Abstract: This invention relates to the conversion or hydrotreatment of petroleum or coal derived liquids in a novel ebullated-bed reactor system. The novel processing scheme results in a much simpler and less costly (investment and annual operating) ebullated-bed reaction system through the elimination of the high pressure, high temperature separator, hydrogen purification plant, and recycle gas compressor as well as a smaller hydrogen make-up compressor all resulting in substantial operational and construction efficiency.
