Abstract
The invention provides an improvement to a process for producing a diesel fuel from a medium heavy oil obtained from coal. The invention increases the amount of medium oil which can be used to produce diesel fuel while keeping the total yield of oil from the coal about the same. Thus, the fraction of the medium oil recovered is greater without altering the total yield of oil from the coal, and now amounts to about 80 to 85 percent of the total oil yield. Accordingly, the amount of light oil derived in this process becomes correspondingly smaller. Thus, the total oil yield is increased by about 4 to 6 percent compared with previously obtained results.
