ABSTRACT
Fossil fuels such as coal, oil, and natural gas are used to generate a very large proportion of the electricity in the world. Firing with these fuels gives rise to carbon dioxide, which is a greenhouse gas discharged to the atmosphere. So there is keen interest in reducing the CO
emissions from sources such as fossil fuels. On the other hand, the carbon dioxide generated in the combustion of biofuels is not considered to contribute to the net CO
content of the atmosphere, since it is absorbed by photosynthesis when new biomass is growing [1, 2].
