THE EXISTING CONVERSION PATHWAY FOR BIO-JET FUEL RANGED CYCLOALKANES INVOLVES A SERIES OF HETEROGENEOUS CATALYSIS, WHICH USUALLY OCCUR AT HIGH OPERATING TEMPERATURES (150-300 C) AND HIGH H2 PRESSURES (UP TO 5 MPA) IN PRESENCE OF SUPPORTED METAL CATALYSTS. HOWEVER, THE AS-PREPARED HETEROGENEOUS CATALYSTS OFTEN SUFFER THE PROBLEMS OF AGGREGATION AND LEACHING-OUT OF ACTIVE SPECIES DUE TO THEIR HIGH SURFACE ENERGY AND WEAK INTERACTION WITH THE MATRICES, WHICH INEVITABLY LEAD TO REDUCED CATALYTIC ACTIVITY AND REUSABILITY. TO REDUCE THE ENERGY AND HYDROGEN DEMAND AND IMPROVE THE CATALYTIC PERFORMANCE OF BIO-JET FUEL RANGED CYCLOALKANES PRODUCTION, WE PROPOSE A NEW CATALYST DESIGN BY LEVERAGING AN ENVIRONMENTAL-FRIENDLY NATURE MOLECULES, NANOCRYSTALLINE CELLULOSE (NCC), A ROD-LIKE NANOCRYSTALS WHICH CAN BE SOURCED FROM ANY AGROFORESTRY WASTES. IT IS EXPECTED THAT THE PRESENCE OF ABUNDANT REDUCING FUNCTIONAL GROUPS (E.G. HYDROXYL AND EHTER) CAN STABILIZE METAL NANOPARTICLES IN A HIGHLY MONODISPERSED FORM, THUS REDUCE THE CHANCE OF AGGLOMERATION AND LEAD TO THE IMPROVEMENT OF CATALYTIC ACTIVITY AND RECYCLABILITY. THE OBTAINED METAL-NCC NANOPARTICLES IS EXPECTED TO CATALYZE HYDROGENATION OF AROMATICS INTO CYCLOALKANES AT ROOM TEMPERATURE AND REDUCED H2 PRESSURE. OUR PROPOSED PROJECT IS TRANSFORMATIVE IN TWO WAYS: 1) WE PRESENT AN EMERGING NEW INNOVATIVE IDEA TO CREATE A "GREEN CATALYST" THAT CAN POTENTIALLY BE USED FOR BIO-JET FUELS PRODUCTION WITH LESS ENERGY INPUT AND H2 CONSUMPTION COMPARED TO THE STATE-OF-THE-ART HYDROTREATING PROCESS; AND 2) BY USING CUTTING-EDGE SEPARATION AND ENZYMATIC HYDROLYSIS APPROACHES, WE ARE APPLYING NEW KNOWLEDGE AND APPROACHES TO SOLVE THE CHALLENGES IN THE STATE-OF-THE-ART OF NANOCRYSTALLINE CELLULOSE EXTRACTION.
