Abstract

In accordance with particular descriptions provided herein, certain embodiments of the inventive technology may be described as a hydrocarbon viscosity reduction method that comprises the steps of: treating a hydrocarbon having asphaltenes therein to generate a treated hydrocarbon, wherein said hydrocarbon has a first viscosity; contacting said treated hydrocarbon with a sorbent (whether as a result of pouring or other means); and adsorbing at least a portion of said asphaltenes onto said sorbent, thereby removing said at least a portion of said asphaltenes from said hydrocarbon so as to generate a viscosity reduced hydrocarbon having a second viscosity that is lower than said first viscosity.
