Abstract:
     A carbon deposit resistant catalyst for oxygen-free aromatization of methane is prepared from transition metal element in VI B family as active component (1-15 wt.%), zeolite molecular sieve as carrier and element in VI A family as assitant (0.1-10 wt.%) through drying and calcining raw powder of molecular sieve; ion exchange of carrier in solution containing ammonium ions, drying and calcining; high-temp steam treating to obtained carrier; modifying the carrier with element in VI family; immersing in solution containing transition element in VI B family; and drying and calcining obtained carrier. Its advantages are higher reaction activity and output rate of arene, stronger carbon deposit resistance, and high high-temp reaction stability.
