Abstract
A process is described for the flash pyrolysis of a high rank caking coal in a pyrolysis chamber in which the coal passes through a tacky state during flash pyrolysis. According to the novel feature, before entering the pyrolysis chamber, the particles of high rank caking coal are blended with a diluent comprising a finely ground non-caking coal, whereby agglomeration and caking of the high rank coal is prevented during flash pyrolysis.
