Embodiment Construction

[0039] Embodiments of the invention are best understood by reference to the drawings, wherein like numerals are used to refer to like parts throughout. It will be readily understood that the components of the present invention, as generally described and illustrated herein in the figures, may be arranged and designed in a variety of different configurations. Therefore, the following as figure 1 and 2 The presented more detailed descriptions of embodiments of the methods and units of the invention are not intended to limit the scope of the invention as claimed, but merely represent current embodiments of the invention.

[0040] The present invention relates to a method of upgrading a hydrocarbon or oil feedstock (such as heavy oil, shale oil, bitumen, etc.) by combining the oil feedstock with an alkali metal and a modified hydrocarbon material or hydrogen combination to cap broken bonds previously attached to heteroatoms and metals. This reaction operates to remove sulfur, ...

Abstract

A process to facilitate gravimetric separation of alkali metal salts, such as alkali metal sulfides and polysulfides, from alkali metal reacted hydrocarbons. The disclosed process is part of a method of upgrading a hydrocarbon feedstock by removing heteroatoms and / or one or more heavy metals from the hydrocarbon feedstock composition. This method reacts the oil feedstock with an alkali metal and an upgradant hydrocarbon. The alkali metal reacts with a portion of the heteroatoms and / or one or more heavy metals to form an inorganic phase containing alkali metal salts and reduced heavy metals, and an upgraded hydrocarbon feedstock. The inorganic phase may be gravimetrically separated from the upgraded hydrocarbon feedstock after mixing at a temperature between about 350 DEC G to 400 DEC G for a time period between about 15 minutes and 2 hours.
