9 Gasification Portfolio The HTW Gasifier HTW Gasification Pressurised, fluidised bed Temperature: C Pressure: bar Operates below ash melting point ideal for coals with high ash melting point, biomass, lignite, waste) Refractory Lined Gasification Chamber Cyclone Recycle Line Bubbling Fluidized Bed

10 Gasification Portfolio ThyssenKrupp Uhde acquires HTW Gasification Technology HTW goes back to 1926 (Winkler Gasification) HTW technology was previously owned by RWE/Rheinbraun ThyssenKrupp Uhde acquires the HTW technology with all IP rights and know-how from RWE in December 2010 Main target: low-rank feedstocks, in particular: coals with high ash melting points, brown coal, lignite, wastes

11 Gasification Portfolio Different feedstocks require different gasification technologies PRENFLO Entrained-Flow Gasification HTW (High-Temperature Winkler) Fluidised Bed Gasification Oil Gasification
