Abstract

The present invention is one kind of catalyst for the complete catalytic oxidation of heavy liquid petroleum hydrocarbon. During the preparation, amorphous Sl2O3-SiO2 carrier is first dipped in mixed solution compounded with cerium nitrate, calcium carbonate and barium carbonate and set inside muffle furnace for heating, maintaining and cooling to treat; and the carrier is then dipped in mixed solution compounded with manganese nitrate, cobalt nitrate, nickel nitrate and copper nitrate and set inside muffle furnace for heating, maintaining and cooling to prepare the catalyst. The catalyst makes it possible to oxidize petroleum hydrocarbon completely at relatively low temperature to eliminate waste gas pollution radically, and the relatively low temperature makes the reaction controllable and practicable.

Description

Technical field [0001] The invention relates to a catalyst, which is especially suitable for the complete catalytic oxidation of wide-component liquid 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 previous research is to obtain incomplete oxidation products. Complete oxidation is not the goal pursued before. Search, related Chinese patents include: [0003] Catalyst for the oxidation of alkanes (application number 00126383.8); [0004] Method for oxidation of alkanes (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] The representative patents on catalysts for catalytic combustion of gasoline include: [0008] A gasoline cataly...
