ABSTRACT:
Disclosed is a process for obtaining liquids and gases from carbonaceous material, such as coal. The carbonaceous material is first treated with a gasification catalyst, and optionally a hydrogenation catalyst, and hydropyrolyzed for an effective residence time, below the critical temperature at which methane begins to rapidly form, to make liquid products. The resulting char is gasified in the presence of steam at a temperature from about 500.degree. C. to about 900.degree. C.
