Systems and methods for molten media pyrolysis for the conversion of methane into hydrogen and carbon-containing particles are disclosed. The systems and methods include the introduction of seed particles into the molten media to facilitate the growth of larger, more manageable carbon-containing particles. Additionally or alternatively, the systems and methods can include increasing the residence time of carbon-containing particles within the molten media to facilitate the growth of larger carbon-containing particles.

The invention relates to a method for producing an oil rich fraction (OF) from primary feedstock (FS) that comprises water, first salt, second salt, and biomass. The feedstock (FS) is provided to a first reaction zone (Z1) of a conversion reactor (100), where it is allowed to react at a temperature of at least 350° C. in a pressure of at least 160 bar to form converted primary feedstock. The method comprises separating from the converted primary feedstock a first salt rich fraction (SF1), a second salt rich fraction (SF2), and an oil rich fraction (OF). The method comprises withdrawing the oil rich fraction (OF) from the first reaction zone (Z1) and withdrawing the first salt rich fraction (SF1) and the second salt rich fraction (SF2) from the conversion reactor (100). In the method the first salt rich fraction (SF1) comprises at least some of the first salt dissolved in the water, the second salt rich fraction (SF2) comprises at least some of the second salt in solid form, and at least one of the first salt and the second salt is a salt capable of catalysing the reaction of the biomass of the primary feedstock (FS) with the water of the primary feedstock (FS) to produce the oil rich fraction (OF). A device for the same.

The present disclosure provides Lazarev reactor that sustains reaction of two dimensional polymerization on the interface of two immiscible solutions A and B carrying components of reaction to the interface where reaction takes place and produces film of two dimensional polymer layers that are pulled out of reactor and rolled up on roll after drying excess of solvent out.

A process and apparatus for the continuous conversion of isotropic carbonaceous materials into anisotropic mesophase pitch is disclosed. The invention disclosed herein addresses the need for lower production costs compared with traditional batch mesophase conversion of isotropic pitch. A unique thermal processing and in-process separation of reacted mesophase from the continuous matrix of fresh or partially reacted isotropic pitch is provided. Potential uses are for further continuous processing into carbon fibers or carbon form densification.

Fouling of an MMA process is reduced by strategically removing an aqueous slip stream.

The present disclosure relates to a process for the preparation of polyethylene by polymerizing in a slurry ethylene and optionally one or more C.sub.3 to C.sub.10 alpha-olefins. In some embodiments, the polymerization is carried out in a cylindrical polymerization reactor equipped with an agitator for mixing the contents of the reactor and inducing a flow of the slurry, the ethylene is fed into the reactor by an ethylene injection system comprising one or more injection nozzles which project through the bottom reactor head or through the reactor wall and extend from 0.02-0.5 times the inner diameter D into the reactor, and the ethylene exits the injection nozzle with an exit velocity from 10-200 m/s.

A facility for producing a composite material that includes carbon nanotubes. The facility includes a reaction chamber with an injection device for injecting an active gas mixture (for the growth of the carbon nanotubes) into the interior volume thereof. A transport device is to transport a substrate into the reaction chamber to form the composite material. The injection device may transport the active gas mixture in a first direction into the interior volume. A circulation device is to circulate the active gas mixture, and may transport the active gas mixture into the interior volume in a second direction that is different from the first direction. The circulation device may adopt a first configuration of injection of the active gas mixture into the interior volume of the chamber, and a second configuration of extraction of the active gas mixture from the interior volume.

Processes and systems for the recovery of solvents from a feedstock are provided, as well as processes and systems for the recovery of target botanical compounds. The processes and systems include a heated mixing device, in which a feedstock can be simultaneously mixed and heated to vaporize and release a solvent or botanical compound from the feedstock. The vaporized solvent or botanical compound can be condensed and collected as recovered solvent or a recovered botanical compound,

An ammonia-based multi-zone double-loop process for ultra-low emission of multi-pollutant. From an absorption tower inlet, the flue gas successively passes through cooling concentration crystallization, sulfur oxide absorption, water washing and purifying and dust and mist removing zones, which are separated by gas permeable liquid collecting plates, forming clean flue gas and discharged from an outlet. The cooling concentration crystallization zone, the sulfur oxide absorption zone, and the water washing and purifying zone are respectively provided with a plurality of sprayers, and respectively use a concentration liquid, an absorption liquid, and a water washing liquid as spraying liquids. The absorption, concentration and water washing liquids, after converging respectively, into absorption, concentration crystallization and water washing circulation tanks, the absorption, concentration and water washing liquids, respectively, are sprayed in a circulating manner through absorption, concentration and water washing pumps.
