Abstract
A method of purification and dealkylation of alkylaromatic hydrocarbons consisting in: contacting these hydrocarbons in a plurality of reaction zones with a highly active chromium-alumina catalyst, adjusting the temperature of the effluent from each of said reaction zones before to enter the next successive reaction zone so that the reaction temperature in each zone, as a result of the exothermic reaction produced in it, is maintained below a maximum value of 665º c, the number of these zones being sufficient to effect the conversion of at least 50% by weight of said charged alkylaromatic hydrocarbons and to provide a total contact time of 30 to 130 seconds, the reaction conditions in each zone comprising a ratio of hydrogen to aromatic products of 3: 1 as minimum; said catalyst containing from 15 to 25% of incorporated in an alumina base obtained by dehydrating hydrated alumina containing at least 50% beta-trihydrate.
