A continuous flow wood processing technology for extracting lignin from woody plant material and converting the delignified cellulosic residue to crude bio-oils is provided. Wood is chipped before processing starts and fed into a lignin extractor. The lignin extractor uses ethanol at high temperatures to dissolve the lignin with counter current material contactors. The ethanol containing dissolved lignin is removed from the lignin extractor, the dissolved lignin recovered, the ethanol and residual heat being recycled into the lignin extractor. The delignified cellulosic pulp is removed from the lignin extractor and subjected to a milling operation to convert the pulp into a smooth sludge for entry to a bio-convertor by a super critical water process. The product from this convertor is hydrocarbon sludge with a principal component being a kerogen. In a separate process crude oil is extracted from this sludge and the residue is prepared as a high phosphate Fertilizer.
