Abstract

The invention discloses a graphene-based efficient desulfurizer for gasoline and diesel. The desulfurizer comprises raw materials in parts by weight as follows: 45-62 parts of graphene, 0.8-2.5 partsof a transition metal phthalocyanine compound, 3-4 parts of vanadium pentoxide, 2-5 parts of magnesium oxide, 1.2-2 parts of zinc oxide, 10-16 parts of polyacrylamide, 0.2-0.5 parts of tetraethylene glycol dimethyl ether, 1-2 parts of chlorophyll, 4-7 parts of folium mori, 2-4 parts of sodium hypochlorite, 6-10 parts of strong acid, 12-15 parts of activated carbon and 6-12 parts of wood flour. Bysupporting the transition metal phthalocyanine compound on graphene and adopting strong acid and sodium hypochlorite for modification, the specific surface area is increased, the adsorption activity of the surface is improved, the desulfurizer can be subjected to a reaction with sulfides under the cooperation with other components, content of the sulfides is reduced greatly, the desulfurization speed is high, and the desulfurization effect is good.

Description

technical field [0001] The invention relates to the field of desulfurization, in particular to a graphene-based high-efficiency desulfurizer for gasoline and diesel. Background technique [0002] Crude oil is unprocessed petroleum. It is a dark brown viscous oily liquid with green fluorescence and a special smell. It is a mixture of various liquid hydrocarbons such as alkanes, naphthenes, aromatic hydrocarbons and olefins. The main components of crude oil are carbon and hydrogen, accounting for 83-87% and 11-14% respectively; there are also small amounts of sulfur, oxygen, nitrogen and trace amounts of phosphorus, arsenic, potassium, sodium, calcium, magnesium, nickel, Iron, vanadium and other elements, crude oil products have a very wide range of functions and functions in social and economic development.
