Abstract
The invention is directed to the use of dissolved hydrogen in a purification process for the removal of Bromine Index (BI)-reactive compounds from an aromatic-containing hydrocarbon stream derived from various sources, such as petroleum fractionation, reforming, thermal cracking, catalytic cracking, isomerization, transalkylation, alkylation, coking, conversion of oxygenates, conversion of biomass, etc. The purification process comprises contacting the aromatic-containing hydrocarbon stream in the liquid phase in the presence of dissolved hydrogen with at least one suitable catalytic material under conditions effective to provide a product stream having a lower concentration of BI-reactive compounds than the untreated stream.
