Claim Text:
1. A process for reducing the diolefin and oxygenate content of a liquefied C 2 -C 5 hydrocarbon, the process comprising feeding the liquefied hydrocarbon to a vessel containing a solid adsorbent disposed on a support thereby adsorbing the diolefins and oxygenates on the adsorbent, wherein the support is a monolithic support and solid adsorbent is disposed on microcells of the monolithic support and wherein the solid adsorbent is ZSM-5, ZSM-11, ZSM-12, ZSM-23, ZSM-35, ZSM-38, or ZSM-48; and passing the liquefied hydrocarbon of reduced diolefin and oxygenate content to an amine absorber unit, wherein the amine absorber unit reduces the hydrogen disulfide content of the liquefied hydrocarbon with less foaming in the amine absorber unit as compared to a liquefied hydrocarbon without reduced diolefin and oxygenate content.
