Process for removing color bodies from hydrocarbon-based fuels using activated carbon

摘要

Disclosed is a process for removing colour bodies from hydrocarbon-based fuel comprising the steps of: a) contacting hydrocarbon-based fuel with a decolorizing carbon having within its pore structure a fuel decolorizing amount of reduced transition metal in the range of from about 0.1% to about 5%; and b) adsorbing at least a portion of colour bodies selected from the group consisting of indanes, naphthalenes, phenanthrenes, pyrene, alkylbenzenes, and mixtures thereof within the hydrocarbon-based fuel onto the decolorizing carbon to produce a decolorized hydrocarbon-based fuel.
