Dual-fluidized-bed-gasification
Description of the Technology
With the dual-fluidized-bed-gasification, the basic idea is to spatially separate the gasification- and combustion reaction in order to obtain a largely nitrogen-free product gas (without the use of oxygen). The gasification takes place at surrounding pressure with steam as a gasification medium.
The generated product gas can be used to produce energy sources such as hydrogen, synthetic natural gas, gasoline, diesel, kerosene, electricity and also heat.
In addition to classical combustion, solid and liquid, carbon-containing substances can also be converted via a thermochemical transformation into a secondary energy carrier - the synthesis gas or also product gas - which has considerable advantages over combustion in terms of handling and further conversion possibilities in useful energy.
In this case, the same conversion processes happen, that are also given during combustion. The individual stages of the thermochemical transformation, however, are realized separately from each other spatially and temporally.
Due to the increasing global demand for energy and the replacement of fossil fuels, it is becoming more and more important to convert many different raw materials and residuals with a high overall efficiency into several forms of energy. This is only possible with the help of this special thermochemical transformation, the gasification.

Of all gasification processes, dual-fluidized-bed-gasification (DFB technology) is recognized as the most mature process worldwide.
