- In the HYGAS pilot plant gasification reactor, fine particles from each reactor stage become entrained in the gas and are carried into the exit-gas cyclone and are removed from the gas. Thus, the dust removed by the pilot plant cyclone includes particles from the steam-oxygen-gasification fluidized bed, the second-stage hydrogasification fluidized bed, the first-stage hydrogasification entrained reactor, and the slurry drier fluidized bed. For an understanding of the process, it is desirable to estimate the amount of feed coal carried out of the reactor from the slurry drier bed. To fill this need, we have developed a petrographic method for determining the feed coal content of samples of dust collected from the cyclone. The method was developed on samples obtained when the pilot plant was operating on lignite, but it should also be applicable to samples from the processing of other ranks of coal.
