Abstract
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 80â¯Â°C and 1.0â¯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 ~35â¯g of NaCl per kg of water at 80â¯Â°C and 1.0â¯atm for 24â¯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 25.1â¯Î¼mol/g of total acidity and acidic strength having 130-380â¯Â°C of temperature range was necessary to achieve 91.5% conversion.
