8.5. Syngas Composition for IGCC netl.doe.gov

Also, natural gas consists mainly of methane (CH 4), whereas syngas consists mainly of CO and hydrogen (H 2). The H 2 composition of the syngas results in a higher flame speed and broader flammability limits, meaning the syngas produces a stable flame at leaner conditions than natural gas and the combustion speed is much quicker than natural gas. This more rapid combustion speed What kind of syngas is used in IGCC?What kind of syngas is used in IGCC?Syngas Composition for IGCC Syngas for use in integrated gasification combined cycle (IGCC) applications must be free of contaminants such as particulates and trace metals which could cause damage to the gas turbine.8.5. Syngas Composition for IGCC netl.doe.gov What's the difference between syngas and natural gas turbines?What's the difference between syngas and natural gas turbines?The combustor requires a specified heat input to maintain performance, so a significantly higher flow rate is required for syngas than natural gas for a similar turbine size. Also, natural gas consists mainly of methane (CH 4 ), whereas syngas consists mainly of CO and hydrogen (H 2 ).8.5. Syngas Composition for IGCC netl.doe.gov

Why is the H 2 ratio high in syngas?Why is the H 2 ratio high in syngas?The syngas H 2 :CO ratio is relatively high (>0.7), typical of a slurry-feed gasification system. The high levels of COS during the earlier years of operation were a result of problems with the COS-hydrolysis unit (specifically, catalyst poiing by trace metals and chlorides and surface area degradation by overheating).5.1.5. Syngas Composition netl.doe.gov5.1. Gasification Introduction netl.doe.gov

Composed primarily of the colorless, odorless, highly flammable gases carbon monoxide (CO) and hydrogen (H 2), syngas has a variety of uses. The syngas can be further converted (or shifted) to nothing but hydrogen and carbon dioxide (CO 2) by adding steam and reacting over a5.1.2.

5.1.5. Syngas Composition. The figure of gasification reactions and transformations illustrated the concept of coal gasification, and noted resulting composition of syngas. This can vary significantly depending on the feedstock and the gasification process involved; however typically syngas is 30 to 60% carbon monoxide (CO), 25 to 30% hydrogen (H 2 ), 0 to 5% methane (CH 4 ), 5 to 15% carbon 5.1.6.
