Abstract
A method is disclosed for removing the small fractions of acetylenic compounds from a mixed hydrocarbon stream, the improvement consisting in that said stream is treated with an organic acid in the presence of an acidic ion-exchange resin, preferably an --SO.sub.3 H containing resin, the acidic groups of said resin having totally been exchanged with alkali metal ions or alkaline earth metal ions. Acetic acid (glacial, anhydrous) is the preferred acid.
Claims15
A method for the removal of acetylenic compounds contained in inorganic or organic hydrocarbon streams, characterized in that an organic acid is added to said acetylenic compounds in the presence of an acidic ion-exchange resin, the acidic groups of which have been totally exchanged with both mercuric ions and ions of alkali metal or alkaline earth metals.
A method according to claim, 1 wherein the ions of the alkali metals, or alkaline earth metals are added to the resin in the form of their salts or hydroxides.
A method according to claims, 1 wherein the reaction is carried out at a temperature ranging between 20.degree. C and 120.degree. C.
A method according to claim, 1, wherein the addition reaction is carried out in the liquid phase.
