【発明の詳細な説明】
本発明はアルミナ分に富む石炭灰を主成分とする沸石の
製造方法に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for producing zeolite whose main component is coal ash rich in alumina.
従来石炭灰は、埋立用、肥料、人工骨、セメント原料、
セメント混和剤として利用され、その他の工業用原料と
しては現在利用されていない。Conventionally, coal ash is used for landfill, fertilizer, artificial bone, cement raw material,
It is used as a cement admixture and is not currently used as a raw material for other industrial purposes.
本発明は石炭灰の用途を開発すべく、鋭意研究を重ねた
結果、Ｎａ、 Ｋ、 Ｃａ、 Ｓｒ、 Ｂａミノ属炭酸
塩を加え溶融することによって容易に沸石の合成に利用
することができることを見出し、本発明を完成するに至
った。As a result of intensive research to develop uses for coal ash, the present invention has revealed that it can be easily used for the synthesis of zeolite by adding and melting Na, K, Ca, Sr, and Ba amino carbonates. This discovery led to the completion of the present invention.
本発明に利用した石炭灰は、鴻基炭仄、赤平炭仄および
清水沢炭灰であり、その灰の分析値を表これらの石炭灰
にＮａ、 Ｋ、 Ｃａ、 Ｓｒ、 Ｂａミノ属炭酸塩（
Ｎａ２ＣＯ３、Ｋ２ＣＯ３、ＣａＣＯ３、ＢａＣＯ３，
５ｒＣＯ３）を加え、電気炉を用いて溶融を行ない、溶
融物を水中に入れることにより沸石を合成することがで
きる。The coal ashes used in the present invention are Hongki coal ash, Akabira coal ash, and Shimizusawa coal ash, and the analysis values of the ash are shown below.
Na2CO3, K2CO3, CaCO3, BaCO3,
Zeolite can be synthesized by adding 5rCO3), melting it using an electric furnace, and placing the melt in water.
溶融温度はＮａ２ＣＯ３が一番低く９００℃でも完全に
溶融させることができる。Na2CO3 has the lowest melting temperature and can be completely melted even at 900°C.
溶融温度は用いる金属炭酸塩により異なる。The melting temperature varies depending on the metal carbonate used.
沸石はＷｍＺｎ０２ｎ−８Ｈ２０の形であられされ、こ
こにＷｍＮａ、 Ｋ、 Ｃａ、 Ｂａ、 Ｓｒ、 Ｚ＝
Ｓｉ＋ＡＩ＋Ｆｅで・あり、Ｓｉ： （ＡＩ＋Ｆｅ）
＞１という条件があり、Ｓは一定しない。Zeolite is found in the form of WmZn02n-8H20, where WmNa, K, Ca, Ba, Sr, Z=
Si+AI+Fe, Si: (AI+Fe)
>1, and S is not constant.
例えばＮａを例にとればＮａ２Ｏ・Ａｌ２Ｏ３・ｍ５ｉ
Ｏ２・ｎＨ２Ｏ（ｍ−３〜４、ｎ〉６）であられすこと
ができ、ＡＩの位置にはＦｅが入りうる。For example, taking Na as an example, Na2O・Al2O3・m5i
O2·nH2O (m-3 to 4, n>6) can be used, and Fe can be placed in the AI position.
従って石炭灰の中の（Ａ１２０３ ＋Ｆｅ２０３）モル
含有量に見合ったＮａ２Ｏ量よりも多いＮａ２ＣＯ３を
石炭灰に加える必要がある。Therefore, it is necessary to add more Na2CO3 to the coal ash than the amount of Na2O commensurate with the molar content of (A1203 +Fe203) in the coal ash.
Ｃａの場合は沸石はＣａＯ−Ａｌ２Ｏ３・ｍ５ｉｏ□・
ｎＨ２Ｏ（ｍ−３〜４、ｎ〉６）であられされる。In the case of Ca, zeolite is CaO-Al2O3・m5io□・
Arranged with nH2O (m-3 to 4, n>6).
実用的なものはＮａおよびＫの場合であるが、Ｎａ２Ｃ
Ｏ３を用いる方法がもつとも経済的である。Practical cases are Na and K, but Na2C
The method using O3 is also economical.
沸石は通常ゼオライト水と呼ばれ脱水と再水利とが自由
に行なわれ可逆的に出入する結晶水を有することや、塩
基交換能を有することが特徴であるので、硬水の軟化や
酸性土壌の改良剤として用いることができる。Zeolite is usually called zeolite water, and is characterized by having crystal water that can be freely dehydrated and rewatered, reversibly flowing in and out, and having base exchange ability, so it is useful for softening hard water and improving acidic soil. It can be used as an agent.
本発明によれば石炭灰を１００％有効利用することがで
き、経済的で工業的利用方法として好適である。According to the present invention, coal ash can be used 100% effectively, and is suitable as an economical and industrial utilization method.
次に本発明を実施例によりさらに詳細に説明する。Next, the present invention will be explained in more detail with reference to Examples.
実施例 １
鴻基炭灰１ｇに無水炭酸ナトリウム６ｇを加え、白金ル
ツボ中で１０００℃に３０分溶融を行った後、溶融物を
水の中に入れ加熱した後、濾過を行い水に不溶分を乾燥

を得ることができる。Example 1 6 g of anhydrous sodium carbonate was added to 1 g of Hongji coal ash and melted at 1000°C for 30 minutes in a platinum crucible.The melt was then heated in water and filtered to remove insoluble matter in water. Zeolite powder can be obtained by drying it at 100°C for 30 minutes in a drying oven and then taking it out.
このものの塩基交換量を測定して０．９２ｍｅｑＣａ／
ｇの値を得ることができた。The base exchange amount of this material was measured and was 0.92 meqCa/
We were able to obtain the value of g.
その他の実施例を表２に示す。Other examples are shown in Table 2.
