A mobile system and method that reform flare gas, methane, or natural gas, using air without steam, to directly produce methanol, a clean burning gasoline blend, component, and/or substitute are disclosed. The system first reforms the air-methane mixture at ambient atmospheric pressure, then compresses the resulting CO-hydrogen-nitrogen gas mixture to about 600 psi, and feeds it through a methanol reactor which reacts the gas mixture directly into methanol. The nitrogen is returned by the system back to the atmosphere. Methanol is a clean burning gasoline substitute, and can be used to displace significantly costlier and dirtier petroleum-based fuel, while solving a critical problem with flaring. For example, the over 120 billion cubic feet per year that was flared in North Dakota in 2014 could be converted into over 6 million tons of methanol.

A saturator includes: a flow path inside of which a first fluid flows; a first heat exchange unit that causes heat exchange between the first fluid and a second fluid; a second heat exchange unit that causes heat exchange between a third fluid and the first fluid after the first fluid has passed through the first heat exchange unit; a humidifying unit that adds water to the first fluid upstream from the first heat exchange unit and the second heat exchange unit; and a conveyance path that conveys the third fluid after heat exchange from the second heat exchange unit to the upstream side of the first heat exchange unit and causes said third fluid to flow into the flow path as the first fluid.

A Plasma Arc Reformer for creating a useful fuel, such as Methanol, using any of Methane, Municipal Solid Waste, farm or forest waste, coal orchar rock from oil shale production, petrochemical hydrocarbons, (any carbon containing charge), water, and/or Municipal Sewage, as the source material. A High temperature Plasma Arc de-polymerizes the source material into atoms which, upon partial cooling, creates a gas stream rich in CO and H.sub.2 (syngas). Subsequent molecular filter and catalyst stages in the system remove contaminants and produce the output fuel. The system is closed loop with regard to the syngas production in that it recycles the residual unconverted gas and even the exhaust gases if desired. The large amount of heat produced is captured and converted to electric power using a supercritical CO.sub.2 Rankin cycle resulting in potentially high efficiencies.

A method to produce syngas from a feed oil comprising the steps of increasing a pressure of a slurry catalyst; increasing a temperature of the pressurized slurry stream; increasing a pressure of the feed oil; increasing a temperature of the pressurized feed stream; mixing the hot slurry stream and the hot oil stream; increasing a temperature of the mixed stream in a combined heater to produce a hot mixed stream; maintaining upgrading reactions of hydrocarbons in the supercritical reactor to produce a supercritical effluent; reducing a pressure of the supercritical effluent; separating the depressurized effluent in a separator to produce a gas stream; separating the gas stream to produce a light hydrocarbon stream; mixing the light hydrocarbon stream and a catalyst feed; introducing the hot feed to a steam reformer; maintaining water gas shift reactions of the light hydrocarbon gases in the steam reformer to produce a reformer effluent.

In various implementations, feed streams that include methane are reacted to produce synthesis gas. The synthesis gas may be further processed to produce ultrapure, high-pressure hydrogen streams.

A method for producing -rich synthesis gas comprises the following steps: decomposing a hydrocarbon-containing fluid into an H.sub.2/C-aerosol in a first hydrocarbon converter by supplying energy which is at least partly provided in the form of heat; introducing at least a first stream of the H.sub.2/C-aerosol into a first sub-process which comprises the following steps: directing at least a part of the H.sub.2/C-aerosol from the first hydrocarbon converter into a first C-converter; introducing CO.sub.2 into the first C-converter and mixing the CO.sub.2 with the H.sub.2/C-aerosol introduced into the first C-converter; converting the mixture of H.sub.2/C-aerosol and CO.sub.2 into a synthesis gas at a temperature of 800 to 1700 C.; mixing additional H.sub.2 with the synthesis gas for the production of H.sub.2-rich synthesis gas. In a second sub-process running in parallel with the first sub-process, hydrogen H.sub.2 and carbon dioxide CO.sub.2 are produced from a hydrocarbon-containing fluid, wherein at least a portion of the CO.sub.2 produced in the second sub-process is introduced into the first C-converter; and wherein at least a portion of the H.sub.2 produced in the second sub-process is mixed with the synthesis gas from the first C-converter. The CO.sub.2 which is needed for the conversion of C in the first C-converter can thereby be provided independently of an external source, and the entire operational sequence is easily controllable.

A method of generating hydrogen in a subsurface formation, the method comprising injecting oxidizable metal particles into a subsurface formation comprising subsurface water and a geologic trap, wherein the subsurface water has a temperature of from 18 C. to 400 C. and a pressure of from 500 psi to 10,000 psi, the geologic trap comprises one or both of a structural trap or a stratigraphic trap, the geologic trap substantially prevents vertical migration of the subsurface water out of the subsurface formation, and the oxidizable metal particles react with the subsurface water to form hydrogen, metal oxides, metal hydroxides, or combinations thereof.

Hydrogen may be produced from a hydrocarbon through catalytic means. An example method of catalytic hydrogen production includes: introducing a hydrocarbon feedstock to a reactor, wherein the reactor contains therein a catalyst, and wherein the reactor is substantially absent of oxygen and water, and wherein the catalyst includes a sand supported metal catalyst, an aluminum compound supported metal catalyst, or a combination thereof; and reacting the hydrocarbon over the catalyst to produce solid carbon and hydrogen gas.

A method for producing hydrogen (H.sub.2) from methane (CH.sub.4) includes introducing a feed gas stream containing CH.sub.4 into a reactor containing a nickel (Ni) and cobalt (Co)-based titania supported (NCT) catalyst; passing the feed gas stream through the reactor in contact with the NCT catalyst at a temperature of 600 to 1000 C. to convert CH.sub.4 to carbon (C) and H.sub.2, and produce an H.sub.2-containing gas stream leaving the reactor; and separating H.sub.2 from the H.sub.2-containing gas stream. The method has a CH.sub.4 conversion of up to 95% of the initial weight of CH.sub.4 and a H.sub.2 yield of up to 90% based on the CH.sub.4 conversion.
