Abstract
In the hydrogenation of particulate coal in an ebullated bed reactor to produce hydrocarbon products, the improvement which comprises removing the coarser unreacted particulate from the recycled residiuum stream from the reactor by a liquid cyclone separation, recycling the overhead stream from said cyclone separation to the reaction zone, removing finer particulate solids from an additional liquid residiuum stream and also providing a net filtrate stream which is distilled to produce hydrocarbon vapor and liquid streams and combining said liquid stream with liquid resulting from condensation and fractionation of overhead vapor from the reactor to produce a synthetic crude oil.
