A process for recovering benzene, the process including: feeding hydrogen and a hydrocarbon fraction comprising benzene, components lighter than benzene, components heavier than benzene, and diolefins to a catalytic distillation reactor system comprising at least one reaction zone comprising a hydrogenation catalyst; concurrently in the catalytic distillation reactor system: contacting the diolefins and hydrogen in the presence of the hydrogenation catalyst to selectively hydrogenate at least a portion of the diolefins; and fractionating the hydrocarbon fraction to form a fraction comprising benzene and other C6 hydrocarbons, and a heavies fraction comprising C7+ hydrocarbons; recovering the heavies fraction from the first catalytic distillation reactor system as a bottoms fraction; and withdrawing the fraction comprising benzene and other C6 hydrocarbons from the catalytic distillation reactor system as a benzene concentrate fraction. |
