Title:
ACTIVATED CARBON FOR FUEL PURIFICATION
Document Type and Number:
WIPO Patent Application WO2006104782
Kind Code:
A3
Abstract:
An activated carbon, disclosed as useful in purification and decolorization of hydrocarbon fuel, particularly gasoline, is characterized by inclusion therein of polymerized phosphoric acid. The conversion of phosphoric acid to a polymerized phosphate content occurs during phosphoric acid activation of carbon at activation temperatures in the range of 1150°-1600°F.
