Реферат: Nowadays the refining industry has a smooth pass to the production of gasoline that meets European quality standard Euro-5. According to this standard, sulfur content in gasoline has to be less than 10 ppm. One of the main challenges facing the production of commercial gaso-line is hydrotreating of catalytic cracking gasoline. FCC gasoline is one of the main compo-nents of blending gasoline. It is characterized by high sulfur content (150-3500 ppm) and high octane number (92-93 points) [1]. Hydrotreating of full FCC gasoline fraction results in inevi-table octane number loss because of the hydrogenation of unsaturated high-octane com-pounds. Maximum permissible octane number loss after hydrotreating has not to exceed 1,5 point. Otherwise hydrotreating FCC gasoline is ineligible for production of commercial gaso-line with octane number more than 95. There are many industrial processes for selective FCC gasoline hydrotreating. These processes are based on previous rectification of full fraction to light (with high olefin content) and heavy (high sulfur content) fractions followed by separate hydrotreating and blending [2]. However such processes are technologically complicated and require more energy consumptions. Alternative way is the developing of selective hydrotreating catalyst of full FCC gasoline fraction. It permits the process to be carried out on the available equipment. Currently there is no method of selective hydrotreating catalysts for hydrotreating of full FCC gasoline fraction that provides to obtain gasoline with sulfur content less than 10 ppm with octane loss less than 1,5 point. In this paper we propose a method for the synthesis of selective hydrotreating catalyst for en-tire FCC gasoline fraction. The method is based on the use of amorphous aluminosilicate as a carrier. The catalyst provides the production of gasoline containing less than 10 ppm of sulfur with minimum octane loss (<1,5 point).
