Claims21
A composition of matter comprising a heavy oil having dispersed therein surface modified solids wherein said surface modified solids comprise solids having adsorbed thereon air oxidized polar hydrocarbons from said heavy oil.
A method of producing a composition of matter said method comprising thermally treating a mixture of heavy oil and solids, wherein said solids have a total surface area of about 1500 square microns or less, in the presence of oxygen for a time and at a temperature sufficient to produce oxidized polars from said heavy oil and to allow said oxidized polars to adsorb onto the surface of said solids wherein said adsorption achieves at least 50% coverage.
