Normal-temperature desulfurizer for oils and preparation method thereof

The invention relates to a normal-temperature desulfurizer for oils and a preparation method thereof, which solve the problem that the prior normal-temperature desulfurizer has relatively low precision and sulfur capacity. The normal-temperature desulfurizer for the oils mainly comprises the following components in percentage by weight: 15 to 25 percent of mixed powder of a copper oxide and a zinc oxide, 40 to 55 percent of iron trioxide, 5 to 20 percent of activated zinc oxide, 5 to 15 percent of aluminum oxide, 3 to 5 percent of carboxymethyl cellulose and 15 to 25 percent of diatomite. Thedesulfurizer is prepared by mixing the metal oxides, adding the mixture into an aqueous solution of potassium hydroxide, stirring and mixing the mixture, extruding the mixture to shape and drying andbaking the extruded mixture.
