SYSTEM AND METHOD FOR REFINING CARBONACEOUS MATERIAL

摘要

A system for refining carbonaceous material including a carbonaceous material feedstock unit including a first vibratory screen unit for sizing the carbonaceous material; a digestion unit including a digestion unit in communication with the carbonaceous material feedstock unit; and an acid feedstock unit in communication with the digestion unit for providing an acid mixture solution to the digestion unit including a source of H2O; a source of HF; a source of H2SiF6, wherein the these compounds may be mixed together in ratios prior to being provided to the digestion unit; a separation unit in communication with the digestion unit for separating the digested carbonaceous material from the acid mixture solution; and a dryer unit in communication with the separation unit for drying the digested carbonaceous material and separating the carbonaceous material based on density.
