    Abstract: Process for oligomerizing an alkene stream over a solid catalyst comprising sulfur and nickel, in which the oligomerization is carried out in two or more successive catalyst zones and the molar ratio of sulfur to nickel in the first catalyst zone is less than 0.5 and that in the last catalyst zone is 0.5 or more and, in the case of further catalyst zones between the first and last catalyst zones, the molar ratio of sulfur to nickel in each catalyst zone is not less than that in the immediately preceding catalyst zone, based on the main flow direction of the feed stream.

    Abstract: La invencion se refiere a un metodo para producir eteres de poliolalquilo al hacer reaccionar al menos tres compuestos teniendo funciones de hidroxi con olefinas en presencia de catalizadores acidos a temperaturas de entre 20 - 250 degree C y presiones de entre 0.5 - 10 bar. Las olefinas corresponden a la formula general (I), en donde R1 representa hidrogeno y R2 es radicales de carbono lineales o ramificados teniendo 7 - 28 atomos de carbono, o R1 y R2 respectivamente representan radicales de carbono lineales o ramificados teniendo 1 - 27 atomos de carbono, por lo que el numero de atomos de carbono de R1 y R2 es, a lo mucho, 28. La invencion tambien se refiere a eteres de poliolalquilo que se derivan de compuestos que tienen al menos tres funciones de hidroxi, o todas las funciones de hidroxi hasta que una es reemplazada por un grupo de la formula general (VIII). La invencion se refiere ademas a dichos eteres de polioalquilo como agentes tensioactivos y dichos agentes de lavado y limpieza conteniendo eteres de polioalquilo (ver formulas (I) y (VIII)).

    Abstract: The present invention relates to a process for preparing oligomers consisting mainly of repeating units derived from 1- or 2-butene from a hydrocarbon stream consisting substantially of branched and linear hydrocarbon compounds having 4 carbon atoms, and comprising olefinic branched and linear hydrocarbon compounds having 4 carbon atoms (C 4 starting stream) by a. in step a), separating the C 4 starting stream into a fraction consisting mainly of linear hydrocarbon compounds having 4 carbon atoms (l-C 4 fraction) and a fraction consisting mainly of branched hydrocarbon compounds having 4 carbon atoms (b-C 4 fraction), by contacting the C 4 starting stream with a membrane which is easier to pass for linear hydrocarbon compounds having 4 carbon atoms than for branched hydrocarbon compounds having 4 carbon atoms, b. in step b), optionally after removing butanes, oligomerizing the olefinic hydrocarbon compounds having 4 carbon atoms present in the l-C 4 fraction, c. in step c), subjecting the olefinic hydrocarbon compounds having 4 carbon atoms present in the b-C 4 fraction to one of the following steps: c1. reaction with methanol to give methyl tert-butyl ether (step c1) c2. hydroformylation to give substantially isovaleraldehyde (step c2) c3. polymerization to polyisobutylene (step c3) c4. dimerization to 2,4,4-trimethyl-1-pentene (step c4) c5. alkylation, substantially to form saturated hydrocarbon compounds having 8 or 9 carbon atoms (step c5).
