摘要： A process for the separation of the aromatic compounds benzene, toluene and xylene from an aromatics-containing reformate gasoline and pyrolysis gasoline or a coke-oven light oil or an aromatics-containing refinery stream, in which the aromatics are separated by an extractive distillation uses a novel solvent combination made up of the compounds n,n′-diformyl piperazine or 2,2′-bis-(cyanoethyl)ether in a combination with n-formyl morpholine as a second solvent for extractive distillation so that the solvent combination obtained shows a higher selectivity with regard to the aromatics to be extracted so that a lower solvent load is required. The aromatics-containing feed mixture is first submitted to a pre-distillation so that the obtained fraction has a narrow boiling point range. This fraction is then submitted to an extractive distillation in a first column, in which an aromatics-lean head product of predominantly paraffinic hydrocarbons is obtained as well as an aromatics-enriched bottom product. The bottom product is passed to a second column in which an aromatics-rich raffinate is obtained by reducing the pressure or increasing the temperature so that the extracting solvent combination obtained as bottom product can be recycled into the process.

摘要： A process for the recovery of a pure aromatics-containing product is disclosed. This product is obtained by extractive distillation of a gasoline rich in aromatics, in which olefins, diolefins and polyolefins are separated, and this extractive distillation is followed by a hydrogenation of the recovered aromatics-rich, olefin-lean product stream, in which the alkylated aromatics, especially toluene and xylene, are dealkylated and the paraffinic dealkylation products further converted into methane so that a significant portion of hydrogen can be saved by carrying out the hydrogenation subsequent to the extractive distillation, as the aromatics mixture is then free of olefins and no hydrogen is required for an olefin hydrogenation, with extractive distillation and recovery of the extracting solvent taking place in one column. An apparatus for carrying out the process described is also disclosed. A column is preferably used for the extractive distillation which allows performing the extractive distillation with a solvent recycling system so that it is not required to provide an additional stripping column for removing the extracting solvent.

摘要： A process for the dehydrogenation of alkanes. In several reactors of the adiabatic, allothermal or isothermal type or combinations thereof a gaseous alkane-containing material stream is passed through a catalyst bed in continuous operating mode. The gas stream produced contains an alkene, hydrogen and a non-converted alkane. In order to achieve a constant product composition, at least one of the process parameters of temperature, pressure or steam/hydrocarbon ratio is recorded in the form of measured values at one or several points of at least one of the reactors, where at least one of the process parameters is selectively controlled and influenced such that the composition of the product gas at the outlet of one reactor remains constant throughout the operating period.
