Equipment for the simultaneous removal of saturated species from coal liquefaction solvents by thermal cracking and the delayed coking of pitch has been constructed, commissioned and put into operation. Experimental programmes on satcracking alone, on coking alone and on simultaneous coking and satcracking have been completed. The yields of products from satcracking depend only on the extent of saturates breakdown and are otherwise independent of processing conditions. The degree of saturates reduction during simultaneous coking and satcracking was sufficiently large to allow this technique to be used to control the saturates content of coal liquefaction process recycle solvents. Coke yields from both coking alone and from simultaneous coking and satcracking were not affected by processing conditions in the range studied, although the coke volatile matter content decreased with increasing coking temperature. Coke yields were higher during simultaneous operation than while coking alone. The coke produced would be an environmentally superior solid fuel, and its physical structure suggests that it would be an excellent feedstock for the production of premium-grade electrode coke.
