Abstract
A process for thermally treating a porous cellulosic material to cause considerable decomposition and carbonization, comprising: a. Directly contacting said cellulosic material with an organic or semi-inorganic fluid heated to temperatures between about 25ºC and about 400º c, said fluid being normally liquid at pressures lower than 14.060 kg/cm2 (kilograms per square centimeter) and at the temperature used, almost thermally stable through the temperature range used and almost chemically unreactive towards said cellulosic material and b. Heat the resulting product in an atmosphere inert to a temperature above about 600º c. (Machine-translation by Google Translate, not legally binding)
