초록

일산화탄소와 수소로부터, 혼합알콜 합성반응을 K₂CO₃를 조촉매로 하는 MoS₂ 게 촉매상에서 수행하여, 반응활성 및 선택도에 미튼 조촉매 함량, 온도, 압력 등의 영향을 고정층의 고압 촉매 반응기에서 조사하였다. 제조된 MoS₂ 촉매는 활성에 있어서 우수한 안정성을 보였으며 C₁-C₆ 범위의 직쇄상 알콜에 대해 높은 선택도를 나태나었다. 또한 알콜 생산량에 대한 최적 반응 조건은 조촉매 함량 17wt%, 온도 300℃이었으며, 압력의 증가는 알콜 수율을 증가시켰다. 이 때 알콜 생성물의 탄소수에 따른 분포는 전형적인 Schulz-Flory 분포를 만족하였다.

The effects of K₂CO₃ content,reaction temperature and pressure on the activity and selectivity of MoS₂ catalyst for the catalytic hydrogentation of CO producing mixed alcohols were investigated in a high pressure fixed bed reactor. A MoS₂ catalyst promoted with K₂CO₃ showed stable activity and high selectivity for C₁-C₆ linear alcohols. The optimal conditions of this reaction system in terms of alcohol productivity were 17wt% K₂CO₃ content on the catalyst and 300℃ of reaction temperature. The amount of alcohol production depends on the reactor pressure : the higher the reactor pressure, the higher the alcohol yield. The product distribution of C₁-C₆alcohols was well correlated by the Schulz-Flory distribution.
