Abstract

Hydrogen production via steam reforming of bio-oil from algal biomass over fast pyrolysis with commercial catalysts was carried out. Aqueous bio-oil obtained by phase separation from a crude oil over fast pyrolysis was used as a reactant and comparison studies for activity over different catalysts (FCR-4-02, POS-7, Cat. A, RUA), reaction temperature, and steam/carbon (S/C) ratios were performed. Experimental results showed that different catalytic activities were observed with different S/C ratios and catalyst composition and the highest hydrogen yield of 70% was obtained with a POS-7 catalyst at a S/C ratio of 10 and 1073 K.

해조류 유래 급속열분해를 통해 생성된 바이오오일로부터 수소가스를 생산하기 위해 상용 개질 촉매를 사용하여 수증기 개질 반응을 수행하였다. 반응원료로 급속열분해로부터 생성되는 crude 바이오오일의 상분리를 통해 얻어진 수용액상의 바이오오일이 사용되었으며, 상용 개질 촉매(FCR-4-02, POS-7, Cat. A, RUA), 반응온도 및 수증기/탄소(S/C) 비율에 따른 수증기 개질 반응의 활성을 비교 연구하였다. 실험 결과 원료의 S/C 비율과 촉매의 구성성분에 따라 반응활성이 크게 달라지는 것이 확인되었으며, 특히 POS-7 촉매를 사용한 1073 K, S/C 비율 10의 조건에서의 수증기 개질 반응에서 가장 높은 수소 수율(70%)이 확인되었다.
