Abstract
MCM-41 촉매를 이용하여 일본 낙엽송의 열분해 바이오 오일의 촉매 개질 반응을 수행하였다. MCM-41 촉매는 바이오 오일의 불안정성의 원인중 하나인 산소를 H2O, CO, CO2의 형태로 제거하여 개질 전의 오일보다 더 안정한 오일을 생성하였다. MCM-41 촉매는 무촉매 반응에 비해 경제적 가치가 높은 페놀류 화합물의 생성량을 증가시켰다. 특히 Si-MCM-41 촉매에 비해 산점의 양이 많은 Al-MCM-41의 경우 촉매 활성이 더 우수하였다. 또한 촉매와 일본 낙엽송을 직접 혼합한 것보다, 바이오 오일이 촉매층을 통과했을 때 더 나은 개질 결과를 얻을 수 있었다.
Catalytic upgrading of pyrolytic bio-oil produced from Japanes Larch was carried out over MCM-41 catalyst. Oil with enhanced stability was produced by the MCM-41 catalyst due to transform oxygen known as a main cause for the instability of bio-oil into H2O, CO and CO2. In addition, the MCM-41 catalyst produced the larger amount of phenolic compounds in the pyrolytic bio-oil product compared with that in the bio-oil produced without catalyst. Especially, the catalytic activity of Al-MCM-41 for the bio-oil upgrading was higher than that of Si-MCM-41 because Al-MCM-41 has the larger amount of acid sites. Also, the better reforming result was obtained when pyrolytic bio-oil vapor passed through catalytic layer rather than Japanese Larch was mixed with catalyst directly.
