Verfahren zur selektiven Hydrierung von Alkinen |
摘要 |
<p>Alkynes are selectively hydrogenated in alkene rich hydrocarbon feeds, such as 1,3-butadiene-rich C4 cuts, by passing the hydrocarbon feed at least partially in liquid phase over a palladium-based catalyst in the presence of hydrogen, preferably in trickle mode, followed by passing the effluent, at least partially in liquid phase preferably containing about 300-400 ppmw alkynes, over a copper-based catalyst in the presence of hydrogen thereby producing a hydrocarbon product of significantly reduced alkyne concentration.</p> |
