Líquido de depuración de polisiloxano para eliminar compuestos de tipo alquitrán

摘要

Tar-like components can be removed from gas streams resulting from gasification of coal, waste or biomass by contacting the gas with a liquid organic aryl polysiloxane. The polysiloxane preferably contains alkyl groups and aryl groups, and is in particular a polymethyl polyphenyl polysiloxane. The gas comprises one or more of hydrogen, carbon monoxide, carbon dioxide, and methane.
