Title:
DEHYDRATION METHOD FOR CARBONACEOUS MATERIAL DISPERSION ELEMENT AND METHOD FOR PRODUCING CARBONACEOUS MATERIAL DISPERSION ELEMENT
Document Type and Number:
WIPO Patent Application WO/2022/255474
Kind Code:
A1
Abstract:
Provided is a method for easily and quickly removing moisture from a carbonaceous material dispersion element without impairing the stability of the dispersion element. A method for removing moisture from a carbonaceous material dispersion element formed by dispersing carbonaceous material particles in an organic dispersion medium, the method being characterized by comprising a step for blowing a dry inert gas into the dispersion element held at 20 to 120℃ at a ratio of 6 to 30 L dry inert gas to 100 g dispersion element to bring the dispersion element into contact with the dry inert gas so that moisture in the dispersion element evaporates.
