Appeal No. 1997-1593
Application No. 08/469,685
APPENDIX
1. A method for reacting a feed gas to produce a product
and separating the product from unreacted feed gas, the method
comprising the steps of:
a) providing a plurality of compartments connected in
series, wherein each compartment comprises a reaction zone
which includes a reaction zone inlet port connected to feed
gas line and a carrier gas line, and a separation zone which
includes an upstream section connected to a downstream section
with a separation zone recovery port for recovering product
passing through the connection between the upstream and the
downstream sections; and said downstream section including at
least one separation zone outlet port; and wherein the
compartments are connected so that each of the separation zone
outlet ports is connected to the reaction zone inlet port of
the next compartment downstream in the series and the last
compartment in the series is connected to the first
compartment of the series to provide a closed loop;
b) supplying pressurized feed gas to the reaction zone
inlet port of a first one of the compartments in the series
and pressurized carrier gas to the reaction zone inlet port of
the preceding compartment upstream in the series so that the
feed gas reacts in the reaction zone of said first one of the
compartments to produce a mixture which includes a product and
unreacted feed gas, and so that the mixture is passed to the
upstream section of the separation zone of said first one of
the compartments wherein product is separated from unreacted
feed gas so as to effect a substantially simultaneous reaction
and separation and so that the unreacted feed gas exits the
separation zone outlet port;
c) transferring carrier gas and unreacted feed gas
exiting the separation zone outlet port of said first one of
the compartments to the reaction zone inlet port of the next
compartment in the series;
d) at a time after the unreacted feed transfer of step
(c), recovering the product from the separation zone recovery
port of said first one of the compartments;
