Technological Pathways and Economics of DME-production from "Dry" Biomass

T. Schulzke, C. Unger, K. Girod & T. Jänisch
Two different concepts for large­scale production of dimethyl ether (DME) from wood were developed. These concepts are based around wood gasifiers and single­pass DME synthesis reactor. The main differences between the two concepts are the two gasifiers adopted. Specifically one uses a steam blown atmospheric circulating fluidised bed (CFB) gasifier in comparison to a pressurised (CFB) gasifier utilising a mixture of steam and oxygen as gasifying agents used in the other. Results of the simulations...
