Abstract:
스프링형 전극을 포함하는 글라이딩 아크 방전 반응부, 상기 글라이딩 아크 방전 반응부의 출구에 형성된 촉매 반응부 및 전원공급부를 포함하는 휘발성 유기화합물의 처리장치 및 처리방법이 개시된다. 상기 휘발성 유기화합물의 처리장치 및 처리방법은, 금속 산화물 촉매를 도입함으로써 유해물질의 분해효율이 우수하고 반응 부산물이 적다. 또한, 아크 방전 반응기 출구에 촉매층을 결합함으로써 플라즈마가 촉매에 영향을 미치지 않으면서, 추가의 열원 없이 촉매를 활성화 시킬 수 있다는 장점이 있다. 글라이딩 아크 방전, 플라즈마, 휘발성 유기화합물, 촉매층, 금속 산화물
Abstract:
PURPOSE: A silica aerogel supported catalyst, and a methane conversion method using thereof are provided to induce the methane activation at the low temperature, and to secure the excellent yield of C2 hydrocarbon. CONSTITUTION: A silica aerogel supported catalyst contains a silica aerogel carrier, and sodium tungstate and a manganese oxide supported inside the silica aerogel carrier.

PURPOSE: A method for manufacturing a vacuum insulation panel using monolithic porous material and vacuum packing material and the vacuum insulation panel manufactured using the same are provided to economically manufacture the vacuum insulation panel by applying a vacuum packing technology using the vacuum packing material. CONSTITUTION: A method for manufacturing a vacuum insulation panel comprises the following steps: covering the outside of monolithic porous material using the vacuum packing material; evacuating the vacuum packing material; and sealing the vacuum packing material after the evacuation. The monolithic porous material is transparent aerogel. The vacuum packing material is composed of a polymer film having heat-adhesiveness, a tensile strength, cold resistance, or heat resistance.
Abstract:
PURPOSE: An ozone treatment system for dyeing wastewater and a continuous dye containing wastewater treatment process using the same are provided to reduce color as well as COD. CONSTITUTION: The ozone treatment system comprises three vertical reactors consisting of three packed towers(1,2,3); three recycling tanks(1-a,2-a,3-a); three circulating pumps(5,6,7). Dye-containing wastewater is pumped into the recycling tank(1-a) of the first reactor and then circulated through the packed tower(1) of the first reactor by the circulating pump(5) undergoing counter-current contact with ozone gas stream upward through the bottom of the packed column, a portion of the wastewater being overflown to the next recycling tank(2-a) of the second reactor performing the same sequence as the first reactor. Ozone flows into the bottom of the packed tower(3) of the last reactor and come out form the top of the tower(3) then to the bottom of the second and to the first one.
