<p>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. Certain preferred catalysts comprise bulk Ni-Cr, Ni-Co-Cr or Ni-Rh alloys. A method of making a bulk nickel alloy catalyst includes depositing a combination of chromium and cobalt metals, or rhodium metal, onto a nickel metal substrate and then thermally diffusing the Cr and Co coating, or the Rh coating, into the atomic lattice of the nickel substrate to produce a bulk Ni-Co-Cr or Ni-Rh alloy monolith catalyst. Preferred 3-D catalyst configurations include perforated foil, metal gauze, metal foam and expanded metal. The catalysts are mechanically strong and self-supporting, and retain high activity and selectivity to carbon monoxide and hydrogen products under syngas production conditions of high flow rate, superatmospheric pressure and high temperature.</p> |
