Abstract

SAMPLES OF THE VR2ROR5R CATALYSTS SUPPORTED ON MULTIWALL AS WELL AS; SINGLEWALL CARBON NANOTUBES (MWCNT AND SWCNT) WERE SYNTHESIZED VIA HYDROTHERMAL METHOD FOR THE OXIDATIVE DEHYDROGENATION OF PROPANE (ODHP) TO PROPYLENE. THE VANADIUM CATALYSTS SUPPORTED ON CNTS WITH THE C/V MOLAR RATIO OF 1:1 WERE PREPARED. THE CATALYSTS WERE CHARACTERIZED BY THE XRD, FTIR, HR2R-TPR, FESEM AND UV-VIS DIFFUSE REFLECTANCE SPECTROSCOPY. THE PERFORMANCE OF THE PREPARED CATALYSTS AND THE BARE SUPPORTS WERE SUBSEQUENTLY EXAMINED IN A FIXED-BED REACTOR. THE MAIN PRODUCTS WERE PROPYLENE, ETHYLENE, AND COX. THE VANADIUM CATALYST SYNTHESIZED HAD THE BEST PERFORMANCE UNDER THE REACTOR TEST CONDITIONS OF 450OC, FEED CR3RHR8R/AIR MOLAR RATIO OF 0.6 AND THE TOTAL FEED FLOW RATE OF 90ML/MIN RESULTING IN AVERAGE VALUES OF 37.97% AND 30.59% FOR PROPYLENE SELECTIVITY AND PROPANE CONVERSION, RESPECTIVELY. RESULTS UNDER CONDITIONS IN COMPARISION WITH OPEN LITERATURE VALUES REVEALED SATISFACTORY PERFORMANCE.
