Abstract:
A process for removing color bodies from hydrocarbon-based fuels, particularly gasoline, using an activated carbon is disclosed. Color bodies are removed from the fuel by contacting the fuel with such activated carbon having within this pore structure a fuel decolorizing amount of polymerized phosphoric acid or reduced transition metals. Phosphoric acid may be added to a non-phosphoric acid-activated carbon (such as steam activated coal-based) prior to the subsequent heat treatment or one can take advantage of residual phosphoric acid present in, for example, a phosphoric acid-activated wood-based carbon. Similarly, transition metals such as copper may be added to an activated carbon in a salt form in addition to whatever is already present therein as impurities.
