Severson, D E

Tests in which lignite was dried in the batch autoclave with solvent indicated that there was no generation of solvent type material. Work on hydrogenation of Solvent Refined Lignite (SRL) indicated that the highest yields of gases and distillable products were obtained at solvent: SRL ratio of 1:1. Fast fluidization of -100 mesh catalyst particles was achieved at air velocities of 4.33 to 7.48 ft/s at feed rates to 5 lb/h giving bed densities as high as 15 lb/ft/sup 3/. Effort was directed towards completion of the Process Development Unit for liquefaction of lignite to Solvent Refined Lignite and the SRL hydrogenation unit. (DLC)
