  abstract: Wet comminuted methanol-lignite suspensions were studied in an effort to understand the interaction between the two species. Examination of liquid to solid ratio, particle size, moisture content, blending time and length of storage found only a relationship between storage time and fractional conversion in blended methanol-lignite suspensions. Methanol to lignite weight ratios greater than 10-20 had an effect on fractional conversion. Hydrogen ions were found to be generated from carboxylic acid and hydroxyl structural sites. Reaction monitoring also directed attention to the first order diffusion of hydrogen ions from the suspended bed to the liquid phase. Analysis of the products indicated that veratramine and germine-like saturated cyclic structural components of lignite are possibly extracted by methanol. Dimethoxymethane was found to be in the distillate of the suspension. Several types of compounds were found to be extracted by the methanol. The nature of these materials depended on whether the methanol-lignite suspension was pulverized or not.
