Beschreibung
Zusammenfassung:	The present invention provides a process and apparatus for converting feedstock comprising biomass and/or carbon-containing solid waste material to synthesis gas. The process comprises supplying a densified and pressurized feedstock to a gasifier comprising a fluidized bed zone and a post-gasification zone and contacting the feedstock with a gasification agent. Recovery and purification of the synthesis gas is then carried out involving the recycling of CO2 back to various stages in the process. The apparatus is configured to carry out the process and comprises transport lines to recycle the CO2. The synthesis gas can be further processed to form renewable synthetic products and/or chemicals.
