| titleOfInvention | Method for hydrotreatment of gas-oil fractions using catalyst based on amorphous mesoporous aluminium oxide having high coherence of structure |
| abstract | FIELD: chemistry. n SUBSTANCE: present invention relates to hydrotreatment of hydrocarbon raw material of gas oil type. Described is a method for hydrotreatment of at least a gas-oil fraction having a weighted average temperature (TMP) in range from 240 to 350 °C, wherein method is carried out at temperature in range from 250 to 400 °C, at total pressure in range from 2 to 10 MPa, at ratio of volume of hydrogen and volume of hydrocarbon raw material in range from 100 to 800 litres per litre and at hour volume rate (VVH), defined as ratio of volumetric flow rate of liquid hydrocarbon material to volume of catalyst loaded into reactor in range from 1 to 10 h -1 , wherein method uses at least one catalyst containing at least one metal from group VIB and / or at least one metal from group VIII of periodic table of elements and a carrier containing amorphous mesoporous aluminium oxide, wherein said aluminium oxide is obtained by carrying out at least, the following stages: a) at least one first step of depositing aluminium oxide in the aqueous reaction mixture based on at least one basic precursor selected from sodium aluminate, potassium aluminate, ammonia, sodium hydroxide and potassium hydroxide, and at least one acid precursor selected from aluminium sulphate, aluminium chloride, aluminium nitrate, sulphuric acid, hydrochloric acid and nitric acid, a step for heating the suspension obtained after step a) between step a) and second step a') of deposition, which is carried out at a temperature in range of 20 to 90 °C for period of 7 to 45 minutes; a') a second deposition step, which is carried out between the first deposition step a) and the heat treatment step b), b) a step for thermal treatment of the suspension obtained after step a) at a temperature in range of 50 to 200 °C for period of 30 minutes to 5 hours, which enables to obtain an aluminium oxide gel; c) a step for filtering the suspension obtained after step b) of heat treatment, followed by performing at least one step of washing the obtained gel; d) drying aluminium oxide gel obtained after step c) to obtain powder; e) a step for forming a powder obtained after step d) to obtain a raw material; f) a step for thermal treatment of raw material obtained after step e) at a temperature in range from 500 to 1000 °C, optionally in an air current containing up to 60 vol. % of water. n EFFECT: technical result is the development of a method for hydrotreatment of at least a gas-oil fraction, in which a catalyst is used, having improved catalytic characteristics, wherein said method provides high hydrodesulphurisation activity. n 14 cl, 5 ex, 6 tbl |
