Process for producing synthesis gas |
摘要 |
A process for producing a synthesis gas which comprises the steps of mixing a desulfurized light natural gas with steam; pre-heating the mixed gas; carrying out a first reforming reaction at a temperature of 500 to 750° C. under adiabatic conditions by bringing the gas into contact with a catalyst having a specific porosity in which a specific amount of nickel or a platinum group metal is contained as an active component in a carrier composed of CaO and Al2O3 and containing a specific amount of CaO, at least part of CaO forming a compound together with Al2O3, or a catalyst in which a specific amount of nickel is contained in an alpha-alumina carrier containing 98% by weight or more of aluminum oxide and having a specific porosity; and then carrying out a second reforming reaction in reformer tubes in a heating furnace. The light natural gas may be a gas obtainable by reacting a desulfurized heavy natural gas with steam.
