INTRODUCTION
The growing emphasis on coal liquefaction technology has resulted in increased interest in the development of methods to determine the composition of liquids produced by the process. This information can facilitate understanding of the relationship of the occurrence of various chemical species to the structure and reactivity of the parent coal. This report describes an ion pair liquid chromatography study of the light oil fraction from the liquefaction of lignite with CO and H2 at 460°C and 27.6 MPa.
The light oil is a gas condensate collected in a water-cooled receiver at atmospheric pressure. The sample studied was collected on the 30th recycle pass of a Beulah lignite liquefaction test using anthracene oil as start-up solvent. Based on MAF coal, the light oil represents about 19% of the yield. A detailed description of the GFETC continuous process unit has been published previously (1).
