Abstract

The invention relates to a preparation method of a catalyst for improving the performance of gasoline hydrogenation modification. The MoCoNi / EMT-FAU / SBA-15 catalyst prepared by the present invention not only has a higher reactive site density, a stable alloy nanoparticle active component, but also has an open pore structure, which is beneficial to the sulfur-containing FCC gasoline in the catalyst On the other hand, the dispersion of active metals in the catalyst can be ensured by the method of equal-volume fractional metal impregnation and citric acid modification. The particle length is beneficial to the improvement of hydrodesulfurization performance. The obtained hierarchical porous molecular sieve composite catalyst has a high hydrodesulfurization rate, and maintains the octane number of FCC gasoline to the greatest extent, showing excellent hydromodification performance.

Description

technical field [0001] The invention relates to the field of petrochemical catalysis, in particular to an FCC gasoline hydrogenation desulfurization hydrogenation upgrading catalyst and a preparation method thereof. Background technique [0002] With the increasingly stringent automotive gasoline standards and environmental protection regulations, countries around the world have adopted different measures to improve the quality of gasoline products. The general trend is deep desulfurization, olefin reduction and aromatics content control to produce clean gasoline with low sulfur and olefins. my country's motor gasoline mainly comes from FCC gasoline, which is characterized by high sulfur and high olefins. The sulfur oxides generated by the high-temperature combustion of sulfur in gasoline not only pollute the environment, but also increase CO and NOx emissions. Olefin is an unstable factor in gasoline, which is easy to form colloid and is the main source of carbon deposit. ...
