Chemical and microalgal conversion of carbon dioxide into fuels and materials: a review
摘要
The rapid climate warming caused partly by rising carbon dioxide levels calls for efficient methods to capture and convert carbon dioxide into energy and chemicals. Here, we review microalgal carbon dioxide capture with focus on photosynthesis, chemical adsorbents and catalysts, factors controlling carbon sequestration, cultivation systems, artificial intelligence and modeling, and applications. Carbon sequestration is controlled by feed gas composition and flow rate, temperature, pH, light, humidity, dissolved oxygen, shear stress, nutrients, and species, e.g., green algae and cyanobacteria. Microalgal biomass can be converted into biofuels, pharmaceuticals, biopolymers, and food.
