Syngas Cleanup

Syngas generated from biomass inherently contains a high concentration of CO2 (typically greater than 20%). The high CO2 concentration negatively impacts downstream catalytic processing. The level must be reduced when the desired products involve oxygenated products such as methanol and DME.

SGT's cleanup technology centers on the development of silica membranes that will separate CO2 from syngas generated from the gasification of biomass. SGT’s new syngas cleanup and ratio adjustment methods employ SGT's membrane technology, which preferentially removes those acid gas contaminants (H2S, CO2) which can adversely impact downstream catalytic processing. SGT's cleanup technology centers on the development of silica membranes, which will separate CO2 from syngas, generated from the gasification of biomass.

Most biomass gasification systems operate at low pressure with high levels CO2. The product syngas must be compressed for use in turbine or catalytic processing. SGT's membrane removes CO2, reducing compression cost, and improving the heating value of the syngas. For high pressure gasification, SGT’s membrane technology will secure significant economic benefits related to CO2 removal.
