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 …

Functionally Graded Natural Fibre and SiC-reinforced Polymer Composite: Mechanical Properties
Abstract: Multifunctional materials, also called functionally graded materials (FGMs), are based on natural fibres or fillers and vary in composition and/or microstructure to control functional, structural, or thermal, properties. Functionally graded materials (FGMs) have been created for use in spacecraft, aircraft, and other engineering applications because they can withstand extremely high temperatures. Particle-reinforced FGMs, which make up the majority of FGMs, are made differently depending on their position. The mechanical and …
