A coal conversion process wherein the coal is carbonized in a series of fluidized beds to produce gas, an oil/tar fraction 30 containing suspended solids which can be hydrogenated 32A or 32B to produce a commercially useful product, and highly reactive char 4 which is gasified with steam in a gasifier 5, in which substantial advantages are obtained, both in capital and operating costs, by separating the solids and the heavy oil component from the oil/tar fraction and recycling 36 or 52 them to the gasifier. <IMAGE> |
