Abstract

A process and apparatus is described for continuously producing synthesis gas by a unique non-catalytic partial oxidation reaction. The gaseous reactants, typically natural gas as fuel and oxygen as oxidant are separately preheated by electrical heaters prior to mixing upon discharge from a swirling jet burner into a partial oxidation reactor. The resulting effluent gas stream is subsequently cooled in a quench chamber to produce a product gas. The flow rates of the natural gas and oxidant are adjusted in order to maintain a fuel equivalence ratio between about 2 to about 4. As a result the H2/CO ratio, CO selectivity, natural gas conversion and synthesis gas yield are obtained in a ratio of 0.6 to 1.0, 80 to 90%, 60 to 80% and 1.2 to 1.6, respectively. The resulting product gas may be used as synthesis gas, reducing gas, or fuel gas.
