〔産業上の利用分野〕
本発明は、エタノールを水素を主成分とするガスに改質
するエタノール改質用触媒に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an ethanol reforming catalyst for reforming ethanol into a gas containing hydrogen as a main component.
現在、では発電用ボイラ、内燃機関などに用いられる液
体燃料や気体燃料には、原油及びそれから精製された石
油類が使用されているが、最近の原油価格の高騰のため
燃料の多様化が指向されて、天然のバイオマス資源の発
酵反応によυ、また原油以外の化石燃料から合成され得
るエタノールが注目されている。Currently, crude oil and petroleum products refined from it are used as liquid fuels and gaseous fuels used in power generation boilers, internal combustion engines, etc., but due to the recent rise in crude oil prices, there is a trend toward diversification of fuels. As a result, ethanol, which can be synthesized through fermentation reactions of natural biomass resources or from fossil fuels other than crude oil, is attracting attention.
またエタノールはナフサよシはるかに低温で水素を主成
分とするガスに改質されるので、反応熱のための熱源と
して廃熱の適用が可能であると云う優位性をもっている
。Furthermore, since ethanol is reformed into a gas mainly composed of hydrogen at a much lower temperature than naphtha, it has the advantage that waste heat can be used as a heat source for reaction heat.
この際、生成した改質ガスは、改質反応の吸熱量相当分
（約１５ ＫｃａＡ／ｍｏｂ ）だけ改質ガスの発熱量
が増加するという利点と、さらに、この生成した改質ガ
スは高オクタン価で高出力設計の内燃機関に適用すると
圧縮比をあげて熱効率を改良することや、エタノール燃
焼時アルデヒド類などの排出もなくクリーン燃焼が可能
などの利点がある。At this time, the generated reformed gas has the advantage that the calorific value of the reformed gas increases by an amount equivalent to the endothermic amount of the reforming reaction (approximately 15 KcaA/mob), and furthermore, the generated reformed gas has a high octane value. When applied to internal combustion engines designed for high output, it has the advantages of increasing the compression ratio and improving thermal efficiency, and enabling clean combustion with no emissions of aldehydes when ethanol is burned.
内燃機関の排気ガス熱を利用してエタノールの改質反応
を行わす場合、排ガス温度は周知のごとく室温から８０
０℃程度の温度まで変化するため、幅広い温度範囲にわ
たって内燃機関に搭載できる程度の少量ですみ、かつ、
例えば、上記の８００℃程度の高温下におかれていても
、改質性能が劣化しない安定した触媒が要望されている
。When carrying out the reforming reaction of ethanol using exhaust gas heat from an internal combustion engine, the exhaust gas temperature ranges from room temperature to 80°C.
Since the temperature changes down to around 0℃, only a small amount is required to be installed in an internal combustion engine over a wide temperature range, and
For example, there is a demand for a stable catalyst that does not deteriorate its reforming performance even when placed at high temperatures of about 800°C.
従来、エタノールを改質する触媒としては、アルミナ（
以下Ａ４０３と記す）などの担体に、白金などの白金属
元素、又は銅、ニッケル、クロム、亜鉛などの卑金属元
素及びその酸化物などを担持した触媒が提案されている
が、これらの触媒は低温活性に乏しく、また耐熱性がな
いなど、現在までのところ多くの問題点を残している。Conventionally, alumina (
Catalysts have been proposed in which platinum metal elements such as platinum, or base metal elements such as copper, nickel, chromium, and zinc and their oxides are supported on a carrier such as A403 (hereinafter referred to as A403). To date, many problems remain, such as poor activity and lack of heat resistance.
例えばｒ−Ａ４０ｇに白金を担持した触媒については、
下記に示す目的の反応■が選択良く起こラス、エチレン
、エーテル、アルデヒド等の生成する副反応■が起こシ
やずいという問題がある。For example, for a catalyst in which platinum is supported on 40 g of r-A,
There is a problem in that although the desired reaction (2) shown below occurs selectively, side reactions (2), which produce ethylene, ether, aldehyde, etc., occur.
上記反応のうち、反応■は本発明でいうエタノール改質
反応の主反応でアシ、この反応で生成した改質ガスは、
改質反応の吸熱量相当分だけ改質ガスの発熱量が増加す
るという利点があシ熱効率改善につながる。Among the above reactions, reaction (1) is the main reaction of the ethanol reforming reaction in the present invention, and the reformed gas produced in this reaction is
This has the advantage that the calorific value of the reformed gas increases by an amount equivalent to the endothermic amount of the reforming reaction, which leads to improved thermal efficiency.
しかし、副反応■のような反応が起きると、この反応は
いずれも発熱反応であるため熱効率の面からはむしろ損
失となる。さらＫこの改質ガスを各種プロセスの水素源
などに利用する場合副反応■によって副生ずるエーテル
、アルデヒド類などは分離精製を困難にする要因となる
。However, if a reaction such as side reaction (2) occurs, this reaction is an exothermic reaction, and therefore results in a loss in terms of thermal efficiency. Furthermore, when this reformed gas is used as a hydrogen source in various processes, ethers, aldehydes, etc. produced as by-products due to side reaction (2) become a factor that makes separation and purification difficult.
また副反応■のうち、カーボン生成反応は、触媒の劣化
あるいは、リアクタの閉塞などをきたし、長期安定操業
の妨げとなる。Among the side reactions (2), the carbon production reaction causes deterioration of the catalyst or blockage of the reactor, which impedes long-term stable operation.

ていることを見いだし、本発明を完成するに至った。As a result of repeated research to solve the above problems, the present inventors have found that by interposing a third substance between alumina and the active metal, that is, by supporting a rare earth element oxide on alumina in advance, γ-A, which usually acts as an acidic catalyst
/40. Focusing on the fact that side reactions such as dehydration reactions can be suppressed by converting alumina to basicity, we have conducted various experiments and have developed rare earth element oxides that have the effect of suppressing side reactions in advance. The present inventors have discovered that a catalyst in which noble metals such as platinum and/or palladium are supported on a carrier coated with is extremely superior in both activity and selectivity in the ethanol reforming reaction, leading to the completion of the present invention.
