Hidrodesulfuración de crudos pesados
Abstract
The hydrodesulfurization of heavy crudes by the influence of hydrogen and catalyst was studied. It was demostrated that the hydrodemetallization, hidrogen pressure, the process temperature, the rotational velocity and the crude-catalyst ratio are important over the process. The crude oil from Orinoco Oil belt show reductions of 76,9% in sulfur, 85% in viscosity and the final specific gravity is 13,1 °API.
