Process for oxidizing mercaptans to disulfides in the presence of solid catalytic masses
Abstract
Abstract A PROCESS FRO CONVERTING SULFUR COMPOUNDS IN PETROLEUM CUTS TO DISULFIDES COMPRISES CONTACTING THE PETROLEUM CUT WITH MOLECULAR OXYGEN AND WITH A SOLID CATALYTIC MASS INSOLUBLE INTHE LIQUID PETROLEUM CUT AND CONSISTING ESSENTIALLY OF AT LEAST ONE SOLID PHTHALOCYANINE OF A TRANSITION METAL, A SOLID CARRIER AND A SOLID ALKALI METAL OXIDE OR HYDROXIDE, THE AMOUNT OF THE TRANSITION METAL PHTHALOCYANINE BEING BETWEEN 0.05% AND 50% BY WEIGHT WITH RESPECT TO THE CARRIER WEIGHT AND THE AMOUNT OF THE ALKALINE METAL OXIDE OR HYDROXIDE BEING BETWEEN 10% AND 50% BY WEIGHT WITH RESPECT TO THE TOTAL WEIGHT OF THE CATALYTIC MASS. BY THE PROCESS, THE HERETOFOR CONVENTIONAL PRETREATMENT STEP OF MIXING THE PETROLEUM CUT WITH AN ALKALINE AQUEOUS PHASE IS NO LONGER NECESSARY.
