PROCESS FOR REDUCING THE BROMINE INDEX OF A HYDROCARBON

A process for reducing the bromine index (BI) of a hydrocarbon feedstock, for example an aromatic hydrocarbon feedstock. Removal of contaminants, more specifically bromine-reactive contaminants such as unsaturated hydrocarbons (e.g. olefins) cause the reduction in the bromine index (BI) of the hydro...

Beschreibung
Zusammenfassung:	A process for reducing the bromine index (BI) of a hydrocarbon feedstock, for example an aromatic hydrocarbon feedstock. Removal of contaminants, more specifically bromine-reactive contaminants such as unsaturated hydrocarbons (e.g. olefins) cause the reduction in the bromine index (BI) of the hydrocarbon feedstock. The process involves providing an adsorbent, such as zeolite. La présente invention concerne un procédé destiné à réduire l'indice de brome (BI) d'une charge d'alimentation en hydrocarbures, par exemple une charge d'alimentation en hydrocarbures aromatiques. L'élimination de contaminants, plus particulièrement de contaminants réactifs au brome tels que des hydrocarbures insaturés (par exemple des oléfines) provoque la diminution de l'indice de brome (BI) de la charge d'alimentation en hydrocarbures. Le procédé comprend l'étape consistant à fournir un adsorbant, tel qu'une zéolithe.
