Abstract
Zr-containing SiO2 and their parent catalysts were fabricated with different methods using EDTA chelation and template-assist. The activity of the catalysts was explored in crude palm oil (CPO) hydrocracking, conducted under a continuous system micro-cylindrical reactor. The conver- sion features and the selectivity towards biofuel products were also examined. The physicochemical of catalysts, such as structure phase, functional groups, surface morphologies, acidity features, and particle size, were investigated. The study showed that the template method promoted the crystal- line porous catalysts, whereas the chelate method initiated the non-porous structure. The catalysts’ acidity features of SiO2 and SiO2/Zr were affected by the preparation, which revealed that the EDTA chelate-assisted method provided higher acidity features compared with the template method. The CPO hydrocracking study showed that the SiO2/Zr-CEDTA provided the highest catalytic activity towards the hydrocracking process, with 87.37% of conversion attained with 66.29%.wt of liquid product. This catalyst exhibited selectivity towards bio-jet (36.88%), bio-diesel (31.43%), and bio- gasoline (26.80%). The reusability study revealed that the SiO2 /Zr-CEDTA had better stability to- wards CPO conversion compared with SiO2/Zr-CEDTA, with a low decrease in catalyst perfor- mance at three consecutive runs.
