Abstract:
A catalytic reactor comprises a particle separator which extracts particles from the fluid flow stream above the reactor internals by means which makes the fluid flow stream perform a radial outwards and upwards S-curve flow path, which enables the particles to be extracted and settle in a collection section with low flow activity and turbulence.
Abstract:
The present invention discloses a method and an apparatus for mixing and atomizing a hydrocarbon stream using a diluent/dispersion stream. In one embodiment, the apparatus comprises: an inner conduit and an outer conduit concentric to each other to define an annular space, said outer conduit having an inlet for receiving the hydrocarbon stream and an outlet for dispensing a mixture comprising the hydrocarbon and the dispersion/diluent streams; a diluent/dispersion steam distributor being in connection with the inner conduit and defining a central orifice and a first set of orifices, said first set of orifices adapted to direct a first portion of the dispersion/diluent stream into the annular space and said central orifice adapted to direct a second portion of the diluent/dispersion stream into the inner conduit; atleast one contraction member and expansion member, said contraction member located downstream of the first set of orifices and said expansion member located downstream said expansion member; the inner conduit located downstream of said expansion member comprises a second set of orifices, said second set of orifices disposed on a periphery of the inner conduit and adapted to dispense a second portion of the dispersion/diluent stream into the annular space.
Abstract:
A liquid fuel catalytic partial oxidation (CPOX) reformer can include a plurality or an array of spaced-apart CPOX reactor units, each reactor unit including an elongate tube having a gas-permeable wall with internal and external surfaces, the wall enclosing an open gaseous flow passageway with at least a portion of the wall having CPOX catalyst disposed therein and/or comprising its structure. The catalyst-containing wall structure and open gaseous flow passageway enclosed thereby define a gaseous phase CPOX reaction zone, the catalyst-containing wall section being gas-permeable to allow gaseous CPOX reaction mixture to diffuse therein and hydrogen rich product reformate to diffuse therefrom. At least the exterior surface of the CPOX reaction zone can include a hydrogen barrier. The liquid fuel CPOX reformer can include a vaporizer, one or more igniters, and a source of liquid reformable fuel.

The hydrogen-rich reformate can be converted to electricity within a fuel cell unit integrated with the liquid fuel CPOX reactor unit.
Abstract:
The present invention is capable of precisely controlling a supply ratio of liquid and continuously supplying liquid at a constant rate by using partition plates for controlling the amount of liquid distribution.
Abstract:
Gegenstand der Erfindung ist ein Verfahren zur endothermen Gasphasenreaktion in einem Reaktor, bei dem Eduktgase über eine Gaseinlassvorrichtung in den Reaktor eingebracht und mittels einer Gasverteilungsvorrichtung gleichmäßig in eine Heizzone verteilt werden, wobei in der Heizzone die Eduktgase mittels Heizelementen auf eine mittlere Temperatur von 500-1500°C aufgeheizt und anschließend in eine Reaktionszone geführt werden, wobei die Eduktgase in der Reaktionszone zu einem Produktgas reagieren, das über eine Gasauslassvorrichtung aus dem Reaktor geführt wird. Weitere Gegenstände der Erfindung beziehen sich auf ein Verfahren zur endothermen Gasphasenreaktion in einem Reaktor, wobei das Aufheizen der Heizelemente durch Temperaturmessungen in der Reaktionszone gesteuert wird, wobei zu diesem Zweck wenigstens zwei Temperaturfühler in der Reaktionszone vorhanden sind, sowie einen Reaktor zur Durchführung des Verfahrens.
