        In connection with water-gas experiments, a process has been adapted for producing synthesis gas for the Fischer-Tropsch process by combining the Lane process of H₂ production with the normal water-gas process.  The Lane process consists of the alternate reduction and oxidation at 700°-800° C. of calcined spathic Fe ore, the reduction being effected by water gas and the oxidation with production of H₂ by steam.  The Research Board process involves removing the checking brickwork from the tar cracking chamber and its replacement by spathic Fe ore.  The temperature of the ore is raised to 700°-800° by the flow gases and is then reduced by passing through it the water gas produced during the up-run.  The spent gas from this reduction (calorific value 200 B.t.u. per cu. ft.) is collected in a separate gas holder.  H₂ is produced by passing the back-run steam through the reduced ore, a part of the steam being decomposed by the reduced Fe ore with the production of H₂ and the excess steam passed to the generator containing coke, where normal water gas is made.  The finished gas contains 32.3% of CO and 61.9% of H₂.
