ABSTRACT:
A vibrating bed pyrolysis system has a vibrating bed which is supplied with hot solid particles. Dry coal particles are rapidly heated by the hot solid particles to drive off hydrocarbon vapors. The vapors are condensed in a jet condenser, and products are flowed to a header tank. A portion of the liquid product is stored at room temperature for later use. A small portion of the liquid product is pumped from the header tank and cooled to ambient temperature and is sprayed in the jet condenser, which is positioned above the vibrating pyrolysis bed. A dryer bed vibrated by the same vibrating machine which vibrates the pyrolysis bed is supplied with hot solid particles and the crushed coal. Moisture in the coal particles is evaporated, and water vapors entrain coal fines before the coal particles are passed to the pyrolysis bed. The hot solid particles are taken from a fluidized bed combustor and are returned to the combustor with the coal char particles by entrainment into the gas lift system. The water vapor and entrained coal fines from the dryer flow into the combustor and a non-condensable gaseous portion of the product flows from the header tank to the combustor.
