Appeal No. 97-3640
Application No. 08/406,272
BACKGROUND
The appellant's invention relates to a process for substantially removing CO from a CO2 2
containing C -C olefin fluid stream by (1) adding water to the fluid to form a water-containing fluid;
2 6
and, (2) contacting the water-containing fluid with a composition comprising an alkali metal compound
and/or an alkaline earth metal compound, wherein the water and composition are each present in an
amount effective to substantially remove CO . Claims 1, 12 and 23 are illustrative of the claimed
2
subject matter.
1. A process comprising the steps of:
(1) adding water to a fluid to form a water-containing fluid; and thereafter
(2) contacting said water-containing fluid with a composition which comprises
an oxygen-containing metal compound selected from the group consisting of an alkali
metal compound, an alkaline earth metal compound, and combinations of two or more
thereof; wherein said fluid comprises at least one C -C olefin and carbon dioxide; the
2 6
physical form of said fluid is selected from the group consisting of gas, liquid, and
combinations thereof; said process is carried out under conditions sufficient to
substantially remove said carbon dioxide from said fluid; and said composition and said
water are each present in an effective amount to substantially remove said carbon
dioxide from said fluid.
12. A process according to claim 1 wherein said water-containing fluid is
saturated with water.
23. A process for substantially removing carbon dioxide from a fluid stream
comprising the steps of:
(1) adding water to a fluid to form a water-containing fluid stream; and
thereafter
(2) contacting said water-containing fluid stream with a substantially solid
composition under conditions sufficient to substantially remove said carbon dioxide
from said fluid stream wherein said fluid stream comprises an olefin selected from the
