Dynamic catalytic conversion reactor and systems and methods using the same

A method for catalytic CO2 conversion comprising:

• (i) supplying a feed gas into one or more of a plurality of zones in a dynamic catalytic conversion reactor, the dynamic catalyst conversion reactor comprising:
• an outer wall having an inner portion filled with a plurality of tubes arranged in parallel to the longitudinal axis of the outer wall;
• a catalyst within each of the plurality of tubes;
• and
• one or more separating sheets within the outer wall,
• wherein the one or more separating sheets divide the inner portion of the outer wall into the plurality of zones, and
• wherein each of the plurality of zones comprises a portion of the plurality of tubes,
• wherein the feed gas comprises a carbon source gas comprising CO2, and hydrogen gas;
• (ii) contacting the feed gas and the catalyst in the feed gas zones to cause a CO2 conversion reaction;
• and
• (iii) producing a reactor effluent from the CO2 conversion reaction.

A method of preserving catalyst activity within a dynamic catalytic conversion reactor comprising:

• an outer wall having an inner portion filled with a plurality of tubes arranged in parallel to the longitudinal axis of the outer wall;
• a catalyst within each of the plurality of tubes;
• and
• one or more separating sheets within the outer wall,
• wherein the one or more separating sheets divide the inner portion of the outer wall into a plurality of zones, and
• wherein each of the plurality of zones comprises a portion of the plurality of tubes,
• the method comprising:
• supplying a feed gas into one or more of the plurality of zones in the dynamic catalytic conversion reactor, wherein the feed gas comprises hydrogen gas;
• contacting the feed gas and the catalyst within the plurality of tubes in the feed gas zone to cause a chemical reaction;
• and
• supplying either:
• i) one or more gases into one or more idle zones in the dynamic catalytic conversion reactor that are not supplied with the feed gas;
• or ii) one or more bleed streams from the feed gas into one or more idle zones in the dynamic catalytic conversion reactor that are not supplied with the feed gas.
