Definitions
- the invention relates to a process for the selective hydrogenation of dienes, in particular of dienes in reformate streams (feed streams) over a nickel-containing precipitation catalyst. Furthermore, the invention relates to a method for producing high-purity aromatics or aromatic mixtures.
- the reformate produced by catalytic reforming of naphtha represents a very important source of aromatics for the production of pure aromatics.
- Essential components of the reformate are aromatic compounds such as benzene, toluene, xylene and ethylbenzene.
- the boiling range of the hydrocarbon mixture is between 60 and 180 ° C.
- the untreated reformate streams contain constituents such as olefins and diolefins.
- a series of distillation, extraction and extractive distillation stages have hitherto been used for further processing to the pure aromatics.
- FR-A 2 720 754 discloses that in the case of pyrolysis gasoline, dienes can be hydrogenated selectively over a palladium impregnation catalyst at about 150 ° C. and about 15 bar.
- the object of the present invention is to provide a method for the selective hydrogenation of dienes, in which
- This object is achieved by a process for the selective hydrogenation of dienes in feed streams containing dienes, which is characterized in that such feed stream containing dienes is carried out over a nickel-containing precipitation catalyst at a temperature between 40 and 100 ° C. and a pressure between 3 and 20 bar and a WHSV between 1 and 10 kg / (lxh) is hydrogenated in the presence of free hydrogen.
- nickel-containing precipitation catalysts as are known per se from EP-A 0 672 452 permit very effective selective hydrogenation of dienes, the hydrogenation with this catalyst under high reformate loading and under low pressure and low temperature conditions is carried out. It is possible with the process according to the invention that, when operating under low pressure and temperature conditions and high reformate throughput, the hydrogen is fed into the hydrogenation reactor in a quantity-controlled manner with respect to the hydrogenating dienes.
- nickel falling catalysts used according to the invention are described in EP-A 0 672 452. These are catalysts which essentially contain 65 to 80% nickel, calculated as nickel oxide, 10 to 25% silicon, calculated as silicon dioxide, 2 to 10% zirconium, calculated as zirconium oxide and 0 to 10% aluminum, calculated as aluminum oxide, contain with the proviso that the sum of the content of silicon dioxide and aluminum oxide is at least 15% (percentages in% by weight, based on the total mass of the catalyst).
- the catalysts used according to the invention preferably contain 70 to 78% nickel, 10 to 20% silicon, 3 to 7% zirconium and 2 to 10% aluminum. Catalysts which contain only nickel as the catalytically active metal are preferably used. In particular, such catalysts that are free of palladium can be used.
- the catalysts can contain up to 10% of promoters. These are compounds such as CuO, TiO 2 , MgO, CaO, ZnO and B 2 O 3 . However, catalysts which do not contain any promoters are preferred.
- aqueous acid solutions of nickel, zirconium and optionally aluminum salts are used.
- Suitable salts are organic and inorganic salts such as acetates, sulfates, carbonates, but preferably nitrates of the metals mentioned.
- the total content of metal salts is generally 30 to 40% by weight. Since the later precipitation of the metals from the solution is practically quantitative, the concentration of the individual components in the solution depends only on the content of this component in the catalyst to be produced.
- the aqueous solution is adjusted to a pH below 2 by adding a mineral acid, preferably nitric acid.
- This solution is introduced, advantageously with stirring, into an aqueous basic solution which contains silicon compounds and, if desired, aluminum compounds.
- This solution contains, for example, alkali metal hydroxide or preferably soda, generally in amounts of 15 to 40% by weight, based on the solution.
- the pH is generally above U.
- SiO 2 can also be used as the silicon compound.
- the silicon content of the solution is expediently 0.5 to 4% by weight.
- the solution can, if desired Contain aluminum compounds in the form of oxidic solids, although it is preferred to add aluminum salts only to the acidic solution.
- the acidic addition to the basic solution is generally carried out at 30 to 100 ° C., preferably at 60 to 80 ° C. It is usually carried out over a period of 0.5 to 4 hours.
- catalysts which contain promoters are desired, it is expedient to add soluble metal salts to one of the solutions described as precursors for the promoters, to co-precipitate these metals and to process them further with the precipitation product thus obtained.
- the promoters can also be added to the precipitation solution as solids.
- the precipitated product is isolated, for example by filtration. As a rule, this is followed by a washing step, in which case alkali metal ions and nitrate ions which are entrained during the precipitation are washed out.
- the solid obtained in this way is then dried, for which a drying cabinet or a spray dryer, for example, can be used, depending on the amount of the dry material. In general, the drying temperature is 100 to 200 ° C.
- the above-mentioned promo- gates are added.
- the dried product is then preferably calcined, which generally takes place at temperatures of 300 to 700 ° C., preferably 320 to 450 ° C., over a period of 0.5 to 8 hours.
- the calcined solid is shaped into shaped bodies, for example by extrusion into strands or by tableting.
- known peptizing agents such as nitric acid or formic acid are added to the calcined solid in amounts of generally 0.1 to 10% by weight, based on the solid to be deformed.
- Graphite e.g. Graphite can be used.
- the shaped bodies obtained in this way are generally calcined at temperatures of 300 to 700 ° C., preferably 350 to 500 ° C., over a period of 1 to 8 hours.
- the feed streams preferably used in the process according to the invention contain from about 15 to about 90% by weight of aromatics and up to about 5000 ppm by weight of dienes.
- the most preferred feed streams are reformate streams.
- the hydrogen is fed into the hydrogenation stage in such a quantity-controlled manner that about as much hydrogen is added as is necessary for the hydrogenation of the dienes.
- the control is preferably carried out in such a way that 1 to 1.3, preferably 1 to 1.2, particularly about 1.2 moles of hydrogen are fed into the feed stream per mole of diene structure.
- a catalyst is preferably used in the process which contains 65 to 80% by weight of nickel, 10 to 25% by weight of silicon, 2 to 10% by weight of zirconium, 0 to 10% by weight of aluminum - all components as Oxides calculated and percentages in wt .-%, based on the total mass of the catalyst - with the proviso that the sum of the content of silicon dioxide and aluminum oxide is at least 15%.
- hydrogenated product is separated into an aromatic hydrocarbon mixture and a non-aromatic hydrocarbon mixture in an extractive distillation stage.
- the aromatics content of the mixture to be hydrogenated is increased prior to the selective hydrogenation by one or more upstream distillation, extraction and / or extractive distillation stages.
- the nickel-containing precipitation catalysts described also show a high selectivity in the hydrogenation of dienes in hydrocarbon mixtures rich in aromatics, if the process is designed in such a way that the catalyst has a high feed current, in particular reformate stream, at low pressure and temperature stages. Throughput is loaded, and the hydrogen is fed into the reactor in a quantity-controlled manner in relation to the dienes to be hydrogenated.
- the use of the hydrogenation stage according to the invention is particularly suitable in combination with a downstream extractive distillation of the hydrogenated product for working up and obtaining the valuable aromatics. It is already known that aromatic hydrocarbon mixtures from mixtures of aromatic and non-aromatic hydrocarbons can be obtained selectively by extractive distillation, the organic solvent used consisting of a high-boiling polar liquid (Ullmann's Encyclopedia of Industrial Chemistry, 5th ed. , Vol. A3, page 490, Verlag Chemie). DE-A 20 40 025 discloses that N-substituted morpholines are particularly suitable as such a selective solvent. The preferred solvent for the extractive distillation stage is NFM (N-formylmorpholine).
- the compounds obtained in the selective hydrogenation of the reformate stream can be separated very easily from the aromatic hydrocarbon mixture during the extractive distillation stage. If the hydrogenation conditions are too drastic (for example end-of-run conditions) or the catalyst is too active, aromatics may possibly be hydrogenated. The naphthenes which occur are likewise removed from the aromatic mixture during the extractive distillation stage, so that a high degree of purity of the substance is ensured without additional post-treatment with alumina.
- the practical example of the method according to the invention is demonstrated using the example below.
- a benzene-rich reformate cut was used as the starting hydrocarbon mixture.
- the purity compared to existing diene compounds was checked using the wash color test according to ASTM D-848.
- the experimental reactor was operated in the Riesel mode under the following conditions:
