  • Patent number: 7217850
    Abstract: The invention relates to a process for the production of phenylalkanes comprising an alkylation reaction of at least one aromatic compound by at least one linear olefin having from 9 to 16 carbon atoms per molecule. Said reaction is carried out in a catalytic reactor in which n reaction zones are present each containing at least one same solid acid catalyst, n being greater than or equal to 2, and at the inlet to each of which at least one fraction of the total quantity of olefins necessary for said reaction is introduced. The phenylalkanes obtained by the process according to the invention are particularly suitable for manufacturing detergents.

  • Publication number: 20060287562
    Abstract: A process for the production of phenyl alkanes by catalytic alkylation on a solid acid catalyst employs at least one moving-bed reactor. This process comprises a catalytic alkylation stage of an aromatic compound by at least one olefin that has 9 to 16 carbon atoms per molecule, combined with a catalyst reactivation circuit. Each reactor contains n reaction zones, whereby each of said zones consists of an acidic solid catalyst, optionally different from one zone to the next. Entering each reaction zone, a fraction of the total amount of olefins necessary to the alkylation reaction is introduced. The phenyl alkanes that are obtained by the process according to the invention are particularly suitable for the production of detergents.

  • Publication number: 20060122446
    Abstract: A reaction device with staged zones making it possible to implement strongly endothermic or exothermic reactions. The device reduces the differences in catalytic activity between these zones using an addition of fresh or regenerated catalyst at the inlet of each reaction zone and provides an integrated heat exchanger. A process of chemical conversion employs the device for gas-phase and/or liquid-phase exothermic or endothermic reactions, and in particular for the oligomerization reaction of C2 to C12 fractions for the purpose of producing a diesel fraction.

  • Patent number: 6506702
    Abstract: The invention concerns a process for regenerating a catalyst in a fixed bed, for example a catalyst for reforming or for aromatic compound production, including a step for monitoring and controlling combustion completion which is carried out after the catalyst has undergone all of the combustion steps of the process. The monitoring and control step is carried out by injecting an oxygen-containing gas into the zone where monitoring and control takes place, the monitoring and control step being carried out under conditions which are more severe than those in the combustion steps. The monitoring and control step is carried out with an oxygen consumption of less than 10%. The temperature advantageously remains substantially constant.
