Abstract[English]
The present invention relates to the preparation of a catalyst containing a specific organic additive, the catalyst comprising a support based on a mesoporous alumina containing boron, in which the boron precursor is introduced into the alumina by impregnation, the alumina having previously undergone a hydrothermal treatment step. As a result of its advantageous properties, the catalyst comprising a support based on an alumina containing boron can be used in all refining processes and also as an adsorbent, in particular for catalytic processes used to treat hydrocarbon fractions, such as the hydrotreatment of vacuum distillates.[French]
La présente invention se rapporte à la préparation d'un catalyseur additivé avec un additif organique spécifique comprenant un support à base d'une alumine mésoporeuse contenant du bore dans lequel le précurseur de bore est introduite par imprégnation sur ladite alumine ayant préalablement subi une étape de traitement hydrothermale. Ledit catalyseur comprenant un support à base d'une alumine contenant du bore, du fait de ses propriétés intéressantes, peut être utilisée dans tous procédés de raffinage ainsi que comme adsorbant, en particulier pour les procédés catalytiques traitant des coupes hydrocarbonées telles que l'hydrotraitement de distillats sous vide.
