Fluidized Bed Reactor System for the Gasification of Waste Materials and Biogenic Residues

The conversion of various solid low-cost fuels into valuable gas with high energy content is attracting increasing interest within the chemical industry and the energy supply sector. For the gasification of carbonic fuels, fluidized bed processing based on the dual fluidized bed concept is utilized preferably. Dual fluidized bed gasification technology greatly intensifies the conversion of the solid fuels into a valuable product gas due to excellent heat transfer. The gained nitrogen-free product gas can be cleaned and utilized for heat and power production (steam or district heating), and can also be used for different chemical syntheses, to easily produce homogeneous transportable gaseous and liquid fuels. After gas cleaning steps, it is possible to produce hydrogen, hythane, Fischer-Tropsch diesel/kerosene, synthetic natural gas, and other chemicals like methyl alcohol. In addition, an enhanced gasification concept enables the in-situ capture of CO2 without the need for energyintensive downstream gas separation.
