High Acidity and Low Carbon-Coke Formation Affinity of Co-Ni/ZSM-5 Catalyst for Renewable Liquid Fuels Production through Simultaneous Cracking-Deoxygenation of Palm Oil

This study investigates the effect of chemically doped Co and Ni metals on ZSM-5 catalyst with respect to catalysts’ characteristics performance for palm oil cracking. Some characterization methods have been conducted identify physicochemical properties synthesized catalysts, including X-ray diffraction (XRD), Scanning Electron Microscopy (SEM), N2-physisorption, NH3- CO2-probed Temperature Programmed Desorption (NH3-TPD CO2-TPD) methods. The deposited carbon-coke spent catalysts is analysed using simultaneous thermal gravimetric – differential scanning calorimetry (TG-DTG-DSC) analysis. was evaluated cracking process in a continuous fixed-bed catalytic reactor at 450 °C. To determine liquid product composition functional group components, we used Attenuated Total Reflectance Fourier-transform Infrared Spectroscopy (ATR-FTIR) batch distillation methods, respectively. We found that metal chemically-doped Ni/SM-5 catalyst, resulting increase acidity decrease basicity. conversion increases as ratio highest triglyceride (76.5%) obtained 3Co-Ni/ZSM-5 yield gasoline, kerosene, diesel 2.61%, 4.38%, 61.75%, It also doping Ni/ZSM-5 decreased formation due low Overall, it proven combination Ni, which doped, has good activity affinity high catalyst.
