A multi-structured tubular element for producing a reactor for effecting exothermic/endothermic chemical reactions, comprises two or more monolithic thermoconductive bodies, assembled together so that each has a part of the side surface interfaced with the side surface of one or more monolithic thermoconductive bodies adjacent thereto, so as to form as a whole, a honeycomb structure containing a plurality of longitudinal channels extending from one end to the other of said tubular element, suitable for being filled with a granular catalytic solid.

The invention relates to a process for converting hydrocarbons into unsaturated products such as acetylene and/or ethylene. The invention also relates to converting acetylene to olefins such as ethylene and/or propylene, to polymerizing the olefins, and to equipment useful for these processes.

A reactor includes: a main reactor core including main reaction flow channels through which the raw material fluid flows, and main temperature control flow channels through which the heat medium flows along a flow direction of the raw material fluid flowing in the main reaction flow channel; and a pre-reactor core including pre-reaction flow channels of which an outlet side connects with an inlet side of the main reaction flow channels and through which the raw material fluid flows, and pre-temperature control flow channels of which an inlet side connects with an outlet side of the main reaction flow channels and through which the product serving as the heat medium flows along a flow direction of the raw material fluid flowing in the pre-reaction flow channel.

A reactor having a shell comprising: one or more reactor tubes located within the shell, said reactor tube or tubes comprising a plurality of catalyst receptacles containing catalyst; means for providing a heat transfer fluid to the reactor shell such that the heat transfer fluid contacts the tube or tubes; an inlet for providing reactants to the reactor tubes; and an outlet for recovering products from the reactor tubes; wherein the plurality of catalyst receptacles containing catalyst within a tube comprises catalyst receptacles containing catalyst of at least two configurations.

A reactor for gas-phase dehydrogenation of a hydrocarbon-comprising stream with an oxygen-comprising stream over a monolithic heterogeneous catalyst. Catalytically active zone(s) comprising monoliths packed next to one another and/or above one another and a mixing zone having fixed internals upstream of each catalytically active zone. Feed line(s) for the hydrocarbon-comprising gas stream to be dehydrogenated at the lower end of the reactor. Independently regulable feed line(s), which supply distributor(s), for the oxygen-comprising gas stream into each of the mixing zones and discharge line(s) for the reaction gas mixture of the autothermal gas-phase dehydrogenation at the upper end of the reactor. The interior wall of the reactor is provided with insulation. The catalytically active zone(s) is accessible from the outside of the reactor via manhole(s). The catalytically active zone(s), mixing zone, independently regulable feed line(s), and distributor(s), may be designed as one component which can individually be mounted and removed.

An offshore installation or offshore vessel is provided which comprises a reactor system for carrying out steam reforming of a feed gas comprising hydrocarbons.

Fluidic systems, modules, and associated methods are generally described. In some embodiments, a fluidic system comprises a module which is configured such that fluid may flow therethrough with a relatively uniform time-averaged linear flow rate (i.e., the time-averaged flow rate that is perpendicular to the transverse cross-sectional area) and/or time-averaged flux across the transverse cross-sectional area of the module. Advantageously, such modules may behave in a way such that the time-averaged linear flow rate and/or time-averaged flux exhibits minimal or no dependence on the transverse cross-sectional area thereof. This may allow for modules to be scaled-up in a relatively facile manner by merely increasing the transverse cross-sectional area, which may eliminate or substantially reduce the need for other components of the module to be redesigned upon scale-up. In some embodiments, modules may be scaled-up in a manner that requires no or minimal chemical process adjustments.
