Abstract: In situations where the demand for syngas is intermittent, a fuel processor is operated to provide a high absolute hydrogen and carbon monoxide production, rather than to give a high fuel-specific hydrogen and carbon monoxide production. When a syngas generator is operated to intermittently produce syngas, a heating process can be performed between periods of syngas demand in order to keep the fuel processor within a desired temperature range. The heating process can comprise various steps or events including performing a heating event, allowing a standby period, and/or performing a carbon conversion event. Carbon formed during the process of converting fuel to syngas can be advantageously converted to maintain the temperature of the fuel processor within a desired range in between periods of syngas demand. A predictive method can be employed to control at least a portion of the heating process.
