  • Desulfurization catalyst for catalytic cracked gasoline and method for desulfurizing catalytic cracked gasoline using the same
    Patent number: 8048293
    Abstract: The desulfurization catalyst for catalytic cracked gasoline according to the present invention has high performance in removal of sulfur compounds in gasoline fractions. This catalyst contains particulate vanadium oxide having the average particle diameter in the range from 0.1 to 10 ?m at the content in the range from 0.3 to 3 weight % calculated as that of V2O5. The porous spherical particles of inorganic oxide are made of crystalline aluminosilicate zeolite and a porous inorganic oxide matrix, and furthermore contain antimony.
    Type: Grant
