Abstract:
A molten metal reactor for converting a carbon material and steam into a gas comprising hydrogen, carbon monoxide, and carbon dioxide is disclosed. The reactor includes an interior crucible having a portion contained within an exterior crucible. The interior crucible includes an inlet and an outlet; the outlet leads to the exterior crucible and may comprise a diffuser. The exterior crucible may contain a molten alkaline metal compound. Contained between the exterior crucible and the interior crucible is at least one baffle.
Abstract:
A molten salt treatment system and process can include one or more tubular conduits flowably connected to a molten salt reactor, the tubular conduit containing concentrically within it a pipe or a shaft separated by an annular space therebetween, and one or more gas sources connected to feed gas into the annular space. The system may include a scrubbing device flowably connected to a molten salt reactor off-gas outlet to receive an off-gas, a first heating device configured to heat the effluent from the scrubbing device, and a filtering device flowably connected to receive the effluent from the heating device. An overflow conduit may be flowably connected to a molten salt reactor overflow outlet to receive molten salt therefrom and discharge the molten salt to a salt recovery vessel, and a blower or other gas mover may be connected to the molten salt reactor and the recovery vessel to prevent backflow of cold gases through the overflow outlet to the molten salt reactor.
Abstract:
A resin production apparatus of the present invention includes: a reactor vessel having a vessel main body which polymerizes an ingredient to produce a thermoplastic synthetic resin which solidifies at room temperature and storing the synthetic resin in the molten state, an output mechanism disposed at a bottom part of the vessel main body, which outputs the synthetic resin in the molten state, and a temperature adjustment mechanism which adjusts temperatures of the vessel main body and the output mechanism so as to maintain the molten state of the synthetic resin; a cooling mechanism arranged below the reactor vessel, which continuously cools and solidifies the synthetic resin output from the output mechanism; and a crushing mechanism which crushes the synthetic resin fed out from the cooling mechanism.
Abstract:
The present invention describes a reactor (1) for continuously preparing hydrogen sulfide H2S from hydrogen and sulfur, comprising a distributor device (15) for distributing gaseous hydrogen in a sulfur melt (9) present at least in a lower part of the reactor. The distributor device (15) is arranged in the sulfur melt (9) and comprises a distributor plate (16) which is arranged in the reactor (1) and has an edge (17) extending downward and, if appropriate, has passage orifices (19). The hydrogen from a hydrogen bubble which forms below the distributor plate (16) is (for example through the passage orifices (19)) distributed in the sulfur melt (9) via the distributor plate (16).
Abstract:
The invention relates to a reaction vessel in which hydrogen sulphide is prepared from sulphur and hydrogen, wherein the reaction vessel consists partly or entirely of a material which is resistant to the reaction mixture, its compounds or elements and retains its resistance even at high temperatures.

Abstract:
A particle generator is able to generate pure particles for solid or liquid materials with melting points over several hundred degrees Celsius. The material is heated to generate the vapor in a small chamber. Heated nitrogen or some inert gas is used as the carry gas to bring the mixture into a dilution system. As the super saturation ratio of the material is large enough and over a critical value, particles are formed in the dilution system by homogenous nucleation, and grown in the same dilution system as well. The different size distributions and concentrations of the particles can be obtained by varying dilution parameters, such as residence time and dilution ratio.
Abstract:
Solar Grade Silicon is produced by decomposition of a silicon precursor, preferably trichlorosilane, in the presence of an excess of hydrogen gas, where the reactant are introduced in a reaction chamber whose lower portion is held at a temperature above the melting point of silicon and whose upper portion is held at ambient temperatures. The method is distinguished by the introduction of trichlorosilane through a feed pipe which is arranged coaxially inside an outer pipe for introducing hydrogen gas that functions as a cooling medium for the introduced fluid trichlorosilane. The silicon formed is collected in the lower portion of the reactor and removed through an outlet. Excess hydrogen and hydrogen chloride is withdrawn through an outlet and can, after purification, be used as reactants in the essentially closed system for the production of pure silicon from low grade silicon. Silicon particles in the off gases can be separated, melted and recycled using a particle recapture tower.
Abstract:
A process for the production of melamine by pyrolysis of urea in a high-pressure reactor having a vertical central pipe is provided. The melamine flows upwards into the reactor from below, mixes in the lower part of the reactor with a urea melt, and optionally NH3, introduced into the reactor from below, and emerges from the central pipe in the upper part of the central pipe. Part of the melamine formed flows downward in the annular space between the central pipe and reactor wall, and the remainder is expelled for further work-up. The off-gases are removed at the top of the reactor. A reactor for carrying out the process is also provided.
Abstract:
A molten metal reactor (10) quickly entrains a feed material in the molten reactant metal (16) and provides the necessary contact between the molten reactant metal and the feed material to effect the desired chemical reduction of the feed material. The reactor (10) includes a unique feed structure (24) adapted to quickly entrain the feed material into the molten reactant metal (16) and then transfer the molten reactant metal, feed material, and initial reaction products into a treatment chamber (12). A majority of the desired reactions occur in the treatment chamber (12). Reaction products and unspent reactant metal are directed from the treatment chamber (12) to an output chamber (14) where reaction products are removed from the reactor. Unspent reactant metal (16) is then transferred to a heating chamber (15) where it is reheated for recycling through the system.
