METHOD FOR TREATING INORGANIC MATERIAL CONTAINING OIL

摘要

PROBLEM TO BE SOLVED: To provide a method for treating an inorganic material containing oil which efficiently separates /extracts oil from the inorganic material containing oil and converts the oil into a fatty acid eater fuel, and recovers the adsorbing performance of the inorganic material to recycle it.

SOLUTION: The inorganic material containing oil is added with a lower alcohol and is pressurized and heated under the conditions of 240-350°C, 5-25 MPa and 5-60 min. Then the above inorganic material is pressurized and heated under the condition of the supercritical state of the lower alcohol, and a hydroxy compound (1-5C) expressed by a general formula R-OH is used as the lower alcohol, wherein R is a methyl group or an ethyl group. The lower alcohol of 10-200 parts by mass is added to the inorganic material containing oil of 100 parts by mass.
