Abstract:
1. A vapor phase process for selective removal of at least 80 mole % of acetylenic impurities from an input gaseous stream including one or more hydrocarbons, acetylenic impurities and steam, comprising: contacting said input stream in the vapor phase at a temperature in the range of from 250° C. (480° F.) to 900° C. (1650° F.) with a solid catalyst comprising Ni, Fe, an alkali metal, and optionally an alkaline earth element wherein said Ni present in an amount of 0.25-20 wt % on a dry basis of said catalyst, Fe is present in an amount of 30-75% on a dry basis of said catalyst and recovering an output stream wherein said output stream lacks at least 80 mole % of said acetylenic impurities, wherein the input stream is selected from streams (a), (b), (c), (d) or (e): wherein stream (e) comprises less than 50 mol % C4 hydrocarbons based on the hydrocarbon content of the input stream.
