    摘要： 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.

    摘要： A process for the sulfiding of a hydrodesulfurization catalyst for example in a distillation column reactor. The catalyst in the distillation column reactor is first dried using nitrogen and the reactor is filled with a sulfiding solvent and circulation begun. The reactor is heated to a temperature above the decomposition temperature of the sulfiding agent to be used and the sulfiding agent charged to the reactor. When sulfiding agent breakthrough is noted in the overheads the temperature is raised and held until sulfiding is complete.
