METHOD OF OPERATION OF PROCESS TO PRODUCE SYNGAS FROM CARBONACEOUS MATERIAL

摘要

A process is provided for producing syngas that is effective for use in downstream processes. The process for producing syngas includes operating a gasification apparatus in a start-up mode until the gasification apparatus and equipment downstream of the gasification apparatus are adequately warmed up to a first target temperature. Upon reaching a first target temperature, the process is then operated in a production mode to produce a second syngas with a higher CO/CO2 molar ratio. Operation in a start-up mode until reaching a first target temperature, provides a process that is effective for reducing fouling in downstream equipment and for providing a second syngas can be more effectively cooled and cleaned.

1. A process for producing syngas, the process comprising:
gasifying carbonaceous material to provide a first syngas having a CO to CO2 molar ratio of less than about 0.5 until the first syngas reaches a first target temperature; and upon reaching the first target temperature, gasifying carbonaceous material to provide a second syngas having a CO to CO2 ratio of greater than the first syngas.
