Generating Fuel Energy by Catalytic Pyrolyzing of Microalgae
Abstract: In biomass pyrolysis process, a catalyst is used to modify the pyrolysis gases' chemical composition and increase the bio-oil fraction. This process uses the byproducts of thermal conversion processes. It is anticipated that the introduction of pyrolysis catalysts in the case of microalgae will lower the bio-oxygen oil's content and increase the number of added-value compounds in this liquid fraction. Catalysts can also help decrease the nitrogen in bio-oil. As …
