초록

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.

청구항

1. A method of forming syn gas comprising devolatilizing a feed material in a controlled manner at a first temperature low enough to react oxygen in said feed material without causing pyrolysis thereby forming a char; subsequently combining said char with steam and passing said steam and char through a heated reaction vessel at a second higher temperature to form syn gas.2. The method claimed in claim 1 wherein heat is provided to said heated reaction vessel by combustion of produced syn gas.3. The method claimed in claim 2 wherein said char and steam ar...
