Shrnutí:[Display omitted] •Hierarchical ZSM-5 was synthesized through a solvent-free method.•Nanocalcite increases the hierarchical porosity level of ZSM-5.•The increase in hierarchy enhances the overall catalytic performance.•Green gasoline with high aromatic content and high RON was obtained. Hierarchical zeolites have emerged as a promising way to realize renewable fuel production through a sustainable route due to their enhanced mass transfer. However, their current preparation techniques usually require complicated as well as long synthesis periods. This research aims to create a hierarchical ZSM-5 zeolite through a green and facile method, i.e., solvent-free method, and evaluate its performance in gasoline production from palm oil. Zeolite with 2 – 8 nm mesopore size (SFZ) was successfully produced from this route. Moreover, the addition of nano calcite during the synthesis increases the hierarchy level of zeolite due to the presence of a macro-sized cavity (Temp-SFZ). These two samples exhibit superior activity and selectivity compared to the commercial sample (Com-HZ), which is usually synthesized through a hydrothermal method, i.e., Temp-SFZ > SFZ > Com-HZ. Notably, the Temp-SFZ sample produces the highest liquid yield (up to ∼ 42 %) with > 90 % gasoline content and 112 of RON (Research Octane Number). Moreover, the aromatics were also high (>90 %) with a minimum coke formation (2.51 %).
