Using converted hydrogen and solid carbon from captured methane to power wellbore equipment
Green hydrogen and solid carbon can be produced by reacting captured methane with a catalyst in a reaction chamber. A liquid base fluid can form a continuous phase within the reaction chamber with a plurality of liquid metal carrier droplets dispersed in the base fluid. The catalyst can be nano-sized particles that can coat the surfaces of the carrier droplets. Agitation can be supplied to the reaction chamber to maintain dispersion of the liquid metal carrier droplets and increase contact of the methane and catalyst particles. The reaction temperature can be less than the temperature required for water electrolysis or steam methane reforming processes. The green hydrogen and solid carbon can be used as a power source for wellsite equipment in the form of fuel cells to generate electricity or power or used to charge batteries.

STEAM METHANE REFORMING WITH STEAM REGENERATION
A hydrocarbon is reacted with water in the presence of a catalyst to form hydrogen, carbon monoxide, and carbon dioxide. Hydrogen is selectively allowed to pass through a hydrogen separation membrane to a permeate side of a reactor, while water and carbon-containing compounds remain in a retentate side of the reactor. An outlet stream is flowed from the retentate side to a heat exchanger. The outlet stream is cooled to form a cooled stream. The cooled stream is separated into a liquid phase and a vapor phase. The liquid phase is flowed to the heat exchanger and heated to form steam. The vapor phase is cooled to form condensed water and a first offgas stream. The first offgas stream is cooled to form condensed carbon dioxide and a second offgas stream. The steam and the second offgas stream are recycled to the reactor.
METHOD AND SYSTEM FOR CONVERTING NON-METHANE HYDROCARBONS TO RECOVER HYDROGEN GAS AND/OR METHANE GAS THEREFROM
The disclosure relates to methods, systems, and apparatus arranged and designed for converting non-methane hydrocarbon gases into multiple product gas streams including a predominately hydrogen gas stream and a predominately methane gas steam. Hydrocarbon gas streams are reformed, cracked, or converted into a synthesis gas stream and methane gas stream by receiving a volume of flare gas or other hydrocarbon liquid or gas feed, where the volume of hydrocarbon feed includes a volume of methane and volume of nonmethane hydrocarbons. The hydrogen contained in the syngas may be separated into a pure hydrogen gas stream. A corresponding gas conversion system can include a super heater to provide a hydrocarbon feed/steam mixture, a heavy hydrocarbon reactor for synthesis gas formation, and a hydrogen separator to recover the hydrogen portion of the synthesis gas.
