      Production of synthesis gas of a wide range of H₂:CO ratios in a Hygirtol-type (Girdler Corp.) furnace is described.  Operating data are presented for H₂:CO ratios of 2:1 and 1:1.  H₂ and CO mixtures containing 33-90% CO are produced by the reaction of natural gas (C_1.17H_4.3) with steam and CO₂.  No trouble was encountered at any time with C deposition on the catalyst.  The catalyst used was a Ni base catalyst furnished by the Girdler Corp. under the designation F-5.  The product gas has such a low CO₂ content that its removal is not required, thus reducing plant-construction cost.
