1608 results about "Hydrogen compounds" patented technology

Hydrogen combined with oxygen, is water (H2O). Hydrogen combined with carbon, forms different compounds such as methane (CH4), coal, and petroleum. Hydrogen is also found in all growing things—biomass. It is also an abundant element in the earth's crust.

In situ method and system for extraction of oil from shale

A system and process is disclosed for retorting oil shale and extracting shale oil and other hydrocarbons therefrom, in which a cased heat delivery well is drilled generally vertically through an overburden and then through a body of oil shale to be retorted to the bottom thereof, generally horizontally under the body of oil shale to be retorted, and then back to the earth surface. Heat energy is transmitted conductively to the body of oil shale to be retorted from a closed loop heat delivery module in the well, the module comprising a fluid transmission pipe containing a heating fluid heated to at least a retorting temperature. Heat energy is also transmitted to the body of oil shale to be retorted above the fluid transmission pipe by vapor conduits that conduct retort vapors upward through the body of oil shale to be retorted; the ascending retort vapors condense and reflux, delivering their latent heat of vaporization to the body of oil shale to be retorted, and the condensed retort liquids descend. If not recycled, the retort liquids are collected in a sump at the bottom of a production well and are transmitted to the surface for processing. The vapor conduits communicate at upper ends thereof with the production well, so that vapors that do not reflux are collected in the production well and are transmitted to the surface for processing.

Systems, methods, and compositions for production of synthetic hydrocarbon compounds

A process and system for producing hydrocarbon compounds or fuels that recycle products of hydrocarbon compound combustion—carbon dioxide or carbon monoxide, or both, and water. The energy for recycling is electricity derived from preferably not fossil based fuels, like from nuclear fuels or from renewable energy. The process comprises electrolysing water, and then using hydrogen to reduce externally supplied carbon dioxide to carbon monoxide, then using so produced carbon monoxide together with any externally supplied carbon monoxide and hydrogen in Fischer-Tropsch reactors, with upstream upgrading to desired specification fuels—for example, gasoline, jet fuel, kerosene, diesel fuel, and others. Energy released in some of these processes is used by other processes. Using adiabatic temperature changes and isothermal pressure changes for gas processing and separation, large amounts of required energy are internally recycled using electric and heat distribution lines. Phase conversion of working fluid is used in heat distribution lines for increased energy efficiency. The resulting use of electric energy is less than 1.4 times the amount of the high heating value of combustion of so produced hydrocarbon compounds when carbon dioxide is converted to carbon monoxide in the invention, and less than 0.84 when carbon monoxide is the source.
