Desulfuración de combustibles a través de redes metal-orgánicas bimetálicas

Abstract

Petroleum-derived fuels are an essential source of energy in our daily lives. However, upon combustion, the sulfur compounds present in oil produce sulfur oxides that are harmful to human health and the environment. Therefore, the desulfurization of fuels is crucial to reduce environmental damage. Metal-organic 3 frameworks are a class of highly porous materials that have recently been used as catalysts and adsorbents in the removal of sulfur compounds. It is important to mention that the incorporation of a second metal in metal-organic networks can create bimetallic materials with unique desirable properties in the desulfurization of fuels. In this document, we seek to provide an overview of metal-organic networks and materials based on bimetallic metal-organic networks in hydrodesulfurization, oxidative desulfurization, pervaporative desulfurization, and adsorptive desulfurization processes. In addition, this work aims to compare the attraction between a series of metals in a node of MOF and dibenzothiophene using density functional theory. All of this is with the purpose of establishing the theoretical bases for the design and development of organic materials used in fuel desulfurization.
