Abstract:
     A catalyst for aromatizing low-carbon paraffin is prepared from transition metal in VI B family as main active component (0.2-15 wt.%), zeolite molecular sieve as carrier, halogen-family element as modifier (0.1-10 wt.%) through drying and calcining raw powder of molecular sieve; ion exchange of carrier with solution containing ammonium ions, drying and calcining; immersing in solution containing transition element in VI B family; drying and calcining obtained carrier; immersing in solution containing halogen-family element; and drying and calcining obtained carrier. Its advantages include higher carbon deposit resistance and benzene selectivity, and high activity to aromatization of propane.
