It is known that when hydrotreating heavy crude oil, the addition of lighter fractions provides a higher degree of sulfur removal. The aim of this work is to study the quality of the hydrogenate mixed with the gasoline fraction when hydrotreating light atmospheric gas oil. Hydrotreating was carried out using a flow-through laboratory unit on an aluminum-cobalt-molybdenum catalyst. The total sulfur content was analyzed according to ASTM D4294 method, saturated and aromatic hydrocarbons were determined by the liquid adsorption chromatography on the silica gel. The paper describes the influence of the technological parameters such as temperature and feed space velocity (FSV) on the degree of sulfur removal from the light atmospheric gas oil. As a result, the optimal parameters of the process are T=340°C and FSV = 2 h-1. The paper shows the influence of the feedstock composition, the degree of the gasoline fraction involvement, on the chemical composition and quality parameters of the products. It is found that the hydrotreating depth of the light atmospheric gas oil increases with the addition of 5% gasoline fraction. When hydrotreating atmospheric gas oil mixed with the gasoline fraction, compared with the initial atmospheric gas oil hydrotreating, the degree of sulfur removal grows by 2%. The content of aromatic hydrocarbons in the hydrogenate decreases, and saturated hydrocarbons - increases. [ABSTRACT FROM AUTHOR] |
