초록
연속반응조에서의 수소생산에 대한 pH의 영향을 HRT 10시간으로 유지하고, pH 4.1부터 8.0까지의 범위에서 조 사하였다. 실험조건에서의 생성된 수소가스 성분은 41~71% 범위로 발생되었다. H2/CO2 비율은 pH 6.0 이상에서 는 크게 변화가 없었으나, 대체적으로 pH가 증가함에 따라 H2/CO2 비율도 증가하였다. 최대 수소생성수율은 pH 5.0에서 3.16 l/g sucrose이었다. Acetate 생성은 pH 증가에 따라 증가하였으나, butyrate 생성은 pH 증가에 따라 감 소하였다. 미생물량은 pH 증가에 따라 증가하였다.
Abstract
The influences of pH on hydrogen production were also investigated over the pH range from 4.1 to 8.0 at HRT 10 hours. The hydrogen content for the produced gas was changed from 41 to 71% with corresponding pHs throughout this experiment. The produced hydrogen/carbon dioxide ratio was not vary significantly up to 6.0, then steepenly increased with increases in the pH. The maximal hydrogen yield was found to be 3.16 l/g sucrose at pH 5.0. Acetate production yield increased with increased pH, but butyrate production yield decreased with increased pH. Biomass yield increased with increased pH.
