Abstract: The invention relates to a start-up process for a unit for producing highly thermally-integrated hydrogen by reforming a hydrocarbon feedstock that comprises a stage a wherein a burner whose purpose is to ensure start-up is supplied with a mixture of hydrocarbon feedstock and air, a stage b wherein a water stream is evaporated by indirect heat exchange with at least one of the hot streams of the process, a stage c wherein the hydrocarbon feedstock to be reformed is evaporated and heated and then introduced in gaseous form in a reforming reactor, and a stage d wherein the start-up burner is shut down, and a burner that is in permanent operation is lit.

Abstract: A reactor intended to carry out partial oxidation reactions starting from liquid feedstocks that can go from GPL to gas oil for the purpose of producing synthesis gas is characterized by finely controlled hydrodynamics and a high degree of thermal integration, and comprises an elongated jacket along an axis of any orientation, means (12) for supplying a preheated gas that contains oxygen and optionally water vapor, means (9) for supplying a hydrocarbon feedstock, means (11) for evacuation of a hydrogen-rich effluent, a first internal chamber (5) inside of which is carried out an essentially isothermal partial oxidation reaction that is connected to means (9) for supplying the hydrocarbon feedstock and to means (12) for supplying preheated gas, gas turbulizing means that are suitable for creating a perfect mixing flow, means (8) for linking first chamber (5) to a second chamber (7) with a suitable volume for carrying out a piston flow, linking means (8) that comprise at least one orifice, and second chamber (7

Abstract: Relative and controlled sealing between a pipe (1) and a ceramic tube (7) utilizes a cylindrical chamber (5) that is attached in a sealed manner to the pipe (1), and to one end of the ceramic tube that is placed inside the chamber. At least two sets of sealing fixtures (3, 3?) are placed in an annular space between the ceramic tube and the chamber. A crosspiece (4) is interposed between the two sets sealing of fixtures (3, 3?). A metal mating flange (6) is pressed against a compression ring (4?) to compress the sealing fixtures (3, 3?). Injection of a fluid (8) between the two sets of sealing fixtures (3, 3?) applies a pressure differential that is determined on each of the fixtures.

Abstract: A device has a reaction chamber with at least one feed inlet (5) and at least one evacuation outlet (10). An outside jacket (2a) that is resistant to internal pressure is positioned around the device and contains at least one module (44) through which a reagent and formed products circulate. The module (44) has walls (11) and (12) made of refractory material that are included in a sealed jacket (40). The sealed jacket (40) is connected by a flexible connection to the jacket (2a) and to a heat exchanger that is also linked to the module (44) and to the jacket (2a) by a flexible connection.
