Process for carbonizing cellulosic fibrous substrates |
| abstract |
A process for improving the thermal carbonization of cellulosic substrates comprising treating said substrates prior to carbonization with a catalytic amount of at least one compound selected from esters of phosphoric acid, esters of phosphorothioic acid, phosphoramidic acids, alkylphosphoramidic acids, alkylphosphonic acids, alkylphosphonothionic acids, and phosphonitrile amide derivatives and heating said treated substrates until a carbonized product having a carbon content of at least 50 percent weight carbon is produced. |
