A separation method specific for solvent-refined coal was developed. The method is based on the use of SRC-coated Fluoropak-basic alumina columns and can be applied in two ways. The first variant involves a switching column technique and provides solubility characteristics and compound-class composition of SRC without the need to evaporate solvents and redissolve fractions. The second variant permits a rapid separation of SRC into compound classes using a dual column system. Model compounds representing various compound classes were used to evaluate the procedure. In this paper a low-ash Wyodak SRC was used to illustrate the capability of the method. However, the method was successfully used for separation of various SRC samples.
