Because of the increasingly uncertain availability of supplies of petroleum-based feedstocks, the need to develop alternative sources of petrochemical feedstocks has become generally recognized. Coal, lignite, and peat could be used to generate feedstocks at prices that are competitive in current markets. In addition to being applied in domestic production, processes yielding petrochemical feedstocks from non-petroleum raw materials would be of interest to developing nations, which now must import petroleum for transportation fuels and petrochemicals. At IGT, a process to produce pipeline gas, ethane, blending gasoline constituents, and aromatic chemicals such as phenols, cresols, and naphthalene from coal, lignite, or biomass is being developed. Depending upon the raw material and processing conditions chosen, chemicals such as acetic acid, propionic acid, methanol, and acetone can be obtained as well. In this process, the HYFLEX process, carbonaceous raw materials are cocurrently heated with hydrogen or another gas in an entrained-flow reactor to pyrolysis temperatures, which produces a slate of products that can be varied by choosing different operating pressures and cracking severities.
