A catalytic gasification process and system for producing medium grade BTU gas including a gasification reactor having an inner air gasification zone, an outer steam gasification zone, a synthetic coal reaction zone, and an upper lime treating zone. The process and system of the present invention further includes a synthetic coal heating vessel which provides superheated recycled synthetic coal to the gasification reactor and a limestone treating vessel which provides superheated air and CO2 to the gasification reactor. The novel process and system of the present invention provides for the production of a medium grade BTU gas and several commercially valuable by-products with virtually no solid or liquid waste products. |
