Abstract:
본 발명은 플라즈마-촉매를 이용한 메탄 전환반응에 있어서, 단순히 촉매의 직경을 조절함으로써 종래와 같이 플라즈마 파라미터 제어 등의 복잡한 조작 없이도 수소(H 2 ) 및 C 2 ~C 4 올레핀과 같은 생성물을 효율적으로 생산할 수 있다. 이와 동시에 플라즈마 존재 하의 반응에 필요한 전기에너지를 감소할 수 있다는 점에서 에너지 효율적이다.
Abstract:
The present invention relates to a device for performing C-H bond cleavage using a plasma-catalyst; and to a method for manufacturing hydrogen (H_2) and/or hydrocarbon having two or more carbon atoms. The present invention increases the conversion rate of methane by using inert gas as carrier gas and using a gas separation membrane module in C-H bond cleavage reaction. Also, the present invention enables an economical process by separating and recovering inert gas among discharged gas and reusing the inert gas.
Abstract:
Carbon dioxide absorbent containing a hetero metallic oxide porous material formed by uniformly mixing carbon dioxide absorbing metallic oxides with support metallic oxides is provided. Also, a manufacturing method of carbon dioxide absorbent, which comprises a step of forming a mixed solution which a precursor of carbon dioxide absorbing metallic oxides and a precursor of support metallic oxides are mixed; and a step of obtaining a precipitate by making the mixed solution react by a liquid-phase method; and a step of obtaining a hetero metallic oxide porous material by firing the precipitate, is provided.
