The SGT PROCESS
Gasification - gasification of coal - is a process of processing organic materials and fuels based on carbon monoxide - CO, hydrogen - H2 , and carbon dioxide - CO2. This is achieved by reaction at high temperature (>700 oC), without burning in controlled amount of oxygen and water vapor. The result is a gas mixture called syngas (synthesis gas). The synthesis gas itself is a fuel. The process of gasification is regarded as a renewable energy process, when the biomass is subject to gasification.
In the gasification process, the carbon in atomic state reacts with steam, and hydrogen and carbon monoxide are the resulting products of the reaction C + H2O -> H2 + CO
At present, there are several gasification technologies in commercial installations in the world. The amount of processed raw material per year starts from 20 000 tonnes for small installations (generating 1.0 MW + 1.8 MWth to 5 MWe + 9 MWth) until installations processing hundreds of thousands tonnes of this raw material per year.
