초록
본 연구에서는 다양한 구조 유도제로 합성된 SAPO촉매를 이용하여 자일로오스의 탈수화 반응을 진행하였다. 구조유도제로는 테트라에틸암모늄수산화물(TEAOH), 디프로필아민(DPA), 디에틸아민(DEA), 몰포린(Morpholine) 그리고 디에탄올아민(DEtA)을 사용하였다. 촉매의 특성을 파악하기 위하여 질소 흡착-탈착 등온선, 암모니아 승온탈착(NH3-TPD), 그리고 승온산화분석(TPO)을 이용하였다. 구조 유도제로 몰포린(Morpholine)을 사용하여 제조한 SAPO-34를 촉매로 사용하였을 경우 사용한 촉매중에서 푸르푸랄 수율이 가장 높았다. 고체산 촉매의 외부 표면적과 산농도가 자일로오스의 탈수화 반응에 영향을 주는 것으로 나타났다.
We synthesized a variety of SAPO catalysts with various structure directing agents by the hydrothermal method and applied them to the D-xylose dehydration. Single or mixtures of organic amines, viz. tetraethylammonium hydroxide(TEAOH), dipropylamine(DPA), diethylamine(DEA), morpholine and diethanolamine(DEtA) were used as structure directing agents. The N2-isotherm, NH3-temperature programmed desorption(TPD) and temperature programmed oxidation(TPO) were conducted to characterize SAPO catalysts. Among tested SAPO catalysts, the SAPO-34 synthesized with morpholine showed the highest furfural yield. The external surface area as well as the surface concentration of acid sites appeared to affect the catalytic activity for the dehydration of xylose into furfural.
