GRADED NICKEL ALLOY CATALYST BEDS AND PROCESS FOR PRODUCTION OF SYNGAS

摘要

A method is disclosed for converting light hydrocarbons to synthesis gas employing a reduced nickel alloy monolith catalyst which catalyzes a net partial oxidation reaction to produce an effluent stream comprising carbon monoxide and hydrogen in a ratio of about 2:1 H2/CO. Preferred catalyst beds comprise a compositionally graded axial array, or stack, of Ni-Cr, Ni-Co-Cr, or Ni-Rh monoliths, and their manner of making is disclosed. The Ni alloy monolith catalysts are mechanically strong and retain high activity and selectivity to carbon monoxide and hydrogen products under syngas production conditions of high gas space velocity, elevated pressure and high temperature.
