Abstract:
A reactor (12, 128, 198) and method for the conversion of hydrocarbon gases utilizes a reactor (12, 128, 198) having a unique feed assembly (58, 136, 200) with an original vortex disk-like inlet flow spaces (72, 74, 76, 80, 146, 148, 150, 152, 208, 216, 218), a converging-diverging vortex mixing chamber (116), and a cylindrical reactor chamber (40). This design creates a small combustion zone and an inwardly swirling fluid flow pattern of the feed gases that passes through a converging conduit (48) with a constricted neck portion (54). This provides conditions suitable for efficient cracking of hydrocarbons, such as ethane, to form olefins.
Abstract:
The invention concerns a reactor for chemical vapour deposition from first and second precursor gases, the reactor comprising: -a chamber including top and bottom walls and a side wall linking the top and bottom walls, -a support intended for receiving at least one substrate, mounted inside the chamber, and -at least one system for injecting precursor gases, the system comprising an injection head including at least one nozzle for supplying the first precursor gas (41) in a main direction of axis A-A', the at least one nozzle including: a precursor gas supply conduit (321), and an outlet member (322) generating a substantially annular vortex flow (44) around axis A-A'.
Abstract:
A gas distribution apparatus (80), comprising: a distribution manifold (82) in fluid communication with a gas source and a plurality of injection nozzles (60) such injection nozzles (60) comprising a tube (62) with a fluid inlet (64), a fluid outlet (66), an inner diameter and an axial length; wherein the fluid inlet (64) of at least one of the plurality of injection nozzles (60) is disposed within the distribution manifold (82) and a fluid outlet; wherein the inlet (64) of the at least one of the injection nozzles (60) comprises an annular orifice (68) surrounding a flow restriction device (70, 70C, 70F); and wherein the fluid outlet (66) is external to an outer circumference (89) of the distribution manifold (82).
Abstract:
The invention relates to an apparatus (1) for producing pseudoionone and hydroxy pseudoionone. It suggests an apparatus (1) comprising first and second substantially vertically oriented reactor chambers oriented such that components flow through the first and second reactor chambers in different directions, wherein the first reactor chamber (13) is configured to receive a first component feed (C1) containing a first aqueous mixture through an inlet (15), and to produce a second aqueous mixture, and wherein the apparatus (1) comprises a mixing device (17) positioned downstream of the first component feed inlet (15) and configured to add a second component feed (C2) to the first component feed (C1) when the second aqueous mixture has formed, and the second reactor chamber (23) is configured to receive the first and second component feeds unified in the mixing device (17) from the first reactor chamber (13) and to produce a third aqueous mixture from the first and second aqueous mixtures. The invention further suggests a method and a use for producing pseudoionone and hydroxy pseudoionone.
