Selection of the process flow for high water vapor ratio conversion reactions

There is a project that uses a space furnace for gasification; the dry basis content of CO after conversion is approximately 71%, and the water-to-gas ratio is around 1. The final product is synthetic ammonia, so it is necessary to convert as much of the CO as possible into H2. Due to the high CO content, there is a concern that the temperature might rise too much during the conversion process; therefore, it is planned to add a pre-conversion furnace in front of the main conversion furnace to help reduce the temperature increase in the bed of that furnace. I wonder whether pre-conversion is feasible in practice I’ve also heard that if too much pre-conversion catalyst is used, it can lead to overheating as well. Are there any other mature solutions?
Which manufacturer are you from? Currently, many manufacturers are operating space furnaces successfully; you can refer to the process used by Luxi Chemicals. In these space furnaces for gasification, the emission level is less than 0.4%, and they are also used for ammonia synthesis, with no overheating occurring at all.
