Abstract

See full text

Systems and methods for operating a gasifier are provided. The method can include combusting a first start-up fuel to produce a first combustion gas. A temperature within the gasifier can be increased from a starting temperature to at least an auto-ignition temperature of a second start-up fuel by introducing the first combustion gas to the gasifier. A second start-up fuel can be introduced directly to the gasifier after the temperature within the gasifier is at least the auto-ignition temperature of the second start-up fuel. At least a portion of the second start-up fuel can be combusted within the gasifier to produce a second combustion gas. The second combustion gas can produce sufficient heat to increase the temperature within the gasifier to a hydrocarbon feedstock gasification temperature. A hydrocarbon feedstock can be introduced to the gasifier. At least a portion of the hydrocarbon feedstock can be gasified within the gasifier to produce a syngas.
