Abstract

The excessive emission of pollutants to the atmosphere has been a problem during the last few decades due to, among other reasons, the massive use of transports. In order to avoid this problem, many methods are being investigated as an alternative to the classical hydrodesulfurization technique, such as adsorption, biodesulfurization, extraction and oxidation.The extractive desulfurization is one of the most promising alternatives. Moreover, its enhancement with selective oxidation of sulfur compounds has been a trending field of research over the last years. Oxidative desulfurization (ODS) method has proved to be one of the most leading processes for removal of sulfur as it operates under ambient conditions, doesn’t consume huge amount of energy.This work deals with the desulfurization of model fuel with sulfur content 500 ppm and real oil with sulfur concentration 2% at mild conditions using prepared Al-based MOF as catalyst. Al-based metal-organic framework (MOF) with high surface area and porosity has been synthesized hydrothermally using waste polyethylene terephthalate bottles (PET) containing terephthalic acid as an organic linker. The prepared Al based MOFs have been characterized by means of Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), scanning electron microscope (SEM), transmission electron microscopy (TEM), X-ray photo-electron spectroscopy (XPS) and nitrogen adsorption–desorption analysis. The catalytic activity of the green-prepared Al-MOF was evaluated in the oxidative desulfurization (ODS) of modeled and real oil samples. The different reaction parameters (temperature, time, catalyst dose, oxidant loading and ultrasounds) on the ODS performance have been studied and optimized.
