Abstract
Systems and methods for the electrochemical conversion of COT to multi-carbon products are provided. Each system and method comprises a sequence of multiple, independently optimized electrochemical reaction steps that take place in separate reaction chambers.
Claims24
A method of electrochemical conversion of CO2 to a multi-carbon compound comprising:
- transferring CO2 from a CO2 source to a first reaction module via a first conduit that connects the CO2 source to the first reaction module;
- in the first reaction module, reacting the CO2 with water under first electrochemical reaction conditions sufficient to produce CO and hydroxide ions;
- transferring the CO to a second reaction module via a second conduit that connects the first reaction module and the second reaction module;
- in the second reaction module, reacting the CO with water under second electrochemical reaction conditions sufficient to produce the multi-carbon compound;
- and
- collecting the multi-carbon compound.

A modular system for the electrochemical conversion of carbon dioxide to a multi-carbon alcohol, comprising:
- a first electrolyzer module comprising a first catalyst that catalyzes the conversion of CO2 to CO;
- a second electrolyzer module comprising a second catalyst that catalyzes the conversion of CO to a multi-carbon compound;
- and
- a first conduit configured to transfer CO2 from a CO2 source to the first electrolyzer module;
- and
- a membrane configured to permit selective diffusion of the CO from the first electrolyzer module to the second electrolyzer module.
