摘要The plausible solution of non-renewal energy shortage and serious fossil fuels air pollution is developing renewable energy. The rapid development of biodiesel production faces a serious problem of generating large amount of byproduct, crude glycerol. Further converting the crude glycerol into utilizable compounds is economically unpractical. Utilizing crude glycerol as a substrate for photo-fermentative hydrogen production by Rhodopseudomonas palustris was attempted. However, the efficient production of hydrogen was not achieved.

In this study, a selected magnetic photocatalyst will be added into Rhodopseudomonas palustris photo-fermentative culture to enhance hydrogen and poly-β-hydroxybutyrate (PHB) production in crude glycerol medium. The physical, chemical and biological parameters for photo-enhanced hydrogen production by the magnetic photocatalyst-R. palustris system in a laboratory-scale unit (0.5 liter) will be optimized to achieve the best hydrogen and PHB production, and crude glycerol utilization. To conduct a feasibility study, a pilot-scale device (20 liters) will be designed, fabricated and tested for hydrogen and PHB production. Based on the results obtained in laboratory-scale unit, the conditions for hydrogen and PHB production, and crude glycerol utilization performance of the magnetic photocatalyst-R. palustris system in the pilot-scale device will be fine-tuned to demonstrate the feasibility of large-scale operation.
