The COED process - A review

Abstract

The COED-process, a fluidized-bed pyrolysis coal conversion technique, is described in considerable detail. Using Illinois 6 coal as feedstock for the process, the coal is taken through the pyrolysis stages to produce a raw pyrolysis oil. This oil is then filtered and hydrotreated to produce a synthetic crude oil - a syncrude. Further downstream processing of this syncrude is analyzed to produce a final hydrotreated and hydrocracked product capable of being used as a synthetic jet or motor fuel. This is the first of a series of reports intended to assess the worth of coal conservation process currently under development. This example is chosen because it is the only coal pyrolysis process where sufficient data are available in the literature for any sort of realistic evaluation.
