Abstract: H-ZSM-5-supported cobalt is widely used as a catalyst for hydrodeoxygenation (HDO) and hydroisomerization (HI) of fatty acid methyl esters (FAMEs). Nevertheless, ZSM-5 has a high proportion of micropores and a long diffusion path that might cause pore blockage in fatty acid-related processes. To overcome this, modifications of its structure into sheet-like material have been investigated using these steps (i) Ureamodification for sheet-like structure (ii) Secondary growth for fabricated nanosheet by acid/base treatment and seeding methods. The result showed that the ZSM-5 structure was developed into a b-axis oriented structure which provides a sheet-like structure with a b-axis length of 590 nm after modification with the mole of urea at 160 and Si/Al at 100. The catalyst performance on FAMEs conversion was 97.72%. Furthermore, a shorter b-axis length of 330 nm was obtained by implementing the 0.5 M of the HCl etching and secondary growth approach. The catalyst exhibited a 99.69% FAMEs conversion, 89.38% liquid yield, and product selectivity towards 35.78% n-alkanes, 37.47% iso-alkanes, and 19.71% of jet fuel
