Abstract
An amino-siloxane composition is presented. The amino-siloxane composition includes structure (I): wherein R1 is independently at each occurrence a C1-C5 aliphatic radical; R2 is a C3-C4 aliphatic radical; R3 is a C1-C5 aliphatic radical or R4, wherein R4 comprises structure (II): and X is an electron donating group. Methods of reducing an amount of carbon dioxide in a process stream using the amino-siloxane composition are also presented.
Claims8
A method of reducing the amount of carbon dioxide in a process stream, comprising the step of contacting the process stream with a carbon dioxide absorbent composition which is substantially free of a co-solvent, said carbon dioxide absorbent composition comprising an amino-siloxane comprising structure (I):
- wherein R1 is independently at each occurrence a C1-C5 aliphatic radical;
- R2 is a C3-C4 aliphatic radical;
- R3 is a C1-C5 aliphatic radical or R4, wherein R4 comprises structure (II):
- and X comprises a R5O— group;
- a (R5)2N— group;
- a R5S group;
- or a morpholine group, wherein R5 is independently at each occurrence a C1-C5 aliphatic radical.
The method according to claim1, wherein the process stream comprises syn-gas.
A method of reducing the amount of carbon dioxide in a process stream, comprising the step of contacting the process stream with a carbon dioxide absorbent composition which is substantially free of a co-solvent, said carbon dioxide absorbent composition comprising an amino-siloxane having structure (Ib):
- wherein R1 is independently at each occurrence a C1-C5 aliphatic radical;
- and X comprises a R5O— group;
- a R5S group;
- a (R5)2N— group;
- or a morpholine group, wherein R5 is independently at each occurrence a C1-C5 aliphatic radical.
