Method and apparatus for producing synthesis gas from carbonaceous materials

摘要

A method of producing syn gas from biomass or other carbonaceous material utilizes a controlled devolatilization reaction in which the temperature of the feed material is maintained at less than 450° F. until most available oxygen is consumed. This minimizes pyrolysis of the feed material. The method and apparatus utilizes the formed synthesis gas to provide the energy for the necessary gasification. This provides for a high purity syn gas and avoids production of slag.
