1. A process for controlling a percentage of benzene in a hydrocarbon feed stream comprising benzene, the process comprising:
mixing the hydrocarbon feed stream with an alkylating agent and a sulfiding agent to obtain a mixed hydrocarbon feed stream; and
routing the mixed hydrocarbon feed stream and hydrogen gas to pass over a catalyst in a catalytic reactor to obtain a processed hydrocarbon stream, wherein the catalyst comprises 15-25 wt % of group VIB metals and 4-7 wt % of group VIIIB metals, and wherein the process converts benzene into higher alkylated aromatic molecules and simultaneously results in hydrodesulfurization of the hydrocarbon feed stream in the catalytic reactor.
