The present invention relates to a process for preparing cyclohexane by isomerizing a hydrocarbon mixture (HM) comprising methylcyclopentane (MCP) in the presence of a catalyst. The catalyst is preferably an acidic ionic liquid. The starting material used is a stream (S) which originates from a steamcracking process. The hydrocarbon mixture (HM) obtained from this stream (S) in an apparatus for aromatics removal has a reduced aromatics content compared to stream (S), and (HM) may optionally also be (virtually) free of aromatics. Depending on the type and amount of the aromatics remaining in the hydrocarbon mixture (HM), especially in the case that benzene is present, the isomerization may additionally be preceded by performance of a hydrogenation of (HM). In addition, depending on the presence of other components of (HM), further purification steps may optionally be performed prior to or after the isomerization or hydrogenation. High-purity (on-spec) cyclohexane is preferably isolated from the hydrocarbon mixture (HM) obtained in the isomerization, the specifications being, for example, those applicable to the use of the cyclohexane for the preparation, known to those skilled in the art, of caprolactam.

Process for preparing cyclohexane with starting materials originating from a steamcracking process

The invention relates to a process for the autothermal gas-phase dehydrogenation of a hydrocarbon-comprising gas stream by means of an oxygen-comprising gas stream over a heterogeneous catalyst configured as a monolith to give a reaction gas mixture and regeneration of the catalyst in a reactor in the form of a cylinder or prism, wherein the reactor is operated alternately in the production mode of the autothermal gas-phase dehydrogenation and in the regeneration mode.

Continuous process for carrying out autothermal gas-phase dehydrogenations

A reactor includes an essentially horizontal cylinder for carrying out an autothermal gas-phase dehydrogenation of a hydrocarbon-comprising gas stream using an oxygen-comprising gas stream to give a reaction gas mixture over a heterogeneous catalyst configured as monolith. The interior of the reactor is divided by a detachable, cylindrical or prismatic housing, which is arranged in the longitudinal direction of the reactor and is gastight in the circumferential direction, into an inner region having one or more catalytically active zones, each having a packing composed of monoliths stacked on top of one another, next to one another and behind one another and before each catalytically active zone in each case a mixing zone having solid internals are provided and into an outer region, which is supplied with an inert gas, arranged coaxially to the inner region. A heat exchanger is connected to the housing at one end of the reactor.

The present invention relates to a process for nonoxidatively dehydroaromatizing a reactant stream comprising C-C-aliphatics by converting the reactant stream in the presence of a catalyst in a reaction zoneto a product stream P comprising aromatic hydrocarbons, and regenerating the catalyst whose activity has been reduced by deposited coke with a hydrogen-comprising mixture H in a reaction zone, wherein at least a portion of the deposited coke is converted to methane and at least a portion of the methane formed is fed to reaction zone

The invention relates to a process for the electrochemical separation of hydrogen from a hydrogen-comprising reaction mixture R by means of a gastight membrane-electrode assembly comprising at least one selectively proton-conducting membrane and at least one electrode catalyst on each side of the membrane, where at least part of the hydrogen present in the reaction mixture R is oxidized to protons over the anode catalyst on the retentate side of the membrane and the protons are, after passing through the membrane to the permeate side,

Method for electrochemically removing hydrogen from a reaction mixture

A reactor in the form of an essentially horizontal cylinder for carrying out an autothermal gas-phase dehydrogenation of a hydrocarbon-comprising gas stream by means of an oxygen-comprising gas stream to give a reaction gas mixture over a heterogeneous catalyst configured as monolith is disclosed herein. The interior of the reactor is divided by a detachable, cylindrical or prismatic housing which is arranged in the longitudinal direction of the reactor, gastight in the circumferential direction and open at two end faces of the housing into an inner region, having one or more catalytically active zones. In each case, a packing composed of monoliths may be stacked on top of one another, next to one another, and above one another and before each catalytically active zone. Also in each case, a mixing zone having solid internals and an outer region arranged coaxially to the inner region are provided.
