Hydrorefining method |
摘要 |
The hydrorefining method of the invention is characterized by contacting, in the presence of hydrogen, a fuel stock comprising normal paraffins and oxygen-containing compounds, with a hydrorefining catalyst comprising a support containing USY zeolite and at least one solid acid selected from among silica-alumina, alumina-boria, silica-zirconia, silica-magnesia and silica-titania, and at least one metal selected from among metals of Group VIb and metals of Group VIII of the Periodic Table supported on the support. |

1. A hydrorefining method, comprising:
contacting, in the presence of hydrogen,
a fuel stock produced by Fischer-Tropsch synthesis and comprising normal paraffins and oxygen-containing compounds, the fuel stock comprising gasoline stocks, anda hydrorefining catalyst comprising a support containing USY zeolite and at least one solid acid selected from among silica-alumina, alumina-boria, silica-zirconia, silica-magnesia and silica-titania, and at least one metal selected from among metals of Group Vlb and metals of Group VIII of the Periodic Table supported on the support; to convert oxygen-containing compounds to paraffins and to isomerized n-paraffins; wherein a molar ratio of silica/alumina in the USY zeolite is 10-200; wherein the proportion of the USY zeolite is 15% by mass or less based on the total amount of the support; and wherein the lightening rate of light fraction components with a boiling point of below 40° C. at a reaction temperature of 300° C. is no greater than 6% by mass. |
