Abstract
Description
본 발명은 습식 흡수법을 이용하여 바이오 가스 중에 함유되어 있는 황화수를 제거하기 위한 촉매조성물에 관한 것이다.The present invention relates to a catalyst composition for removing sulfide water contained in biogas using a wet absorption method.
바이오 가스는 매립장에서 발생되는 매립가스, 하수처리장 소화조에서 발생되는 소화가스를 비롯하여 축산분뇨 등 유기성 폐기물의 분해과정에서 발생되는 혼합가스로 주성인 메탄가스는 연료로 사용하고 있다.Biogas is a mixed gas generated during the decomposition of organic waste such as livestock manure as well as digested gas from landfill gas generated from landfill and sewage treatment plant digestion tank.
그러나 상기의 가스 중에는 수백~수천 PPM 단위의 황화수소가 존재하므로 악취는 물론 배관 및 연소장치에 부식을 일어키고, 연소 시 아황산 가스를 발생함으로 이를 정제하는 설비가 필요하다.However, since the hydrogen sulfide in the unit of hundreds to thousands of PPM is present in the gas, it is necessary to install a facility to purify the odor as well as to cause corrosion of the piping and the combustion apparatus, and to generate sulfurous acid gas upon combustion.
본 발명은 탈황방법의 하나인 습식 흡수법을 활용하여 혐기성 소화조 내의 황화합물을 효율적으로 제거하기 위한 소화가스 습식탈황용 촉매조성물에 관한 것이다.The present invention relates to a catalyst composition for wet desulfurization of digested gas for efficiently removing sulfur compounds in an anaerobic digestion tank by using a wet absorption method, which is one of desulfurization methods.
일반적으로 혐기성 소화가스는 당분, 전분, 알코올, 제지 그리고 식료품 제조공장, 또는 활성오니 공정을 이용한 하수 및 폐수 슬러지 및 음식물 쓰레기의 혐기성 소화 슬러지 처리시 발생하며, 이는 메탄가스가 주성분인 혼합가스로서, 연료로 사용이 가능하다. 하지만, 가스 중에 수백-수천 PPM 단위로 존재하는 황하수소는 배관 및 연소장치 등에 부식을 일으키며, 연소될 경우 이산화황으로 전환되어 배출되므로 정제가 반드시 필요하다.In general, anaerobic digestion gas is produced during the anaerobic digestion sludge treatment of sewage and wastewater sludge and food wastes using sugar, starch, alcohol, paper and food production plants, or activated sludge processes. Can be used as fuel. However, hydrogen sulfide present in the gas in units of hundreds to thousands of PPM causes corrosion to pipes and combustion apparatuses, and when burned, it is converted to sulfur dioxide and discharged, so purification is necessary.
현재 혐기성 소화조내의 황 화합물을 제거하기 위한 탈황방법으로는 크게 건식 흡수법과 습식 흡수법으로 나누어진다.Currently, desulfurization methods for removing sulfur compounds in anaerobic digesters are classified into dry absorption method and wet absorption method.
먼저 건식 흡수법은 산화철(Fe2O3), 활성탄 등과 같은 고체 흡착제와 접촉해서 황화합물을 제거하는 방식으로서 저온 및 저 습도에서 흡착성이 뛰어나지만, 고농도의 물질을 처리할 경우 발열이 심하게 일어나고, 가스의 온도가 높은 경우 흡착성능이 현저히 감소하며, 습도가 높은 가스를 처리할 경우 수분에 의한 흡착 방해 또는 채널링(channeling)현상에 의해 흡수의 반응속도가 느려 체적 시간이 길어지기 때문에 장치가 대형화하는 단점이 있다.First, the dry absorption method is a method of removing sulfur compounds by contact with solid adsorbents such as iron oxide (Fe 2 O 3 ) and activated carbon, and has excellent adsorption at low temperature and low humidity. Adsorption performance is remarkably decreased when the temperature is high, and when the gas is treated with high humidity, the size of the device becomes large because the reaction time of absorption is slowed due to the absorption reaction slowed by moisture or channeling phenomenon. There is this.
한편, 습식 흡수법은 기체와 액체(흡수제)가 세정장치를 통해 향류 또는 병류로 접촉해서 황 화합물을 제거하는 기술로서 가성소다법과 액상산화법이 상용화 기술로서 존재한다. 가성소다법은 가장 오랜된 기술로서 운전이 용이하고 성능이 뛰어나 과거에는 가장 보편화된 기술 중 하나였으나, 사용 후 발생되는 폐가소성소 다의 처리비용이 고가이며 혐기성 소화조 내의 이산화탄소와의 반응 때문에 과량의 가성소다가 소모되어 운전비용이 과다하다는 단점이 있고, 과량의 강알칼리 폐가성소다 발생으로 비환경친화적 기술로 분류되어 선진국에서는 기술보급이 중지된 상태이다.On the other hand, in the wet absorption method, a gas and a liquid (absorbent) come into contact with each other in countercurrent or cocurrent flow through a washing apparatus to remove sulfur compounds, and a caustic soda method and a liquid oxidation method exist as commercialization technologies. Caustic soda method is the oldest technology, and it is one of the most common technologies in the past because it is easy to operate and has excellent performance.However, the disposal cost of waste plastic soda after use is expensive and the excess caustic is caused by the reaction with carbon dioxide in the anaerobic digester. There is a disadvantage of excessive operating costs due to the consumption of soda, and it is classified as a non-environmentally friendly technology due to the generation of excessive alkaline caustic soda.
따라서, 황화합물을 효과적으로 제거하고, 오염발생이 없으며, 공정페기물의 2차 처리가 필요없는 친환경적이고 경제적으로 상용 가능한 탈황촉매의 개발이 시급한 실정이다.Therefore, there is an urgent need to develop a desulfurization catalyst that can effectively remove sulfur compounds, eliminate pollution, and do not require secondary treatment of process waste, which is eco-friendly and economically viable.
국내특허 제347845호는 악취제거용 촉매조성물에 관한 발명으로 대기 중의 악취 유발 물질을 물에 흡수시킨 후 생성된 악취 유발 물질 함유 수용액을 산화 촉매의 존재하에 접촉 산화 반응시키는 것을 포함하는 대기 중의 악취 유발 물질을 특정의 촉매를 이용하여 접촉산화 반응에 의해 세정하고 있으나, 악취를 제거하기 위하여 먼저 악취유발물질을 물에 흡수시켜야 하고 물에 흡수된 악취를 제거하기 위하여 과산화수소, 오존, 공기 산소 등을 사용하야 하는 등 악취의 제거 공정이나 다양한 종류의 부촉매를 사용해야하는 등의 단점이 있다.Korean Patent No. 347845 relates to a catalyst composition for removing odors. The odor induced in the air includes absorbing the odor causing substances in the air into water and then performing a catalytic oxidation reaction of the resulting odor causing substance-containing aqueous solution in the presence of an oxidation catalyst. The material is cleaned by catalytic oxidation using a specific catalyst, but in order to remove the odor, the odor-causing substance must be absorbed into water first, and hydrogen peroxide, ozone, air oxygen, etc. are used to remove the odor absorbed by the water. There are disadvantages such as odor removal process or the use of various kinds of subcatalysts.
국내특허 제 598579호 발명은 마그네슘계를 촉매로 사용하여 재생성을 높일 수 있는 탈황 흡수제 및 제조방법에 관한 것이나 SO2를 흡수하는 MgO에 흡수력 증진성분으로 Ce 또는 Co 첨가물 및 재생성 증진 성분으로 Fe, Ti 를 첨가해야는 등의 번거로움이 있었다.Korean Patent No. 598579 relates to a desulfurization absorber and a manufacturing method which can increase regeneration by using magnesium as a catalyst, but Fe or Ti as an additive to increase Ce or Co and regeneration to MgO absorbing SO2. It was necessary to add such a hassle.
또한, 또한 미국특허 제4,369,130호는 열적으로 안정된 다공성 지지체를 사용하여 Bi, Cr 또는 Ce와 같은 희토류 금속과 두 번째 성분으로 K와 같은 알칼리금 속을 이용한 산화황 제거방법을, 미국특허 제4,735,705호는 spinel형태를 포함하는 알칼리 금속, Ca, Ba, Be, Sr의 혼합물을 FCC공정에 사용되는 FCC촉매에 첨가한 이산화황 제거방법을, 미국특허 제5,021,228호는 알루미나에 포함된 K, Th를 이용하여 산화황이 포함된 기체에 접촉시키는 산화황 제거방법을, 미국특허 제5,108,979호에서는 FCC환경에서 spinel을 사용한 산화황 감소방법을 각각 개시된바 있다.In addition, U.S. Patent No. 4,369,130 discloses a method for removing sulfur oxides using rare earth metals such as Bi, Cr or Ce and alkali metals such as K as a second component using a thermally stable porous support. Is a sulfur dioxide removal method by adding a mixture of alkali metal, Ca, Ba, Be, Sr containing a spinel form to the FCC catalyst used in the FCC process, US Patent No. 5,021,228, using K, Th contained in the alumina For example, US Patent No. 5,108,979 discloses a method for reducing sulfur oxides using spinel in an FCC environment.
그러나 효율적인 탈황제는 많은 양의 황을 제거할 수 있고 또한 재생이 잘 이루어지는 두 가지 요건을 우선적으로 갖추어야 하는데, 이러한 종래의 알루미나 마그네슘 화합물을 이용한 산화황 제거 방법은 탈황 성능이 낮고 특히 세륨이 첨가된 마그네슘 화합물의 경우는 재생이 용이하지 않은 단점이 있고, 황을 흡수한 MgO성분이 MgSO4로 전환 되는데 MgSO4가 매우 안정하여 흡수한 황의 탈착이 어려운 단점이 있었다.However, an efficient desulfurization agent must first satisfy two requirements that can remove a large amount of sulfur and are well regenerated. The conventional sulfur oxide removal method using the alumina magnesium compound has low desulfurization performance, especially magnesium added with cerium. If the compound has a disadvantage that is not susceptible to play, the MgO component has absorbed the sulfur is converted to the MgSO 4 was a disadvantage that the desorption of sulfur absorbed by the MgSO 4 is very reliable difficult.
본 발명은 상기와 같은 문제점을 해결하기 위하여 혐기성 소화가스의 황화합물을 특정의 촉매조성물에 의해 황화합물을 무해하고 무취한 황으로 전환시켜, 황화합물을 저감할 수 있도록 한 소화가스 탈황용 촉매조성물을 제조함을 목적으로 한다.The present invention to solve the above problems by converting the sulfur compound of anaerobic digestion gas into a harmless and odorless sulfur by a specific catalyst composition to prepare a catalyst composition for the digestion gas desulfurization to reduce the sulfur compound. For the purpose.

For the purpose of
