Abstract

Because the traditional commercial catalyst NiMoS2/γ-Al2O3 contained sulfur lead to the product and the environment are polluted by sulfur In addition precious metal catalysts such as Pd/C are too expensive Therefore in this study the production of non-sulfide catalysts is mainly developed and palm oil is converted into hydro-processed renewable diesel (HRD) First the catalysts with different supports (γ-Al2O3 and SAPO-11) and metals (Ni and Mo) are compared in experiments Through different temperature pressure H2-to-oil ratio and weight hourly space velocity (WHSV) using GC-MS/FID and GC-TCD to explore the composition of liquid and gas products Analyze the conversion rate selectivity and yield and study the best experimental conditions for this catalyst After the catalyst is deactivated it is regenerated by calcining Use XRD TGA FTIR and Nitrogen adsorption/desorption isotherm to analyze the characteristics of fresh deactivated and regenerated catalysts Finally test the fuel characteristics of HRD (including: cetane number autoignition temperature flash point and smoke point)
