The production of biofuels as an alternative to fossil fuels has been a signi cant challenge until recently.The present work focuses on hydrocracking used cooking oil (UCO) into biogasoline over chromium impregnated on a sulfated mesoporous silica catalyst. The effects of varying sulfuric acid concentration, calcination temperature, and impregnated chromium content (wt%) were systematically studied in the synthesis process employing TEOS and NaHCO 3 by sol-gel method. A sulfuric acid concentration of 2 M and calcination temperature of 600 ˚C produced an SO 4 -SiO 2 catalyst with the best acidity of 8.46 mmol g -1 . Variation of chromium content (wt%) of 1% had Cr/SO 4 -SiO 2 catalyst with the best acidity of 8.57 mmol g -1 . SiO 2 , SS 2-600, and Cr-SS 1 catalyst were tested for their performance in the hydrocracking of UCO into biogasoline at an optimum temperature of 450 °C, H 2 gas ow rate of 20 mL min -1 , and catalystto-feed ratio (wt%) of 1:100. Hydrocracking using Cr-SS 1 catalyst produced the most liquid product of 37.14% with the highest gasoline fraction selectivity of 29.38%.

“…Indonesia and other tropical nations have sizable agricultural industries that produce substantial amounts of agricultural waste ideal for biomass energy production. For instance, residues from the production of rice, coconut oil, sugarcane, and palm oil can be effectively transformed into biofuels, [13,24,26] biogas, [12,14,27] hydrogen (H 2 ), [16,28,29] and electricity. [30,31] Additionally, the extended growing seasons in tropical areas provide a steady supply of biomass all year long, serving as a dependable source of feedstock for bioenergy generation.…”

“…Catalysts play a crucial role in producing renewable energy from biomass, significantly enhancing the efficiency and selectivity of the involved chemical reactions. [24][25][26]28] Biomass, a complex and heterogeneous material, necessitates intricate chemical processes for its conversion into valuable energy sources like biofuels. Catalysts facilitate these processes by lowering the activation energy required for the chemical process, enabling reactions to occur at lower temperatures and with reduced energy input.…”

Numerous concerns, including environmental impact and public health issues, drive the urgent need to replace nonrenewable fossil fuels with renewable energy sources, with biomass emerging as a viable alternative globally. In this comprehensive review, the urgent need to transition from nonrenewable fossil fuels to renewable energy sources is addressed, focusing on biomass as a global alternative. It examines the role of zirconium‐based catalysts in converting biomass into biofuels and hydrogen. Various biomass extraction methods based on the thermochemical processes (pyrolysis, gasification, hydrothermal liquefaction, hydrocracking, and steam reforming) are explored, including their merits and limitations. Additionally, the properties of zirconium‐based catalysts and their catalytic efficiency in biomass conversion are assessed, highlighting the factors influencing their performance. In this literature review, the promising potential of zirconium‐based catalysts in enhancing the sustainability and efficiency of global biofuel production from biomass is revealed. It underscores the critical role of biomass as a renewable energy source and highlights the significance of zirconium‐based catalysts in advancing sustainable biofuel production. It offers insights into addressing environmental concerns, promoting public health, and supporting the global transition toward renewable energy solutions.
