Abstract

The invention relates to a target anchorage agent for sulfide in oil and a preparation method and application thereof. The preparation method of the target anchorage agent for sulfide comprises the following steps of loading precursor-metal ion of the anchorage agent for the sulfide on the surface of magnetic nanoparticle coated by a silicon dioxide shell layer through an impregnating method, obtaining a stable magnetic nanoparticle-metal nanocluster complex structure through roasting and preparing to obtain the target anchorage agent for the sulfide. The magnetic nanoparticle is utilized as a target agent, metal nanocluster is utilized as an anchorage agent for the sulfide, and a magnetic nanoparticle-metal nanocluster complex structure is constructed. The target anchorage agent not only avoids reducing oil octane value, but also reduces energy consumption; thus, clean low-sulfur oil can be obtained, vehicle emission level can be reduced, environmental air quality is improved, and the target anchorage agent has a very good application prospect.

Description

technical field [0001] The invention relates to a targeting anchoring agent for sulfide in oil products and a preparation method and application thereof, belonging to the field of fine petrochemical industry. Background technique [0002] In recent years, my country's smog weather has become more and more serious, and the exhaust gas emitted by automobiles fueled by gasoline is one of the important factors that aggravate environmental pollution. With the improvement of people's awareness of environmental protection and the increasingly strict sulfur content of vehicle fuel indicators, the production of clean low-sulfur hydrocarbon fuels has become a new challenge and research focus for the oil refining industry. In order to reduce the emission level of motor vehicles and improve the ambient air quality, the Ministry of Environmental Protection of the People's Republic of China currently states that the National Sixth Standard will be formulated and released by the end of 201...
