불균일계 촉매를 통한 프로판 고부가화

국문 초록 (Abstract)

본고에서는 산업적으로 효용가치가 막대함에도 불구하고 아직까지 에너지원으로만 사용되고 있는 프로판을 불균일계 촉매를 사용하여 고부가화시키는 방안에 대하여 다루고자 한다. 특히 프로판으로부터 생산 가능하면서도 경제적 가치가 뛰어난 물질이라고 판단되는 프로필렌 및 아크릴로니트릴을 중심으로 서술하였다. 프로필렌의 경우 지금까지 프로판 탈수소화반응을 통하여 제조 가능하였으나 열역학적인 한계를 극복하기 위하여 산소, 이산화탄소 등의 산화제를 이용하는 산화적 탈수소화반응에 대한 현황을 논하였다. 한편 암모니아첨가 산화반응을 통하여 제조할 수 있는 아크릴로니트릴은 지금까지 출발물질로서 프로필렌을 사용하였으나 저렴한 가격에 공급이 가능한 프로판을 원료로 사용하는 경우 경제적 가치가 뛰어나다. 최근 프로판의 암모니아첨가 산화반응에 성능이 우수한 MoVTeNbOx 촉매가 개발되었지만 그에 대한 추가 연구가 필요한 실정이다. 상기 반응들에 있어서 최대의 관건은 성능이 우수한 불균일계 촉매를 개발하는 것으로서, 촉매 개발 시 파일럿 규모 이상의 공정에 적용시킬 수 있을 것으로 전망한다.

다국어 초록 (Multilingual Abstract)

In this review we discussed the effective ways to catalytically derive value-added chemicals from propane which has been utilized only as an energy source so far. Among various propane-derived products, the most valuable chemicals such as propylene and acrylonitrile were mainly focused herein. Propylene could be manufactured through oxidative dehydrogenation of propane using O₂, CO₂, etc. as an oxidant for the purpose of overcoming thermodynamic limitations of propane dehydrogenation. On the other hand, propane ammoxidation would be an alternative to propylene ammoxidation for producing acrylonitrile since propane is much cheaper than propylene as a starting material. Although effective MoVTeNbOx catalysts have been developed for propane ammoxidation in recent years, more detailed studies should be thoroughly performed. In carrying out both oxidative dehydrogenation and ammoxidation of propane for a long period, the most critical issue is definitely considered to find out the most active and selective catalysts, which makes it possible to commercialize both reactions into economically viable processes.
