Patent Title: Process for removing aromatic compounds which are polycyclic and sulfur present in crude oil or distillates thereof
Publication date: 2005
Publication number: MXPA/a/2002/004975

Abstract: The present invention relates to a process for removing aromatic polycyclic compounds, which contain sulfur and are present in oil fractions or solubilized in organic solvents. The removal involves the use of selective adsorbents, which are polymeric matrices with a high cross-linking action and porosity. The sulfur compounds are adsorbed in a recognition site and released by washing the adsorbent with polar solvents. The invention describes the synthesis procedures of polymers, which consist in methods of molecular printing so as to generate matrices with selective recognition sites for target molecules;the same are of a thiophenic nature i.e., thiophene derivatives:dibenzothiophene, a dibenzothiophene sulfone, benzothiophene, 4,6-dimetyl dibenzothiophene, benzonaphtothiophenes, etc. The process may also be applied for removing compounds with heterocycles of six members, which contain two sulfur atoms such as thianthrene, thiols or mercaptants
