Description
본 발명은 비석(沸石 Zeolite)이라고 한느 천연 광물을 이용하여 사소한 처리로서 수분 흡착제와 기타 기체 흡착제로서 시리카겔(Silicagel)을 능가하는 실용성 있는 염가의 제품을 생산함을 목적으로 발명한 비석 흡착제 제조방법에 관한 것이다.The present invention relates to a method for preparing a zeolite adsorbent for the purpose of producing a practically inexpensive product that exceeds the silica gel as a water adsorbent and other gas adsorbents by a minor treatment using a natural mineral called zeolite. It is about.
종래에는 약품이나 기구의 수분 흡착제 또는 건조제로서 현재까지는 시리카겔을 사용하고 있으나 시리카겔은 수분흡착량이 자체 중량에 비해 20%정도였어 실용면에 뒤떨어질 뿐만아니라 제품 자체가 규산 소다를 원료로하는 합성 물질이어서 생산비가 많이 든다.Conventionally, silica gel has been used as a moisture adsorbent or desiccant for medicines or appliances.Silica gel has a water adsorption amount of about 20% compared to its own weight. It is a material, so production costs are high.
그리고 강산을 사용하는 탓으로 폐수 문제등 복잡한 결솨를 초래하는 폐단이 있다.And because of the use of strong acids, there are some disadvantages that lead to complex consequences such as waste water problems.
천연 비석을 흡착제로 이용하는 특허가 미국, 카나다, 일본 등지에서 최근에 이루어지고 있으나 그들은 단일 처리법이며 본 발명인이 연구한 연속처리 과정과는 다를뿐만 아니라 본 발명인의 방법에 의한 국산 천연 비석의 성능이 월등하게 우수한 실적을 나타 내었다. (아래 도표 참조)Patents using natural zeolite as an adsorbent have recently been made in the United States, Canada, Japan, etc., but they are a single treatment method and differ from the continuous treatment process studied by the inventors, and the performance of the domestic natural zeolite by the inventors method is superior. Showed excellent performance. (See chart below)
*연속 처리법의 0.5N HCl-0.5N NaOH 용액 처리법이 본 발명인의 방법이다. * The 0.5N HCl-0.5N NaOH solution treatment of the continuous treatment is the method of the present inventors.
본 발명인은 이와 같은 종래의 문제점을 해결하여 한국의 공업 발전에 도움을 주고자 발명한 것으로 본 발명은 다음 실시예에 따라 상술하면 다음과 같다.The present inventors have invented to help Korea's industrial development by solving such a conventional problem, the present invention will be described in detail according to the following examples.
[실시예]EXAMPLE
1. 본 발명에서 사용되는 원료는 경북 영일군 또는 월성군에서 생상된 천연 비석중 양이온 교환능(C. E. C)이 높고 비교적 불순물이라고 할 수 있는 다른 점토 광물의 함량이 40%미만인 비석을 원료광으로 한다.1. The raw material used in the present invention is a raw stone containing a zeolite having a high cation exchange capacity (C.E.C) among natural zeolites produced in Yeongil-gun or Wolseong-gun, Gyeongsangbuk-do, and having a content less than 40% of other clay minerals.
2. 원료광의 예비처리 과정2. Pretreatment process of raw materials
원료광을 100-300매쉬로 붕쇄한 후 반응조로 옮겨지고 탄산 카리슘이나 함유 철분이 많은 경우 빙초산 소다 용액 또는 Na2S2O4및 수산용액(또는 구연산)으로 약 70℃에서 1시간 처리하여 이들을 용출하고 순도를 높인다.After disintegrating the raw ore with 100-300 mesh, it is transferred to the reaction tank and treated with glacial acetic acid soda solution or Na 2 S 2 O 4 and aquatic solution (or citric acid) at about 70 ° C for 1 hour if it contains a lot of calcium carbonate or iron content. Elute them and increase their purity.
3. 원료광의 처리 과정3. Treatment of raw materials
위 예비 처리가 끝난 원료를 0.3N 내지 1N의 염산 용액으로 100℃정도에서 2시간 가량 가열 및 교반하면서 처리한 다음 세럭하여 0.5N 내지 NaOH용액으로 역시 100℃정도에서 2시간 가량 가열 교반하면서 연속 처리한 후 세척하여 원심 분리후 적당히 건조시킨다.The above pretreated raw materials are treated with 0.3N to 1N hydrochloric acid solution at 100 ° C. for 2 hours while heating and stirring, followed by washing and continuous treatment with 0.5N to NaOH solution at 100 ° C. for 2 hours. After washing, centrifuge and dry appropriately.
4. 성형 및 활성 과정4. forming and active process
위 본 처리를 거쳐 나온 시료를 혼합기로 잘 치대며 입상으로 성형한 후 완전 건조하고 450℃에서 활성화 시킨다. 활성화가 끝난 시료는 습기에 접하지 않도록 포장하는 것이다.The sample from the above treatment is beaten well with a mixer, molded into granules, completely dried and activated at 450 ° C. The activated sample is packaged to avoid contact with moisture.
이상과 같은 본 발면의 처리과정을 이론적으로 뒷받침하는 근거로서 천연 비석은 직경이 3A-11A의 세공을 형성하는 광물이다.As a basis for theoretically supporting the process of the present invention, natural zeolite is a mineral that forms pores of 3A-11A in diameter.
그러나 이온 교환된 양이온의 종류와 무정형 광물로 메꾸어져 있어 세공의 보기에도 균일성이 없을 뿐만 아니라 세공의 발달이 표면상으로 효력을 나타내지 못하고 있어 흡착제 또는 분자체(Molecular Sleve)로서 역활을 제대로 못하고 있다.However, since they are filled with ion-exchanged cations and amorphous minerals, they do not have uniformity in the appearance of pores, and the development of the pores is not effective on the surface, and thus does not function properly as an adsorbent or molecular sieve. .
이것은 예비 처리와 산처리에 의하여 흡수성이 약한 양이온을 먼저 용출하고 무정형 미분말을 용출시켜 세공을 크세하는 동시에 광물의 양이온 교환늠(C. E. C)을 증가(대체로 60부근의 것을 100정도로 C. E. C)를 증가시킬수 있다)시키는데 이때 수산이나 구연산 또는 그염으로 씻어내는 이유는 Fe등 중금속과 착염을 형성하여 쉽게 수용해 하도록 하는 작용을 한다.This is due to pretreatment and acid treatment, which elutes the weakly absorbing cations first, elutes the amorphous fine powder to fine pores, and increases the cation exchange scale (CE C) of minerals (approximately 60 to 100 C C). At this time, the reason of washing with aquatic acid or citric acid or salt thereof is to make complex salts with heavy metals such as Fe to easily accept them.
+예 + Yes
이와 같이 하여 처리된 광의 세공은 직경이 5A-11A 정도로 확대 되어있어 여기에 가성소다 용액으로 처리하면 광물의 세공내의 이온은 Na+로 치환(置換)되어 흡수성을 증가 기미게 되고 산터리로 인하여 세공이 확대된 뒤에 일어나는 치환인고로 더욱 그 효과가 크게된다.The pores of the light treated in this way are enlarged to about 5A-11A in diameter, and when treated with caustic soda solution, the ions in the pores of the mineral are replaced with Na + to increase the absorbency and the pores due to the acid battery. This effect is further increased by the substitution occurring after this enlargement.
또한 수분의 흡착의 근본 이유는 흡착력이 큰 세공의 함정(trap)효과도 있지만 수화력(水和力)이 큰 Na+의 약이온 효과가 크며 광물중에서 양이온 교환능(C. E. C)이 가장 큰 비석이 작용이 크다고 하는 것은 당연한 이치이며 거기에 세공의 흡착 효과도 더해져 나타나게 된다.In addition, the basic reason for the adsorption of water is the trap effect of the pores with high adsorption power, but the weak ion effect of Na + with high hydration power, and the zeolite with the largest cation exchange capacity (CE C) among minerals. It is natural that this is large, and the adsorption effect of a pore is added to it, and it appears.
이렇게 하여 제조된 본 발명의 흡착제는 수분 흡착력에 있어 광에 따라 차이가 있으나 자체 중량에 대해서 25%내지 50%정도의 것이 실용적이며 원비석 광물이 함유하고 있는 40%미만의 점토 광물은 성형시 고형물의 경도를 증가 시키는 바인다로서 적절한 효과를 나타내어 산업 발전에 유익 유용하게 이용될 수 있는 발명이다.The adsorbent of the present invention prepared in this way is different depending on the light in the water adsorption capacity, but it is practically about 25% to 50% by weight based on its own weight, less than 40% clay minerals contained in the ore minerals are solids during molding It is an invention that can be usefully useful for industrial development by showing an appropriate effect as a binder to increase the hardness of.
