NEW MONOLITHIC POROUS CARBON MATERIAL MODIFIED BY SULFUR, METHOD OF ITS PRODUCTION AND ITS APPLICATION FOR ACCUMULATION AND RECOVERY OF ENERGY

摘要

1. A method of producing a monolithic porous sulfur-modified carbon material, characterized in that it includes at least the following steps: (i) drying a gel containing at least one hydrophilic polymer such as polyhydroxybenzene / formaldehyde, (ii) pyrolysis of the material obtained on step (i), (iii) impregnation of the material from step (ii) with a strong sulfur-containing acid, (iv) heat treatment of the modified sulfur material obtained from the step (iii) at a temperature of from 300 to 500 ° C, preferably from 350 to 500 ° C, even more preferred flax from 300 to 400 ° C, wherein said method comprises a step not gidrirovaniya.2. The method according to claim 1, characterized in that said gel additionally contains at least one latex. The method according to claim 2, characterized in that said latex is a nitrogen-containing latex, preferably selected from nitrile rubbers. The method according to one of claims 1 to 3, characterized in that step (i) of the drying is carried out either by replacing the solvents and then drying in a supercritical CO environment, or by convective drying in a gas stream or in an artificial climate chamber with controlled relative humidity, or by lyophilization. 5. The method according to one of claims 1 to 3, characterized in that step (ii) of pyrolysis is carried out in a nitrogen atmosphere according to the following protocol: - a slow temperature increase at a speed of from 1 to 5 ° C / min to a temperature of 400-500 ° C, this temperature can be maintained for a period of about one hour, then a more rapid increase in temperature at a rate of 5 to 20 ° C / min to a temperature of 800-1500 ° C, and this temperature can be maintained for a period of about two hours.
