CARBON NANO-TUBE PRODUCTION FROM CARBON DIOXIDE |
摘要 |
Disclosed is a method for making carbon nanotubes comprising (a) reducing a nickel containing catalyst with a reducing agent in a first reaction chamber, (b) contacting the nickel containing catalyst with carbon dioxide under conditions sufficient to produce a reaction product, (c) transferring the reaction product to a second reaction chamber, wherein the second reaction chamber comprises a Group VIII metal containing catalyst, and (d) contacting the Group VIII metal containing catalyst with the reaction product under conditions sufficient to produce carbon nanotubes, wherein the first and second reaction chambers are in flow connection during the transfer step (c), wherein the only source of carbon used to form the carbon nanotubes is from the carbon dioxide used in step (b), and wherein at least 20% of the carbon from the carbon dioxide used in step (b) is converted into carbon nanotubes. |

1. A method for making carbon nanotubes comprising:
(a) reducing a nickel containing catalyst with a reducing agent in a first reaction chamber; (b) contacting the nickel containing catalyst with carbon dioxide under conditions sufficient to produce a reaction product; (c) transferring the reaction product to a second reaction chamber, wherein the second reaction chamber comprises a Group VIII metal containing catalyst; and (d) contacting the Group VIII metal containing catalyst with the reaction product under conditions sufficient to produce carbon nanotubes, wherein the first and second reaction chambers are in flow connection during the transfer step (c), wherein the only source of carbon used to form the carbon nanotubes is from the carbon dioxide used in step (b), and wherein at least 20% of the carbon from the carbon dioxide used in step (b) is converted into carbon nanotubes. |
