Abstract

This paper examines options for reducing emissions by improving fuel quality. In the scope, the importance of deep hydrodesulphurization and hydrodenitrogenation is discussed which reduce the formation of acid :rains and sulphate particles. The experimental results of the hydrotreating of a gas oil on Ni-Mo/A}zO.;fpromoter catalyst are presented. The effect of the key process parameters (temperature, pressure, LHSV, hydrogen/hydrocarbon volume ratio) on the yield and quality of products are discussed. Based on experimental results, the advantageous process parameters were determined for producing diesel fuel blending components of 500, 400, 300, 200, 150 and 50 ppm sulphur content. The possible applications of the obtained diesel fuel blending components in themselves or together with others are examined to satisfy the standard specifications of commercial products.
