article{osti_, title = {Gasification of brown coal for the generation of synthesis gas}, author = {Femmer, U and Lambertz, J and Theis, K A}, abstractNote = {The HighTemperature Winkler (HTW) process has been developed by the Rheinische Braunkohlenwerke AG (Rheinbraun), Cologne, to produce synthesis gas (CO + H/sub 2/) as well as lowBTU gas.
The HighTemperature Winkler gasifier, shown schematically in Figure, is a dryfeed, pressurized, fluidizedbed, dryash gasifier. The HTW process was developed by Rheinbraun in Germany during the 1920s to utilize coal with a small particle size and that was too friable for use in existing fixedbed gasifiers.
Commercial gasifiers of GE Energy, CBI EGas™ and Shell SCGP are examples of entrainedflow types. Fixedor movingbed gasifiers include that of Lurgi and British Gas Lurgi (BGL). Examples of fluidizedbed gasifiers include the catalytic gasifier technology being commercialized by Great Point Energy, the Winkler gasifier, and the KBR ...
"Gasification is a process of thermal conversion of solid carbonaceous materials into a gaseous fuel called syngas. Coal gasification is an efficient technology for a range of systems for producing lowemission electricity and other highvalue products such as chemicals, synthetic fuels, paper presents the HighTemperature Winkler (HTW) gasification process, which is designed to ...
The HighTemperature Winkler (HTW) process developed by Rheinbraun is a fluidisedbed gasification process particularly suitable for various types of lignite, other reactive and ballastrich coal types, biomass and different types of pretreated residual waste. Depending on the application, the HTW process can be used for efficient conversion ...
Objective is a commercialscale coal gasification facility producing clean mediumBtu gas (300 billion Btu/day) from 20,000 tons/day of bituminous coal. The process was narrowed down to either the Texaco process, the KoppersTotzek process, or a combination of those two. This document is a summary description of the plants for both processes.
This is also the case for the Lurgi pressure gasification process carried out in a mechanically agitated solid bed at ca. 1200°C (as used in Sasolburg in South Africa), for the KoppersTotzek process in which the coal is used in the form of flyash (atmospheric pressure, 1400 to 1600°C) and for the Winkler process operating with a ...
The High Temperature Winkler (HTW™) process is a variant of the fluidized bed gasification processes. It originates from the Winkler process originally developed by Fritz Winkler in the 1920's. The intention was to develop a process to produce syngas with increased amounts of hydrogen and carbon monoxide.
HTW™ process. The High Temperature Winkler (HTW™) process is a variant of the fluidized bed gasification processes. It originates from the Winkler process originally developed by Fritz Winkler in the 1920's. The intention was to develop a process to produce syngas with increased amounts of hydrogen and carbon monoxide.
For example, the Winkler fluidizedbed process was developed in 1926 by Rheinbraun AG in Germany for gasifying lignite coal, the Lurgi dryash gasification technology was developed by Lurgi GmbH in the 1930s, and the KoppersTotzek entrainedflow process was developed in the 1940s.
Coal gasification is recognized as the core technology of clean coal utilization that exhibits significant advantages in hydrogenrich syngas production and CO2 emission reduction. This review briefly discusses the recent research progress on various coal gasification techniques, including conventional coal gasification (fixed bed, fluidized bed, and entrained bed gasification) and relatively ...
