The Hynol Process was originally conceived to process biomass (wood and agricultural products) for the production of methanol with reduced CO{sub 2} emission. Effort has also been made to apply the process to municipal solid waste (MSW) feedstock. The Hynol Process in general can be applied to the use of any condensed carbonaceous material as feedstock. A basic feature of the Hynol Process is that natural gas is used as a co-feedstock with the condensed carbonaceous feedstock to produce a higher yield of methanol per unit feedstock than is obtained when using either feedstock alone in the conventional process for producing methanol. The reason for the improved yield is that the condensed feedstock has a deficiency of hydrogen compared to carbon, while natural gas has an excess of hydrogen compared to carbon. Thus, the co-feedstock of condensed carbonaceous material with natural gas yields the closest approach to and the optimizes the hydrogen to carbon content for producing the product methanol. Another feature of the Hynol Process is that it is a complete recycle system maximizing the mass and energy balance. In this paper we apply the Hynol Process to the co-processing of coal with natural gas.
