Industrial high-temperature reformer and reforming method

Abstract

An industrial high temperature reformer and the reforming method in which a temperature of the reforming furnace is maintained at 1000° C. or higher by burning the coke, and a temperature of at least an upper half of the reforming furnace is maintained at 1200° C. or higher by burning the syngas, thereby producing syngas at a capacity of 500 m 3 /hour or more by reforming all carbonaceous feedstock which is supplied to the reforming furnace.

1 . An industrial high temperature reforming method comprising:
 a first step of supplying coke to the reforming furnace;   a second step of supplying a first oxygen to the reforming furnace, and maintaining a temperature of the reforming furnace at 1000° C. or higher by burning the coke with the first oxygen;   a third step of supplying steam to the reforming furnace;   a fourth step of maintaining a temperature of at least an upper half of the reforming furnace at 1200° C. or higher by burning at least one of a gas mixture and a first syngas, with a second oxygen; and   a fifth step of supplying carbonaceous feedstock to the reforming furnace, and generating a second syngas by reforming the carbonaceous feedstock,   wherein the gas mixture is generated through the burning of the coke and the steam, and the first syngas is supplied to the reforming furnace.   
     
     
         2 . The industrial high temperature reforming method of  claim 1 , wherein the oxygen used to burn the coke at the second step is supplied via a lower section of the reforming furnace, and the oxygen used to burn at least one of the gas mixture and the first syngas at the fourth step is supplied via a mid-section of the reforming furnace. 
     
     
         3 . The industrial high temperature reforming method of  claim 1 , wherein the first syngas at the fourth step is part of the second syngas generated at the fifth step, and the high temperature syngas generated at the fifth step pyrolyzes the carbonaceous feedstock and is then cooled. 
     
     
         4 . The industrial high temperature reforming method of  claim 1 , wherein two carbonaceous feedstock inlets are formed in a mid-section of the reforming furnace, and a second oxygen inlet is formed between the two carbonaceous feedstock inlets.
