Based on a survey reported for 2003, there are 163 commercial gasification projects worldwide consisting of a total of 468 gasifiers.4 More than 120 plants began their operations between 1960 and 2000 with the majority (more than 72 plants) commissioned after 1980. Up to 34 new plants are at various stages of planning and construction. 

Texas lignite to generate MBG which would be piped to the Houston area for fuel and feedstock use. These studies have included the testing of Texas lignite in commercial gasification units located abroad.

Commercial Gasification Facilities Dedicated to Hydrogen Production... 

An extensive review of gasifier manufacturers in Europe, USA and Canada (10) identified 50 manufacturers offering commercial gasification plants from which ... 

In June 2004, GE acquired the assets of Chevron Texaco s gasification technology business. To date, more than 65 commercial gasification facilities using GE technology are in operation or advanced development stages. 

Research will be conducted in the apparatus described in this paper, and also in larger fluidized bed (100,000 BTU/hr) and fixed bed downdraft (1 x lCr BTU/hr) reactors. These two larger reactors better approximate commercial gasification chemistry in that the process heat is supplied internally by partial combustion of the biomass feedstock. 

This process produces low or medium Btu gases from wood and wood wastes, agricultural residues and MSW. Processing these synthetic gases with water can produce ammonia, methanol, or hydrogen. Commercial gasification systems exist, but their widespread use has been limited by hauling distances for the feedstock. 

Brief descriptions of commercial gasification processes can be found in the literature 4-8 gasification with steam (Exxon process), gasification with oxygen or air (Koppers-Totzek and Prenflo processes), and gasification with steam/oxygen or air mixtures (Shell, Winkler and Texaco processes). 

Table 3-2 summarizes the commercial gasification plants that Lurgi has built and licensed (1). The following five plants, which use 115 gasifiers, are currently in operation ... 

This look at synthetic fuels is restricted to coal gasification, as mentioned above. The present generation of commercial gasification processes includes three, all German, and all designed for chemical feedstock, rather than for fuel.
