Gasification is a flexible, reliable and clean energy technology that converts materials containing carbon-i.e. coal, petroleum coke, biomass or waste-into synthesis gas (syngas). The syngas can then be used to produce electricity or be further processed to manufacture chemicals, fertilizers, liquid fuels, substitute natural gas, or hydrogen. Building upon the success of the authors' earlier work, the Handbook of Gasification is a comprehensive treatment covering principles, technologies, the worldwide market, gasification of woody biomass and mixed solid wastes, microbial gasification, Fischer-Tropsch and the biofuels refinery. Emphasis will be placed on biofuels and renewable resources.
