Investigation of the temperature influence on the catalytic hydrogenation upgrading of bio-oil using industrial nickel based catalyst RZ409.

ABSTRACT: Temperature and catalyst are critical factors influencing the catalytic hydrogenation of bio-oil. This study employed the industrial Ni-based catalyst RZ409 as the research subject and systematically evaluated its applicability at various reaction temperatures (200, 250, 280, 300, and 330 °C). The oil phase yield, oil properties, and chemical composition were analyzed to determine the optimal temperature. Thermogravimetric analysis (TG), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), and Brunauer-Emmett-Teller (BET) surface area analysis were utilized to evaluate the influence of temperature on the carbon deposition characteristics of the catalyst. Results showed that the optimum temperature of catalyst RZ409 is 300 °C. At this temperature, the weight factor (WF)
