마이크로파에 의한 동·식물성 폐유지로부터 바이오디젤 제조 = Preparation of Biodiesel Using Microwave Energy from Waste Animal-Vegetable Oils

국문 초록 (Abstract)

마이크로파를 적용한 전이에스터화 반응에 의해 식물성 유지와 동물성 폐유지, 그리고 동·식물성혼합 폐유지로부터 바이오디젤을 제조하였다. 동·식물성 유지 원료에 대한 전처리 조건은 상온에서 30분간 교반시키며 숙성시킨 경우, 반응 후 바이오디젤 제조수율이 가장 높았다. 마이크로파를 이용하여 식물성 유지와 동물성 폐유지로부터 제조한 바이오디젤의 수율은 수산화칼륨 촉매에서 약 80 %로 가장 높았다. 이 공정과 촉매조건에서 동·식물성 혼합 폐유지 원료에 대한 바이오디젤 수율도 이와 비슷하게 77 % 정도로 얻어졌다. 마이크로파를 적용한 회분식 반응기에서 바이오디젤 제조공정은 반응 시작 후 5분이 경과하면, 바이오디젤 생성 최고 수율에 도달할 정도로 반응 속도가 매우 빨랐다.

Biodiesel was prepared using a microwave energy from vegetable oil, animal tallows, and a mixed animal-vegetable waste oil. Microwave was induced as an energy to the batch-type reactor with 2450 MHz of wavelength and 1 kW of power. In the comparison of pretreatment conditions to the feedstock for biodiesel production, the highest yield of biodiesel was obtained in the pretreatment condition of aging with stirring for 30 min at 25 ℃. The highest yield of biodiesel was obtained on the KOH catalyst about 80 % in the transesterification using microwave energy. It was also obtained about 77 % from the mixed animal-vegetable waste oil in the reaction on the KOH catalyst. The reaction equilibrium reaching to maximum yield of biodiesel was fast as 5 min in the transesterification using microwave energy.
