Abstract

The invention belongs to the technical field of adsorptive desulfurization and particularly relates to a selective fuel oil desulfurization adsorbent. The selective fuel oil desulfurization adsorbentis prepared from raw materials in parts by mass as follows: 1-3 parts of copper chloride, 3-5 parts of iron ions, 100-150 parts of graphene powder, 10-12 parts of potassium permanganate and 50-80 parts of an ethanol solution. The selective fuel oil desulfurization adsorbent has the benefits as follows: the selective fuel oil desulfurization adsorbent performs adsorptive removal on thiophene and derivatives thereof and benzothiophene, adsorption experiment detection proves that the adsorbent has higher adsorptive removal capability for thiophene-type sulfides in gasoline, is lower in cost, produces no pollutants in the adsorption process, has good economic practicability and meets the environmental protection requirement.

Description

technical field [0001] The invention belongs to the technical field of adsorption desulfurization, and in particular relates to a selective fuel oil desulfurization adsorbent. Background technique [0002] The sulfides in fuel oil exist in the form of hydrogen sulfide, mercaptan, sulfide, disulfide, thiophene, disulfide, benzothiophene and its derivatives. These sulfur compounds will not only lead to poor oxidation stability of fuel oil, lower octane number and corrosion of engine combustion system, but also the sulfur oxides generated after combustion are the main pollutants of air pollution. Sulfur-containing compounds in fuel oil are burned to generate sulfur oxides (SOx), which are emitted into the atmosphere and cause acid rain, thereby causing serious pollution to the environment. In addition, the acidic substances produced when these oxides meet with water will corrode the engine and crankcase components. More importantly, SOx is an inhibitor of automobile exhaust g...
