Role of Ni-Fe/ZSM-5/SAPO-11 bifunctional catalyst on hydrodeoxygenation of palm oil and triolein for alternative jet fuel production

This study aims to investigate the effect of four bifunctional catalysts S1 = (ZSM-5/SAPO-11), S2 = (5%Ni/ZSM5/SAPO-11), S3 = (5%Fe/ZSM-5/SAPO-11), and S4 = (5%Ni-Fe/ZSM-5/SAPO-11) on the hydrodeoxygenation of palm oil and triolein for alternative jet fuel production. All catalysts were synthesized...
