Abstract
This invention provides a method for solubilizing wood or wood and coal mixtures in a highly aromatic refinery petroleum solvent to produce homogeneous compositions which have a flowable pitch-like consistency at ambient temperatures. The invention compositions are directly applicable as liquid fuels, or can be further processed into other desirable products.
Claims9
A process for liquefaction of solid carbonaceous materials which comprises forming a slurry by admixing comminuted wood with a petroleum solvent selected from thermally stable petroleum refinery FCC main column bottoms and TCC syntower bottoms having a boiling point between about 450.degree. F and 1100.degree. F, and heating said slurry at a temperature in the range between about 350.degree. F and 850.degree. F for a period of time sufficient to convert the slurry into a homogeneous composition which has a flowable pitch-like consistency at standard temperature.
