Abstract

A catalyst for full catalytic oxidizing of petroleum hydrocarbon in order to decrease the pollution of fuel is prepared through preparing solution A by complexing the chromium nitrate, manganese nitrate, iron nitrate and cobalt nitrate with citric acid, preparing solution B of nickel nitrate, copper nitrate and cerium nitrate, mixing them together, immersing Al2O3-SiO2 carrier in it, drying, heating and cooling.

Description

technical field [0001] The invention relates to a catalyst, which is especially suitable for the complete oxidation of C11-C20 wide-component petroleum hydrocarbons. Background technique [0002] In the oxidation of hydrocarbons, the research on the oxidation of liquid hydrocarbons has a very long history, but the purpose of the previous research was to obtain incomplete oxidation products, and complete oxidation was not the goal pursued before. Retrieval, relevant Chinese patents include: [0003] Catalysts for the oxidation of alkanes (application number 00126383.8); [0004] Alkane oxidation method (application number 97195087.3); [0005] Catalyst for oxidative dehydrogenation of lower alkanes and method for producing olefins (application number 99106660.X); [0006] An alkane oxidation catalyst and its preparation method (application number 96104766.6). [0007] Representative patents on catalysts for catalytic combustion of gasoline include: ...
