Abstract
The invention relates to a process of activating a supported acid catalyst, and consists in the conversion of Lewis acid-type acid sites which are deposited on a solid substrate into activated acid sites in a non-oxydizing acid medium. The catalyst is exposed to a phase of activation in a medium containing a holohydric acid or a halohydric acid precursor, in the presence of at least one preferably parafinic hydrocarbon or hydrocarbon derivative, at a temperature greater than 20° and preferably between 100° C. and 250° C., and at a pressure of between 10,and 50,10,Pa, for a length of time sufficient to ensure conversion into activated acid sites.
