Currently, Euro 5 (no more than 10 ppm sulfur content) and 6 (less diesel motor fuels are produced worldwide. High-quality by removing compounds using a hydrodesulfurization process. This article is devoted to the study of fuel containing 120 in presence an Al-Ni-Mo-O catalyst with 98% purification rate. According Langmuir–Hinshelwood–Panchenkov theory, kinetic model process developed calculati...
In this study, conditions were determined to obtain a solid wax with waxy ester content of more than 25% from the hydrotreating palm oil. The experiments conducted in pilot-scale fixed-bed reactor. influence temperature, liquid hourly space velocity (LHSV), and pressure on conversion triglycerides evaluated using nickel molybdenum catalyst (NiMo/Al2O3). variables between 240 260 °C, 1 2 h−1 41 ...
a novel acrylic acid-functionalized fe3o4 magnetic nanoparticle with a core-shell structure was developed for utilization as a heterogeneous organosuperacid in chemical transformations. the structural, surface, and magnetic characteristics of the nanosized catalyst were investigated by various techniques such as transmission electron microscopy (tem), thermogravimetric analysis (tga), and ft-ir...
in this thesis, we exploit a simple and suitable method for immobilization of copper(ii) complex of 4?-phenyl-terpyridine on activated multi-walled carbon nanotubes [amwcnts-o-cu(ii)-phtpy]. this nanostructure was characterized by various physico-chemical techniques. to ensure the efficiency and fidelity of copper species, the implementation of three-component strategies in click-chemistry all...
A three-phase nonisothermal heterogeneous model for describing the hydrotreating reactions in a trickle-bed reactor with complete catalyst wetting was solved. It includes correlations for determining solubility data, mass-transfer coefficients, and properties of the compounds under operating conditions. The model, based on the two-film theory and mass-transfer resistance at the gas-liquid and l...
Tall oil fractions obtained from Norwegian spruce pulping were hydrodeoxygenated (HDO) at pilot scale using a commercial NiMo hydrotreating catalyst. Comprehensive two dimensional gas chromatography (GC×GC) showed that HDO of both tall oil fatty acids (TOFA) and distilled tall oil (DTO) produced highly paraffinic hydrocarbon liquids. The hydrotreated fractions also contained fatty acid methyl e...
