SLOT PYROLYSIS REACTOR AND METHOD OF PYROLYSIS

摘要

Apparatus for conducting the flash pyrolysis of a primary material, particularly coal, and employing a secondary material, particularly hot char, as a heat source, comprises means forming a rectangular slot for injection of a stream of particulate primary material into a substantially rectangular-section reactor or pyrolysis chamber, wells positioned on opposite sides of the pyrolysis chamber and in communication therewith, for introduction of fluidized secondary material into the pyrolysis chamber for admixture therein with and for heating the stress of primary material, a cylindrical separator chamber communicating with the pyrolysis chamber for receiving pyrolysis products through a tangential inlet, a solids outlet conduit from the separator chamber positioned about 90.degree. around the circumference of the separator chamber from the tangential inlet, and a perforate gas receiver in the separator chamber. A process for flash pyrolysis of a particulate primary material, such as coal, which comprises passing a high velocity stream of such material through a rectangular slot to form a slot jet or sheet of such particulate primary material having a rectangular cross section, injecting such slot jet into a substantially rectangular pyrolysis zone, introducing a fluidized particulate secondary material, such as char, into such pyrolysis zone, mixing the particulate primary material and particulate secondary material in the pyrolysis zone, and pyrolyzing the mixture, reducing the rectangular cross section of the resulting stream of pyrolysis products tangentially introducing such stream of pyrolysis products tangentially into a cylindrical separator zone, removing solids rapidly from the separator zone after said stream has passed around only a fraction, e.g. one quarter, of the circumference of the separator zone, and removing gases, through a perforated as receiver, from the separator zone.
