Abstract

The invention relates to a process for selectively hydrogenating an alkyne to the corresponding alkene comprising a step of contacting a gaseous feed comprising hydrogen and 0.1 to 20 mass % of alkyne with a catalyst comprising at least one Group 10 element on a boron-modified support. The process shows high conversion and good selectivity, and can be stably operated also if the feed comprises more than 2 mass % of alkyne.
