Abstract
Apparatus for conducting the flash pyrolysis of a primary material, particularly coal, and employing a secondary material, particularly hot char, as a heat source, comprising a rectangular slot for injection of a stream of particulate coal, which communicates with a substantially rectangular reactor or pyrolysis chamber. Wells are positioned on opposite sides of the pyrolysis chamber and in communication therewith, for introduction of fluidized secondary material, particularly hot char, into the pyrolysis chamber for admixture therein with and for heating the stream of primary material, such as coal. The pyrolysis chamber has a transition chamber, and a cylindrical separator chamber communicates with the transition chamber for receiving pyrolysis products. The separator chamber is provided with a tangential inlet, a solids outlet conduit positioned about 90.degree. around the circumference of the separator chamber from the tangential inlet, and a perforate gas receiver. The process for flash pyrolysis of a particulate primary material, such as coal, utilizing apparatus as described above.
