<p>A coal conversion process wherein the coal is carbonized in a series of fluidized beds to produce gas, an oil/tar fraction containing suspended solids which can be hydrogenated to produce a commercially useful product, and highly reactive char which is gasified with steam in a gasifier, 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 them to the gasifier.</p> |
