Abstract
Nowadays, the aviation fuel demand is increasing as a result of the rise in global air traffic. The current aviation fuel (or called aviation gasoline) used for piston engines are mainly produced from petroleum which calls for more study to develop fuel from renewable resources such as edible and non-edible oil. Conversely, petroleum-based aviation fuel has a negative impact on the environment, mainly through the emission of greenhouse gas (GHG). In order to reduce this GHG emission, catalytic deoxygenation is a selected process that has been developed in converting renewable resources to renewable aromatic and drop-in fuel. Catalyst is one of the essential parts for chemical reactions to occur in the deoxygenation process, which could affect inhibit side reaction, reaction rate, product composition and biofuel quality. In producing high quality of bio-fuel, modified zeolite-based catalysts have been studied in deoxygenation of edible oil. Use of catalysts in the deoxygenation process can increase the yield of bio-aviation fuel via the deoxygenation process by improving efficiency and reducing coke formation. Moreover, the use of catalyst also resulted in the decrease in oxygen contents of bio-aviation fuel and consequently increases in its heating value. Several types of heterogeneous zeolite catalysts have been reported for widely used as the catalyst for the petroleum and petrochemical industry. Therefore, a heterogeneous catalyst such as zeolite catalyst is chosen as an availability catalyst for bio-aviation fuel production. Therefore, it is a priority to study zeolite catalyst by using various low-cost metal (including molybdenum and nickel) via precipitation technique of catalyst preparation on targeting a high yield of kerosene carbon number fuel.
