Water/Carbonate Stripping For CO2 Capture Adsorber Regeneration And CO2 Delivery To Photoautotrophs

摘要

The invention provides systems and methods for the delivery of carbon to photoautotrophs. The invention utilizes low energy regeneration of adsorbent for CO₂ capture and provides for effective CO₂ loading into liquids useful for photoautotroph growth and/or production of photosynthetic products, such as biofuels, via photoautotrophic culture media. The inventive system comprises a fluid/membrane/fluid contactor that provides selective transfer of molecular CO₂ via a dense (non-porous) membrane from a carbonate-based CO₂ snipping solution to a culture medium where the CO₂ is consumed by a photoautotroph for the production of biofuels, biofuel precursors or other commercial products.
