Titania-zirconia mixed oxide was developed as support for Mo, CoMo and NiMo catalysts. Synthesis was carried out using evaporation induced self assembly and modified sol-gel templating route. The samples were calcined in a temperature range of 400C to 600C. SEM and porosity analyses were used to ensure that the mesostructure is stable after Mo and promoter incorporation. Wide-angle XRD was used...

Reduction of harmful emissions in the combustion of fossil fuels imposes tighter specifications limiting the sulfur content of fuels. Hydrodesulfurization (HDS) is a key process inmost petroleumrefineries inwhich the sulfur ismostly eliminated. Themodeling and simulation of the HDS process are necessary for a better understanding of the process operation; it is also a requirement to optimize pr...

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 spite of the huge worldwide interest for single-atom and ultradispersed catalysts, metal atoms coordinated with sulfur are rarely addressed. this work, molybdenum-based catalysts were obtained by adsorption three thiomolybdates different nuclearity (n = 1, 2, 3) on high-surface-area S-doped carbon, followed sulfidation in H2S/H2 flow at 350 °C. Scanning transmission electron microscopy (STEM...
