(716c) Investigation of Carbon Content Analysis of Chlorella vulgaris and Nannochlropsis Oculata Using TOC Analyzer for CO2 Bioremediation and Biofuel Production Conference: AIChE Annual MeetingYear: 2015Proceeding: 2015 AIChE Annual MeetingGroup: Innovations of Green Process Engineering for Sustainable Energy and EnvironmentSession: Unconventional Technologies for CO2 Capture, Conversion and Utilization Time: Thursday, November 12, 2015 - 1:20pm-1:45pm Authors: Razzak, S., King Fahd University of Petroleum and Minerals Ali, S., Hossain, M. M., King Fahd University of Petroleum & Minerals Binous, H., King Fahd University of Petroleum & Minerals Global warming is become a current issue that world seek to find a solution to it through mitigation of the greenhouse gases. Carbon dioxide (CO2) is one of the well-known greenhouse gases, which mainly came from human activities because of industrialization. Different CO2 capture strategies have been suggested and the most attractive one is the combined carbon capture and wastewater treatment using microalgae. Microalgae can utilize CO2 to increase its biomass which can be converted to a valuable biofuel products by conversion methods whether its thermochemical, biochemical, or chemical reaction based technology. Thus, characterization of the microalgae biomass for its carbon content is a decisive criterion for the selection suitable of conversion method. TOC analyzer is used to measure total organic carbon for Chlorella vulgaris, Nannochloropsis oculta, microalgae species. The effect of CO2 concentration in the growth of microalgae and the amount of carbon produced is investigated. The increasing of the carbon content during microalgal biomass growth is well determined.Acknowledgements: The authors would like to acknowledge the support provided by King Abdulaziz City for Science and Technology (KACST) for funding this work through project No. # KACST-ARP- A-T-23-26 (KACST-ARP#T-K-11-0431).
