The carbon atom present in the carbon dioxide has an oxidation number of +IV, meaning that it has been oxidized. In every oxidation reaction, another atom must be reduced. For this reason, these reactions also are referred to as oxidation-reduction reactions, or redox reactions. Oxygen, which...
Physical activation has the advantages of a simple production process, less corrosion to equipment, and environmental friendliness. Chemical activation is to mix carbon materials with chemical activators (KOH, H3PO4, NaOH, phytic acid, etc.), and then carbonize at 400–900 °C, which has the...
In the oxidation of hydrocarbons, especially micro-waxes and/or n-paraffins, to functionalised low-mol. hydrocarbons with acid number > 25 mg KOH/g, (1) O2 or air is allowed to act on a stirred melt of paraffin from the degradation of plastics waste, paraffin from petroleum oil and/or ...
