Abstract
A process comprising (i) providing a gaseous stream including greater than 1% by volume carbon dioxide; (ii) providing water; (iii) converting the carbon dioxide and the water to an organic intermediate and oxygen gas in the presence of light; (iv) separating the oxygen gas from the organic intermediate; and (v) converting the organic intermediate to ethylene and carbon dioxide after said step of separating the oxygen gas from the organic intermediate.

A process comprising:
- (i) providing a gaseous stream including greater than 1% by volume carbon dioxide;
- (ii) providing water;
- (iii) converting the carbon dioxide and the water to an organic intermediate and oxygen gas in the presence of light;

3 more elements
A system for producing ethylene, the system comprising:
- (i) a first bioreactor including photosynthetic microorganisms that convert carbon dioxide to an organic intermediate, said first bioreactor having a carbon dioxide inlet and an outlet for the organic intermediate;
- and
- (ii) a second bioreactor in fluid communication with the first bioreactor and including microorganisms that convert the organic intermediate produced in the first bioreactor to ethylene, said second bioreactor having an outlet for gaseous materials including ethylene, and said second bioreactor having an outlet for fluid materials including unreacted organic intermediate.
