an alumina gel, and a sol/condensation which is dried and fired can be used. In the present invention, as the component (B), one type of the above solid acid may be used alone or two or more types may be used in combination, but from the viewpoint of catalyst activity, in particular, 300 to 75 The r-alumina obtained by firing at a temperature of about 〇 °c is suitable. (Baking treatment) The catalyst for reforming according to the present invention is a gas containing oxygen in a mixture of a metal oxide containing a copper-containing spinel structure of (A) and a solid acid of (B) component. It is prepared by the steps of the firing treatment in the environment. The mixing ratio of the above component (A) to the component (B) is not particularly limited. From the viewpoint of catalyst activity, in the mixture, it is generally desired that the copper is -15-200911363 is 1 to 50% by mass. It is preferably in the range of 2 to 3 % by mass. The preparation method of the above mixture is not particularly limited, but various physical mixing methods can be employed. Further, in the case of a gas atmosphere at the time of firing, the oxygen-containing gas may be used without particular limitation, but it is suitable for an air environment from the viewpoint of economy and the like. The firing temperature is 3 〇 〇 ~ 850 from the viewpoint of catalyst activity. Preferably, it is preferably from 350 to 800 ° C. More preferably from 700 to 800. (: Select within a range of less than 300 °C. The effect of catalyst activity or durability is insufficient. If it exceeds 850 °C, it causes aggregation or phase change of solid acid, and it becomes impossible to exhibit acidity. The firing time is affected by the firing temperature, and it cannot be smashed 'but usually 10 minutes to 5 hours' is preferably about 1 to 20 hours. Further, the catalyst for the modification of the present invention is shot. In the measurement of the X-ray diffraction into the CuK α line, it is preferable to hold the ray intensity at least at the three positions of 2 0 4.1, 3 3.2 °, and 4 9 · 6, and have diffraction at this position.

The inventors of the present invention presumed that a CuFeAl spinel was formed by firing a mixture of CuFe spinel and alumina at a high temperature. Stone, this may become the cause of high activity. At this time, it is speculated that the Fe in the spinel exchanges with A1 and is squeezed. Fe exists in the form of Fe2〇3, and new peaks appear at 20 = 24.1°, -16-200911363 33.2°, 49.6°.

(Reduction treatment) In the present invention, the catalyst for reforming obtained after the calcination treatment as described above is carried out. By reducing treatment, the activity can be further increased; the reduction treatment is carried out by a gas phase reduction method in which a hydrogen-containing gas stream is treated, and a reducing agent is used. The wet reduction method is generally carried out under a hydrogen-containing gas stream at a temperature of from 15 Torr to 500 ° C, preferably from 200 to 400. (The temperature is carried out for 30 minutes to 24 hours) is preferably When it is carried out for ~~ hours, in addition to hydrogen, inactive gases such as nitrogen, helium, and argon may be coexisted.

By. Further, by flowing the reaction raw material, the catalyst can be reduced by the generated hydrogen or CO in the reaction. In the present invention, the catalyst is detached from the spinel structure due to the pre-reduction treatment or the gas generated by the reduction, although the spinel structure becomes a partially or completely unretained state, The initial use of a Cu catalyst having a spinel structure is an important point of the present invention. The oxygen-containing hydrocarbon to be used in the catalyst for reforming of the present invention is preferably an alcohol such as methanol or ethanol, or an ether such as dimethyl ether or methyl ethyl ether. The base ether is particularly preferred.
