Selective hydrogenation of alkynyl-containing compounds and polyunsaturated compounds

摘要

A selective hydrogenation process that is particularly effective in selectively hydrogenating alkynl compounds, such as acetylene or methyl acetylene, over alkenyl compounds, such as ethylene, is described. The process utilizes a slurry conversion unit for heat efficiency purposes during the conversion of acetylene into ethylene.

主权项

1. An acetylene conversion method comprising:
combining acetylene, molecular hydrogen, carrier fluid and catalytic particles to produce a slurry having an acetylene concentration of at least 2 mol % in a slurry conversion unit; and exposing the slurry to operating conditions that include a conversion rate of at least 2 moles/hour/cc of the catalyst particles and an average hydrogenation reaction temperature greater than or equal to 125° C. to produce a vapor product comprising ethylene; and extracting heat from the slurry conversion unit via indirect heat exchange with a utility fluid.
