A fuel composition contains a liquid fuel and nano-sized zinc oxide particles. The nano-sized zinc oxide particles can be used to either improve cold start performance of internal combustion engines or lower a flash point temperature of a liquid fuel.
摘要:
Described herein are systems and methods that utilize bicarbonate and acid to form carbon dioxide in a well (e.g., an oil well) to increase pressure in the well to facilitate production of oil and other resources, such as hydrocarbons, from the well. The well can be a closed system that facilitates absorption of the carbon dioxide into the oil resource. After the carbon dioxide is absorbed within the oil, the oil containing the carbon dioxide can be produced by the well. The carbon dioxide can be recycled after the resource is mined from the well to create bicarbonate that subsequently can be used with acid to facilitate the production from the well.
摘要:
A method of recovering petroleum from dormant oil wells or increasing the production of oil wells. An alkali or alkaline earth carbonate is introduced into a water layer associated with a subterranean petroleum reservoir and/or an explosive composition is introduced into an oil layer associated with a subterranean petroleum reservoir. CO2 gas is produced by reacting the alkali or alkaline earth carbonate with an acid and/or by detonating the explosive composition. An explosive composition can be introduced and detonated to achieve sufficient CO2 gas production to increase pressure within the subterranean petroleum reservoir. Petroleum recovery can be further enhanced through the use of recycling.

摘要:
A method of recovering petroleum from dormant oil wells or increasing the production of oil wells. An alkali metal or alkaline earth metal carbonate is introduced into a water layer associated with a subterranean petroleum reservoir and/or an explosive composition is introduced into an oil layer associated with a subterranean petroleum reservoir. CO2 gas is produced by reacting the alkali metal or alkaline earth metal carbonate with an acid and/or by detonating the explosive composition.

An aviation fuel composition contains an aviation fuel and nano-sized zinc particles. Examples of nano-sized zinc particles include nano-sized metallic zinc particles, nano-sized zinc oxide particles, and nano-sized zinc peroxide particles. The aviation fuel composition can be made by combining an aviation fuel and nano-sized zinc particles. The aviation fuel composition can be used to improve combustion in an aircraft engine.
