Combustion and gasification of coal-algae blends have the potential of reducing the carbon footprint from combustion and gasification of coal alone. This paper presents results from an experimental study on pyrolysis and gasification of a Victorian brown coal and a marine algae, first these fuels alone and then as blends of 90:10 to 50:50 by mass. These experiments are conducted in a Thermogravimetric analyzer with steam-injection capability. In general, algae were found to be more reactive than Victorian brown coal during pyrolysis while coal was more reactive than algae during gasification. The reactivity of the coal-algae blends was found to be lower relative to coal alone during steam gasification. But as the pyrolysis and gasification characteristics remains in between the behavior of algae and coal, small percentage of algae can be blended with coal for gasification purposes.
