Effect of CoMo/HSO3-functionalized MCM-41 over Heavy Oil

Abstract

The potential of Co-Mo metals supported on functionalized MCM-41 as catalyst to hydrodesulfurization of heavy oil has been explored in this work. The MCM-41 functionalized sample was synthesized according to methods previously reported in the literature. Co and Mo metals were incorporated into the support by simultaneous impregnation. The catalyst was characterized by specific surface area and X-Ray Diffraction. The pore channel of MCM-41 was confirmed by transmission electronic microscopy and infra red spectroscopy. Catalytic activity tests were carried out using heavy oil from Gulf of Mexico. The API gravity was increased from 12.5 to 20.2, the kinematics viscosity was decreased from 18,700 to 110 cSt at 298 K, the contents of asphaltene and sulfur were also reduced. © 2010, Sociedad Química de México.
