Problems solved by technology

For example, in the arid climates of western Colorado and eastern Utah, where parts of the shale oil-green river formation are located, forming hydrogen from water can be expensive
[0012] Thus, while conventional hydrotreating or alkali metal desulfurization processes are known, they are expensive, require significant capital investment to build a functioning plant, and may cause adverse environmental impacts
There is a need in industry for a new process that can be used to remove heteroatoms such as sulfur and nitrogen from oil feedstocks, but is less expensive and more environmentally friendly than conventional treatment methods

Embodiment 1

[0055] The raw oil is derived from (extracted from) the Uintah Basin, Eastern Utah, USA (Uintah Basin, Eastern Utah, USA). This oil feedstock comprises shale oil which contains sulfur and nitrogen. This oil feedstock is centrifuged to remove any solids present. The centrifuged oil feedstock had the following composition:

[0056]

[0057] 179.2 g of centrifuged shale oil was mixed with 6 g of sodium metal in a reaction kettle. 113 psi absolute for shale oil 2 (7.68 atm) methane gas blanket, then heated to 150 °C. Once 150°C is reached, increase the kettle pressure to 528 psi 2 (35.9 atmospheres) absolute pressure for 1 hour. After 1 hour, the heat source was removed from the autoclave and the autoclave was cooled to room temperature. After cooling, the pressure in the autoclave was released.

[0058] The reacted mixture contains a liquid phase and a solid phase. The liquid and solid phases were separated by centrifugation. The oil obtained from the reaction has the...

Embodiment 2

[0065] The raw oil is derived from (extracted from) the Uyingta Basin in eastern Utah, USA. This oil feedstock comprises shale oil which contains sulfur and nitrogen. This oil feedstock is centrifuged to remove any solids present. The centrifuged oil feedstock had the following composition:

[0066]

[0067] 179.2 g of centrifuged shale oil was mixed with 6 g of sodium metal in a reaction kettle. 113 psi absolute for shale oil 2 (7.68 atm) methane gas blanket, then heated to 375 °C. Once 375°C is reached, increase the autoclave pressure to 528 psi 2 (35.9 atmospheres) absolute pressure for 1 hour. After 1 hour, the heat source was removed from the autoclave and the autoclave was cooled to room temperature. After cooling, the pressure in the autoclave was released.

Embodiment 3

[0074]The raw oil is sourced (extracted) from another location in the Uyingta Basin in eastern Utah, USA. This oil feedstock comprises shale oil which contains sulfur and nitrogen. This oil feedstock is centrifuged to remove any solids present. The centrifuged oil feedstock had the following composition:

[0075]

[0076] 179.2 g of centrifuged shale oil was mixed with 6 g of sodium metal in a reaction kettle. 113 psi absolute for shale oil 2 (7.68 atm) methane gas blanket, then heated to 375 °C. Once 375°C is reached, increase the autoclave pressure to 528 psi 2 (35.9 atmospheres) absolute pressure for 1 hour. After 1 hour, the heat source was removed from the autoclave and the autoclave was cooled to room temperature. After cooling, the pressure in the autoclave was released.

Abstract

A method of upgrading an oil feedstock by removing heteroatoms and / or one or more heavy metals from the oil 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 separable from the organic oil feedstock material. The upgradant hydrocarbon bonds to the oil feedstock material and increases the number of carbon atoms in the product. This increase in the number of carbon atoms of the product increases the energy value of the resulting oil feedstock.

Description

[0001] related application [0002] This application claims U.S. Provisional Patent Application Serial No. 61 / 257,369, filed November 2, 2009, entitled "Upgrading of Petroleum Oil Feedstocks Using Alkali Metals and Hydrocarbons" rights and interests. This provisional application is expressly incorporated herein by reference. technical field [0003] This invention relates to a process for the removal of nitrogen, sulfur and heavy metals from shale oil, bitumen or heavy oils containing sulfur, nitrogen and metals so that these materials can be used as hydrocarbon fuels. More specifically, the invention relates to the removal of nitrogen, sulfur and heavy metals from shale oils, bitumen or heavy oils while upgrading these materials to obtain higher hydrogen-to-carbon ratios. Background technique [0004] Demand for energy (and the hydrocarbons that generate it) continues to rise. However, the hydrocarbon feedstocks used to provide this energy often contain sulfur and metals...
