Definitions
- the invention relates to a process for the purification of feed streams containing olefins in polymerization or alkylation processes and to processes for the preparation of alkylbenzenes by catalytic conversion of benzene and olefins.
- Ethylbenzene is mainly obtained by the catalytic alkylation of benzene with ethylene.
- Aluminum chloride is used as the catalyst in the liquid phase and Lewis acids or synthetic zeolites in the gas phase.
- Zeolites are highly active catalysts for both alkylation and transalkylation. Although the zeolite catalysts are less sensitive to water, sulfur and other catalyst poisons, they lose their activity over time and have to be regenerated periodically.
- WO 98/07673 describes the alkylation of benzene with, for example, propylene. The benzene was pretreated by passing it over mordenite.
- the life of zeolite catalysts in the transalkylation of polyalkylbenzenes can be extended by adding gaseous hydrogen.
- No. 5,030,786 proposes to reduce the water content in the aromatics feed stream to below 100 ppm in the alkylation or transalkylation reaction over zeolite catalysts.
- WO 93/00992 finds that the zeolite catalyst should have a minimum water content of more than 3.5 percent by weight, based on the catalyst composition, in the alkylation or transalkylation, especially in the start-up phase.
- ethylene is produced in steam crackers.
- the ethylene content is usually over 99.9 percent by weight. It also contains small amounts of sulfur, oxygen, acetylene, hydrogen, carbon monoxide and carbon dioxide.
- ethylene in large quantities for polymerization to form polyethylene such as HDPE, LDPE and LLDPE used.
- a so-called "polymer grade ethylene" is used in particular for the polymerization.
- the object of the present invention was to find a process for improving the activity of catalysts for olefin polymerization. Furthermore, a method for extending the life and reducing the recycling times of alkylation or transalkylation catalysts in the catalytic alkylation of benzene with olefins, in particular on zeolite catalysts, should be found.
- the process can also be used for feed streams containing olefins in other processes.
- it is particularly suitable for the polymerization and alkylation processes in which catalysts which are sensitive to the smallest amounts of impurities are used.
- Carbon-containing adsorbents such as carbon black, activated carbon or carbon molecular sieves, oxygen-containing compounds such as aluminum oxides, silica gels, natural or synthetic aluminumates, silicates, aluminum silicates or zeolites and molecular sieves are suitable for the adsorption layer.
- oxygen-containing compounds such as aluminum oxides, silica gels, natural or synthetic aluminumates, silicates, aluminum silicates or zeolites and molecular sieves are suitable for the adsorption layer.
- the structure, properties and production of zeolites are described, for example, in Zeolite Molecular Sieves, Donald W. Breck, John Wiley & Sons, 1974; Atlas of Zeolite Structure Types, 3rd Ed. WM Meier and DH Olson, Butterworth-Heinemann, 1992 or Handbook of Molecular Sieves, R. Szostak, Chapman & Hal1, New York, 1992.
- Preferred zeolites are those of the type ZSM-5, ZSM-11, ZSM-12, ZSM-22, ZS -23, ZSM-35, ZSM-48, beta zeolite, zeolite Y, dealuminated zeolite Y, mordenite, zeolite MCM- 22, MCM-41, MCM-49, MCM-56. Also preferred are alumina or activated alumina, especially for alkaline contaminants. Fuller earths are also used occasionally. Because of the surface properties, carbon-containing adsorbents are preferably used for organic and non-polar contaminants. In general, the adsorbents are used in the form of spheres, rods or granules with an external dimension of 1 to 10 mm.
- the process according to the invention can be carried out in sections or continuously in adsorbers with fixed, moving or fluidized beds.
- the adsorption layer is particularly preferably located in a fixed bed reactor. It is expedient to use two or more fixed bed adsorbers which can be operated alternately for the purification of the olefin stream or for the regeneration.
- the size of the adsorber depends on the type and amount of impurities and the desired regeneration cycles.
- the olefin feed stream is passed over the adsorption layer at a temperature in the range from 0 to 300 ° C., preferably 50 to 250 ° C. and a pressure in the range from 1 to 45 bar.
- Ethylene or propylene are preferably used as the olefin.
- Polymer-grade ethylene is particularly preferably used.
- the process according to the invention is preferably used for the pretreatment of ethylene or propylene feed streams in the catalytic alkylation of benzenes, in particular alkylation reactions catalyzed by Lewis acids or zeolites.
- Such methods are e.g. B. in Ulimann, Encycl. of Industrial Chemistry, 5 h Ed. Vol A10, pages 35 to 43. It is particularly preferably used in the zeolite-catalyzed alkylation or transalkylation of benzene and ethylene.
- Such processes and suitable catalysts are described, for example, in US 5,902,917, US 4,891,448, US 5,081,323, US 5,198595, US 5,243,116 or WO 98/07673.
- a zeolite of the same type of the zeolite used for the catalyst or with similar pore diameters and pore size distribution is particularly preferably used for the adsorption layer.
- the benzene or alkyl and polyalkylbenzene feed streams are expediently passed through a corresponding adsorption layer in the alkylation of benzene.
- Example 1 was repeated with the adsorbents shown in the table.
- the desorption was carried out by eluting the adsorbent using 1N H 2 S0.
- the results are summarized in the table.
- the recovery rate is a measure of the adsorption effect.
- Tonsil CO 614 G aluminum silicate from Süd-chemie
