About this Abstract
Meeting 2017 TMS Annual Meeting & Exhibition
Symposium Pan American Materials Congress: Materials for Oil and Gas Industry
Presentation Title Adsorption of Organosulfur Compounds on Doped Boron Nitride Nanostructures
Author(s) Francisco Villanueva, Jose Luis Rivera, Pedro Navarro Santos
On-Site Speaker (Planned) Francisco Villanueva
Abstract Scope Dibenzothiophene (DBT) and its derivates are the main source of sulfur in oil. Commonly used hydrodesulfurization (HDS) processes eliminate most of those compounds through decomposition reactions. Alkyl derivates of DBT have proven to be hard to eliminate with the traditional processes. Adsorption of DBT and its derivates in boron nitride nanostructure doped with carbon atoms is proposed as an alternative/complementary process to HDS. The adsorption sites are the carbon atoms, which act as an attractive site for the free electron on the sulfur atom of the DBT derivates. The interaction between the DBTs and the nanostructures are studied through Density Function Theory calculations using the generalized gradient approximation GGA implemented in the VASP software. We report the complexation energies, conformations and separation between the sulfur atom and the carbon atoms in the nanostructure, and also studied the band gap change after complexation.
