Description
Algae have been identified as a potential feedstock for biofuels production. Flash hydrolysis (FH) is a process that extracts proteins from algae while protecting algae’s lipids (oils). FH of Scenedesmus sp. yields results that can inform the mass balance of Carbon, Nitrogen, and Phosphorus (C:N:P). The mass balance is used to characterize the extraction of C:N:P to the lipid (solids) and aqueous phases from biomass. A slurry mixture of Scenedesmus sp. is pumped through a continuous flow, subcritical water (280°C) reactor to extract nitrogen (proteins) and other nutrients (P) while protecting the lipids for biofuels production. Analyses used to construct the mass balance were: Total Nitrogen and Total Organic Carbon (TN/TOC) of collected supernatant, Elemental Analysis (EA) of freeze dried lipid solids and supernatant, and phosphorous analysis using APHAP Method 4500-P B.4, F. C:N:P mass balance was then constructed to determine extraction percentages.
