Methods for producing feedstock for a fixed bed gasifier from finely-divided coal

Patent ·
OSTI ID:5697278
A process for producing a feedstock for a fixed bed gasifier from finely-divided coal by treating the coal in a first stirred semi-fluidized carbonizer reaction zone to produce particulate coal derived solids larger than the finely-divided coal charged to the first carbonizer and thereafter charging the particulate coal derived solids so produced to a second stirred semifluidized carbonizer reaction zone to produce particulate coal derived solids of a size consist greater than 1/4 inch which is charged to a fixed bed gasifier.
