Abstract
The present disclosure provides a method for the separation of a gas constituent from a gaseous mixture. The disclosure also provides polyethylene glycol disubstituted siloxane based solvents for use in the method. These solvents are of use for pre-combustion COcapture and are capable of replacing glycol-based solvents while offering operation at a higher temperature region. These solvents are also of use for generation of hydrogen from reformed natural gas or syngas, adjusting CO/Hratio for Coal & Biomass to Liquids, removal of COfrom syngas for coal & biomass to NH/Fertilizer, natural gas sweetening, and upgrading of landfill and biogas.
