Abstract

As industry and medicine developed, many people became interested in the quality of life. As the concern for health became higher, vegetarian or vegetable oils became more popular than meat. With the development of processes primarily using nickel catalysts today, the shelf life of vegetable oils has increased and mobility has become more convenient. Currently nickel catalysts for the curing of oil are dominated by foreign companies in the world market. On the other hand, the mass production technology of domestic nickel catalyst is backward, and the entire amount is imported from foreign countries. Therefore, there is a need for active research and development of a catalyst that can be commercialized in korea. In this study, nickel as a main active catalyst was used as a base for hydrogen curing reaction, and the effect of rare earth on catalytic activity was investigated. A certain amount of rare earths could induce the dispersion of nickel to increase efficiency and use as co-catalyst.

산업과 의학이 발전되면서 많은 인구는 삶의 질에 관심을 가지게 되었다. 건강에 대한 시각이 높아지면서 육류보다 채식 또는 식물성 오일을 선호하게 되었다. 오늘날 주로 니켈 촉매를 사용한 공정이 개발되면서 식물성 오일의 보존기간이 늘어나고 이동성이 편리해졌다. 현재 유지경화용 니켈 촉매는 외국기업이 세계시장을 장악하고 있다. 한편, 국내 니켈 촉매의 대량 생산 기술은 퇴보 되어 전량 외국에서 수입하고 있는 실정이다. 따라서 활발한 기초연구가 필요하고 국내에서 상용화 할 수 있는 촉매개발이 필요하다. 본 연구는 수소화 반응으로부터 유지경화에 기반이 되는 니켈을 주 활성 촉매제로 사용하였고, 희토류가 촉매의 활성에 주는 영향을 알아보았다. 일정량의 희토류는 니켈의 분산을 유도하여 효율을 증가시키고 조촉매로써 사용이 가능하였다.
