Biofuel Production From Nannochloropsis Oculata Microalgae in Seawater Without Harvesting and Dewatering Over Alumina-Silicate Supported Nickel Catalysts
(Elsevier, 2018) Deliismail, Özgün; Özdoğru, Bertan; Şeker, Erol
The aim of this work was to study the production of biofuels from marine Nannochloropsis oculata without harvesting and dewatering over the single step sol-gel made alumina-silicate supported nickel catalysts at 80 °C and 1.0 atm. Sulfuric acid, hydrochloric acid, and nitric acid were used in the sol-gel to study the effect of acid type on catalyst activities. The catalyst made using sulfuric acid resulted in 74% microalgae conversion as compared to the catalysts made with other acids. Treatment of this catalyst with ~35 g of NaCl per kg of water at 80 °C and 1.0 atm for 24 h increased microalgae conversion to 91.5% under the same reaction condition and the bio-fuels ranging from mono/polysaccharides, polyols to esters and fatty acids were produced. This study showed that nickel and 25.1 ?mol/g of total acidity and acidic strength having 130–380 °C of temperature range was necessary to achieve 91.5% conversion. © 2018 Elsevier Ltd
