A study on the mass production of bio-hydrogen from carbon monoxide |
| 초록 |
In this study, a microbial fermentation process was developed to produce H2 from CO. For this, continuous fermentation of Thermococcus onnurineus was carried out in a 2.5 L stirred tank bioreactor with varying process variables. It was observed that if CO was not limited, both the cell growth and H2 production rate (HPR) were linearly correlated with dilution rate. The HPR has also been observed to increase linearly with CO supply rate or agitation speed, mainly due to an increase of gas-liquid mass transfer rate. Based on the lab-scale results, the pilot study was performed in a 1,000 L gas-lift type bioreactor using CO-containing industrial off-gas. As a results of continuous cultivation of T. onnurineus on steel mill by-product gas, the HPR reached a maximum value of 250 mmol/L/h, which corresponds to a daily H2 production of 50 Nm3. |
