ABSTRACT: Thisstudyrigorouslyinvestigatesbiomassthermalbehaviorandgasificationefficiencyusingnaturalzeolite
(NZ) catalysts, specifically focusing on those modified with nickel. Objectives encompass the assessment of Si/Al ratio,
surface area, and pore characteristics of zeolite catalysts. Thermogravimetric Analysis exposes distinct temperature
dependent biomass behaviors, emphasizing nickel?s catalytic influence, notably in Ni/NZMC at 471.95?C, indicating
enhanced thermal interactions linked to cellulose decomposition. Structural changes due to nickel impregnation
are detailed through X-ray diffraction patterns, revealing shifts in peak heights and Si/Al ratios. The syngas
composition analysis highlights Ni/NZMC?s exceptional hydrogen production. Gasification yield results underscore
zeolite catalysts? positive impact, particularly Ni/NZMC, exhibiting superior efficiency with increased gas yield and
higher hydrogencontent. Thisresearchchallengesconventional beliefs, unveiling a nuanced relationship between Si/Al
ratio, specific surface area, and gasification results, emphasizing the multifaceted nature of catalyst performance. These
f
indings significantly contribute to understanding catalyst-driven biomass conversion, providing a strong foundation
for sustainable energy advancements.
