Correlation between hydrogen yield and product distribution in algae conversion through an isopropanol/water system

This work reports a catalytic decomposition of algae to bio-oil over an isopropanol and water mixture system. The H 2 yield was adjusted by changing the ratio between isopropanol and water. In this system, the introduction of formic acid was helpful to extend the yield range. Five noble metal suppor...

Description
Summary:This work reports a catalytic decomposition of algae to bio-oil over an isopropanol and water mixture system. The H 2 yield was adjusted by changing the ratio between isopropanol and water. In this system, the introduction of formic acid was helpful to extend the yield range. Five noble metal supported catalysts were applied and Rh/C was proved to give the highest oil yield. A correlation was established between hydrocarbon yield and H 2 yield. It was useful in predicting product distribution and helping to obtain desired products. EA, GC and GC-MS were applied in product analysis. Catalytic liquefaction of algae to bio-oil through an isopropanol/water system and correlation between hydrogen selectivity and product distribution.
