Abstract A process for selectively hydrogenating the C2-C10 high-unsaturated hydrocarbons (alkyne and biolefin) at upstream of pre-depropanizing tower or pre-deethylanizing tower in olefin production features that the material stream comes in mixture-phase hydrogenation reactor for hydrogenating it and then in said pre-depropanizing tower or pre-deethylanizing tower. Its advantages include simple apparatus, and less coking and consumption of energy.
