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.

A method for thermal cracking of a hydrocarbon to produce hydrogen gas and carbon comprises heating a molten medium to an operating temperature sufficient to thermally crack the hydrocarbon. The operating temperature may, for example be in the range of 600° C. to 1100° C. The method mixes the hydrocarbon into the heated molten medium and pumping the mixed molten medium and hydrocarbon through a reactor. In the reactor, the hydrocarbon undergoes a thermal cracking reaction which forms hydrogen gas and carbon black. The method separates the carbon and hydrogen gas from the molten medium that has passed through the reactor. In some embodiments, the flow of the molten medium in the reactor is a turbulent flow.

A device for the descending flow of a hydrocarbon-containing liquid containing solid particles at the bottom of an item of equipment (1) and a process for the conversion of hydrocarbon-containing feedstocks implementing said device.

The system includes a reactor vessel having a reactor space bound by a reactor wall. The reactor vessel is arranged for holding a mixture of a catalyst and formic acid in the reactor space.

The invention relates to the chemical industry and can be used for processing methane and other volatile, liquid, solid fusible hydrocarbons when producing hydrogen, soot, and other flammable gases. The invention relates to a method for the pyrolytic decomposition of hydrocarbons, in which a pyrolysis reactor arranged in a space bounded by a lining is heated by flue gases generated by combusting a hydrogen-enriched mixture of air and gaseous hydrocarbons, while ensuring a maximum decrease in CO.sub.2 emissions into the atmosphere. The invention also relates to a unit for the pyrolytic decomposition of hydrocarbons. The technical result is a high degree of separation of hydrogen and carbon by fast high-temperature pyrolysis at atmospheric pressure without oxygen supply and without CO.sub.2 production.

An integrated catalytic process for upgrading a feed oil comprises the steps of introducing a catalyst precursor solution to a supercritical water (SCW) process unit, where the catalyst precursor solution comprises a catalyst precursor dissolved in liquid water; introducing a feed water to the SCW process unit; introducing the feed oil to the SCW process unit; treating the catalyst precursor solution, the feed water, and the feed oil in the SCW process unit to produce a SCW effluent, where the catalyst precursor is converted to catalyst particles; separating the SCW effluent in a separator unit to produce a SCW distillate product, a SCW residue product; introducing the SCW residue product to a slurry hydroprocessing unit, where the SCW residue product comprises the catalyst particles; treating the SCW residue product and the hydrogen gas in the slurry hydroprocessing unit to produce a product gas stream and an upgraded oil product.

A method and apparatus for controlling the atmosphere of a multizone calcination (firing) furnace for production of high-quality nickel-rich cathode material for lithium-ion and solid-state batteries. A high-quality oxygen-rich atmosphere is maintained to ensure the quality of the cathode material. An atmosphere control system continuously measures and analyzes the composition of the calcination furnace atmosphere in different zones and adjusts the flowrate of oxygen-rich atmosphere into the furnace to optimize the calcination process.

Two inline tower gas wet scrubbers having a moving bed of solids for scrubbing exhaust gas

Two inline tower gas wet scrubbers wherein each scrubber has a moving bed of solids 0010 that is conveyed from the top to the bottom of the towers via a plurality of perforated moving floors 003 arranged one above the other. Wherein the moving floors are mounted on plenums 004 that extend from the internal walls of the towers. A liquid 008 is sprayed from the top of each tower, wherein the liquid washes the exhaust gas, capturing particle matter and absorbing acidic gases and heat. As the liquid falls under gravity, the liquid is filtered through the solids. Exhaust gas e.g. containing CO.sub.2 enters the first scrubber 001 above the bottom plenum and travels upwards over the moving bed towards the outlet at the top of the scrubber, whilst being washed by the falling liquid. The warm carbonated solids and liquid that exit the first reactor are fed into the top of the second reactor 002, whilst the gas exiting the first reactor enters the second reactor via the plenums/ducts that support the moving floors thereby distributing the gas throughout the reactor.

The present invention relates to a process for the polymerization of olefin monomers in the presence of a catalyst system, using a tubular pre-polymerization reactor, wherein the tubular pre-polymerization reactor has a length L and the flow of a catalyst system is introduced in the tubular pre-polymerization reactor in the middle (30-70% of L) or the end (70-95% of L) of the tubular pre-polymerization reactor.
