B. Mazumder, in Coal Science and Engineering, 2012 (e) Synthane process. Bureau of Mines (USA) developed this process for converting bituminous coal, Subbituminous coal and lignite to substitute natural gas (SNG). The process involves gasifying coal in a fluidized bed (816–982°C) upto 1000 lb/in 2 pressure to a raw gas containing CH 4, CO, H 2, CO 2 and water vapor.
Bituminous Coal an overview ScienceDirect Topics
The aromaticity of coal and coalified wood is greater in bituminous coals than in subbituminous coals (Hatcher, 1988 Cody, 1992). Analysis of bituminous coals using PYGC/MS also typically shows the presence of polynuclear aromatic ring systems that are absent in lignites (Hatcher and Clifford, 1997).

Bituminous coal contains 45%–86% carbon and has two to three times the heating value of lignite. Bituminous coal was formed under high heat and pressure.
What are the types of coal?
There are four major types (or "ranks") of coal. Rank refers to steps in a slow, natural process called "coalifiion," during which buried plant matter changes into an ever denser, drier, more carbon rich, and harder material. The four ranks are:
