▎ 摘　　要

NOVELTY - Adsorption desulfurization catalyst, comprises graphene oxide and mono-disperse transition metal oxide. The graphene oxide includes an edge region and a conjugated region. The edge region has a carboxy group. The conjugated region has a hydroxy group and an epoxy group. At least part of the carboxy of the edge region of the graphene oxide is converted into an amide group. At least part of the conjugated region hydroxy of the graphene oxide is converted into carbamate. The mono-disperse transition metal oxide is embedded between the graphene oxide layers. USE - Used as an adsorption desulfurization catalyst. ADVANTAGE - The catalyst has an effect of rapidly adsorbing various sulfur-containing impurities in gasoline, and can remove the adsorbed impurities. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for preparing adsorption desulfurization catalyst, comprising (1) mixing the graphene oxide and isocyanate according to mass ratio of 1:3-1:5, under the protection state of inert gas, performing ultrasonic microwave reaction, and then filtering, washing and drying to obtain the pre-treated graphene oxide; and (2) dispersing the pre-treated graphene oxide in the transition metal salt solution, adjusting pH to alkaline, stirring and reacting, allowing to stand for aging, filtering, washing and drying, and then baking at low temperature below 120 degrees C to obtain the product.
