Abstract
Process for the alkylation of paraffinic and/or aromatic hydrocarbon feedstock with an olefinic alkylating agent by contact with a perfluorinated alkyl sulphonic acid movably adsorbed within a confined area of a fixed bed of particle contact material, wherein the fixed bed of particle contact material is subdivided in a number of elongated channels.
Claims4
A process for the alkylation of paraffinic and/or aromatic hydrocarbon feedstock, comprising the steps of:
- providing a fixed bed of particle contact material in a reactor body, wherein the interior of the reactor body is subdivided into a number of elongated channels each of which is filled with the particle contact material;
- adsorbing a liquid catalyst within the particle contact material in each channel;
- and
- delivering the paraffinic and/or aromatic hydrocarbon feedstock into the partitioned fixed bed reactor to contact the adsorbed catalyst to produce a moving reaction zone in each channel, such that each moving reaction zone maintains a substantially uniform thickness and a substantially uniform migration velocity across the width of the respective channel.
