Title: Process for obtaining diesel fuels from tars. [solvent extraction and cracking]

Patent ·
OSTI ID:7102656

Process for obtaining valuable Diesel fuels from paraffin containing tar from solid carbonaceous material comprises topping the tar to remove constituents boiling below about 260/sup 0/C, subjecting the residue from the topping to treatment with a selective solvent which forms an extract portion containing in solution tarry components of the residue and a raffinate portion which contains paraffin, separating the extract portion and the raffinate portion produced by the treatment, filtering the raffinate phase at about 20/sup 0/C to separate crude paraffin wax, and cracking the oil thus obtained.
