Abstract

Environmental restrictions will force refineries to increase the severity in the operating conditions in order to match more stringent specifications. In the European Union, automotive fuels have to meet the so-called ultra-low sulfur (ULSD) specifications (10 ppm wt total sulfur in diesel), which are probably to be applied worldwide. In this research, production of ULSD from VACUUM GAS OIL in a pilot scale plant is investigated. To perform experiments, the catalytic bed is charged with three layers consisting of HYDROTREATING, HYDROCRACKING, and HYDROTREATING catalysts from top to the bottom, respectively. In comparison to the usual catalytic beds, third layer i.e., an excess HYDROTREATING section is added to the reactor. Results show that at the constant feed flow rate, hydrogen to hydrocarbon ratio, and pressure the yield of the HYDROCRACKING increases versus temperature, and at the start of run temperature (about 4000C) the yield of naphtha, kerosene, and diesel is about 47%. Moreover, at this temperature, the sulfur content of diesel is about 10 ppm wt. It is concluded that the HYDROGEN CONSUMPTION of the process is about 1.2 mass percent of VACUUM GAS OIL feed that is in the range of the HYDROGEN CONSUMPTION of commercial scale reactors.
