A process for reducing the Bromine Index of a hydrocarbon feed containing bromine -reactive contaminants that has improved cycle length and utilizes a crystalline molecular sieve catalyst. The process is carried out by contacting the hydrocarbon feed under conversion conditions with a catalyst shaped in the form of an elongated aggregate comprising a crystalline molecular sieve having a MWW or *BEA framework type. The shortest cross-sectional dimension of the elongated aggregate is less about 1/10 inch (2.54 millimeters).
L'invention concerne un procédé pour réduire l'indice de brome d'une alimentation en hydrocarbures contenant des contaminants réactifs avec le brome qui a une longueur de cycle améliorée et utilise un catalyseur tamis moléculaire cristallin. Le procédé est effectué en mettant en contact une alimentation en hydrocarbures dans des conditions de conversion avec un catalyseur sous forme d'un agrégat allongé comportant un tamis moléculaire cristallin ayant une ossature de type MWW ou *BEA. La plus courte dimension en coupe transversale de l'agrégat allongé est inférieure à environ 2,54 millimètres (1/10 pouce).
