METHODS AND SYSTEMS FOR GENERATING A SOURCE OF CARBON DIOXIDE FOR CONSUMPTION IN AN AUTOTROPHIC BIOREACTOR

摘要

Methods and systems for producing a biomass precursor to a biofuel using feedstock including carbon dioxide captured from ambient air are disclosed. In some embodiments, the methods include the following: capturing carbon dioxide from ambient air; transferring the carbon dioxide to a solution thereby forming a carbon-enriched solution; providing predetermined minerals; and feeding the carbon-enriched solution and the predetermined minerals to predetermined autotrophic microorganisms capable of oxidizing the predetermined minerals. In some embodiments, the systems include the following: a carbon dioxide collector including filter units for capturing carbon dioxide from ambient air; a regeneration unit for rinsing the filter units thereby transferring the carbon dioxide captured by the filter units to a solution thereby forming a carbon-enriched solution; and an interface unit including a vessel for containing the carbon-enriched solution and a conduit for supplying the carbon-enriched solution to an autotrophic bioreactor.
