Abstract

The objective of this work was to evaluate the O2 production and CO2 emission in an integrated process. The experiments were performed in a bubble column photobioreactor with a volume of 2 L, luminous intensity of 15 µmol/m2/s, aeration of 1 VVM with air injection enriched with 15% carbon dioxide. The photobioreactor was integrated into a bio-combustion furnace designed on a laboratory scale, where the emissions were evaluated. The fuel used was petroleum coke. The experimental conditions in the were: initial coke mass 1.0 g, total combustion time of 20 min, and airflow 1.0 L/min. A gas chromatograph to determine greenhouse gas emission was used. The results showed a CO2 capture and O2 production in the photobioreactor of 0.46 and 0.40 kg/m³, respectively. Furthermore, the CO2 emissions in the furnace were 0.71 kg/m³. In this sense, the photobioreactor demonstrated the ability to capture carbon and produce bioproducts, and when integrated into a bio-combustion process, presented the potential to mitigate greenhouse gas.
