Abstract

HYDROTREATING OF NAPHTHA (HDS) IS AN IMPORTANT UNIT IN CRUDE OIL REFINERIES IN WHICH COMPOUNDS SUCH AS SULFUR, NITROGEN, OXYGEN AND METAL ARE REMOVED. A COMMONLY USED HDS CATALYST IS COBALT-MOLYBDENUM ON ALUMINA SUPPORT. MODELING AND SIMULATION OF AN ISOTHERMAL FIXED BED REACTOR FOR NAPHTHA HYDROTREATING WAS CARRIED OUT. BASED ON THE FACT THAT THIOPHENIC COMPOUNDS ARE LESS REACTIVE THAN OTHER SULFURIC COMPOUNDS, THE TWO COMMON COMPOUNDS KNOWN AS BENZOTHIOPHENE AND THIOPHENE ARE CONSIDERED AS THE MAIN REACTANTS. THE FEED IS NAPHTHA FROM A CATALYTIC CRACKING UNIT WHICH HAS 7 PPM OF THIOPHENE AND 63 PPM OF BENZOTHIOPHENE. THE REACTOR IS OPERATING AT 220OC, 1.6 MPA, 3.5 H-1 LIQUID HOURLY SPACE VELOCITY AND A H2/OIL RATIO OF 338 NL/L. THE MATHEMATICAL MODEL DEVELOPED PROVED TO BE EFFICIENT AND OF PROPER COMPATIBILITY WITH THE EXPERIMENTAL DATA. THE SLIGHT DIFFERENCES ARE MAINLY BECAUSE OF THE KINETIC PARAMETERS USED IN THE REFERENCE ARTICLE.
