Abstract
The use of microalgae as a feedstock to produce hydrocarbon fuels using high pressure catalytic pyrolysis was studied. In this study, freeze dried microalgae species Nannochloropsis oculata was studied as the biomass source for py-rolysis in a micro-reactor. Algae sample was characterized by thermo gravimetric analysis (TGA) as well as FTIR analysis. To augment the hydrocarbon fraction, the effects of temperature and pressure were studied by varying the temperature from 500-800 oC in 100 oC increments and pressure 0-150 psi in 50 psi increments. When the sample was heated from 500-800 oC the volatiles were mainly hydrocarbons with small percentage of oxygenated and nitrogenated species. It was found that the gases evolved within 100-500oC were mostly oxygenated, nitrogenated and sulfided species.
