Abstract: Improvement in the efficiency of carbon dioxide reduction reaction is achieved. A gas supply unit having a plurality of pores is established in a lower portion of a reduction chamber, and carbon dioxide is supplied as bubbles into an aqueous solution. This can elevate a concentration of carbon dioxide dissolved in the aqueous solution without stirring the aqueous solution using a stirring bar, and render the concentration uniform in the aqueous solution. Therefore, the efficiency of reduction reaction of carbon dioxide in a reduction electrode can be improved.

Abstract: Nitrogen in a form suitable for feeding a population of microbes in a bioreactor is produced by reacting nitrogen gas and hydrogen gas to form ammonia plus an unreacted gas stream under conditions favorable to having little unreacted nitrogen gas in the unreacted gas stream. The ammonia, or a compound derived from the ammonia is fed to the microbes and the unreacted gas stream is optionally fed back into the reaction, or fed into the bioreactor. Oxygen can be produced, such as by electrolysis, and also provided to the microbes. Hydrogen from the electrolysis can be added to the hydrogen being reacted with nitrogen gas, and/or can be added to the bioreactor. Where nitrogen gas is produced from air separation, the residual gases can be another source of oxygen.
