Definitions
- Base oils with very high viscosity indices can be obtained by hydrocracking vacuum gas oils.
- Components with low VI are either split into low-boiling components or converted into compounds with high VI by hydrogenation, ring cleavage and isomerization.
- the subsequent dewaxing serves to improve the fluidity at low temperatures.
- long-chain, unbranched and little branched hydrocarbons are separated. This separation can take place physically by precipitating the paraffin crystals at low temperatures using a mixture of solvents or by hydrogenating cleavage of these compounds on shape-selective catalysts.
- To assess fluidity e.g. the determination of the pour point according to DIN 51 597 is used.
- DE-PS 2 613 877 relates to a process for the production of lubricating oil in which lubricating oils with a low pour point and a VI of 95 are obtained via two hydrocracking stages and a catalytic dewaxing stage.
- the viscosity index of the base oil obtained in all these processes is not sufficient to produce high-quality lubricating oils from these base oils.
- This object was achieved with a two-stage process for the production of oxidation-stable base oils with a VI (viscosity index) 110 to 135 (VHVI oils) and very good fluidity at low temperature by using matt heavy mineral oil fractions with a boiling range above 350 ° C on a hydrocracking catalyst converted under hydrocracking conditions to 20 to 80% by weight into fractions which boil below 360 ° C, the reactor discharge, if appropriate, separated into liquid and gas phase in a high-pressure separator, the entire reactor discharge or only the liquid phase, directly or after distillation of the below 360 ° C boiling fractions in a second stage treated with hydrogen in the presence of a catalyst at 200 to 450 ° C and 20 to 150 bar, which is a crystalline borosilicate zeolite of the pentasil type, aluminum oxide and / or amorphous aluminosilicate as support material and one or more metals from group VIb and / or group VIII of the periodic table and Phos contains phor, and after distillation
- the first stage is usually carried out at pressures of 40 to 150 bar, temperatures of 300 to 450 ° C and specific catalyst loads of 0.1 to 4 kg / lxh with hydrogen in the presence of a catalyst, the support of which is preferably made of aluminum oxide, a amorphous aluminosilicate and / or a dealuminated Y zeolite, and which contains as hydrogenation components one or more metals from group VI b and / or VIII of the periodic table and phosphorus.
- the entire liquid outflow from the first stage is fed directly to the second stage without intermediate relaxation or after the parts boiling below 360 ° C have been distilled off, with printing of e.g. 20 to 150 bar, temperatures of e.g.
- middle distillates obtained in this process have excellent cooling properties with a boiling range of 180 to 360 ° C.
- the pour point is always below -30 ° C.
- Such middle distillates are valuable blending components for the production of low-temperature diesel fuels.
- the preparation of catalysts for the hydrocracking stage of the process according to the invention can be carried out by mixing an aluminum oxide component with a silicon oxide component or an aluminosilicate, optionally with the addition of a dealuminated zeolite of the Y type with an SiO2 / Al2O3 molar ratio in the range from 7 to 150 and a peptizing agent, such as for example formic acid.
- a SiO2 component a hydrogel with an SiO2 content of 10 to 20% by weight is particularly suitable Bands in the IR spectrum at wavenumbers of 1 630 and 960 cm ⁇ 1, a Na content of less than 0.01% by weight and a BET surface area of more than 400 m2 / g.
- Suitable feedstocks for the process are heavy gas oils, vacuum gas oils, deasphalted residue oils and mixtures thereof in the boiling range above 350 ° C. A prior breakdown of the organic sulfur and nitrogen compounds is not necessary, but is advantageous in certain cases.
- the base oils obtained by the process according to the invention respond much better to pour point improvers than, for example, base oils dewaxed with solvents. It won't just be smaller amounts of pour point improver are required to set a given pour point, but also lower pour points than were possible using conventional methods.
- the middle distillates in the boiling range 180 to 360 ° C are only separated after the dewaxing stage, this results in excellent cold properties for these middle distillates.
- the distillates With a pour point of ⁇ -30 ° C, the distillates also meet extreme requirements, e.g. for diesel fuel in winter operation.
- a moist carrier mixture is prepared by mixing 227 g of hydrogel (SiO2 content 15%) with 102 g of aluminum oxide and 10 g of formic acid, adding 18 g of phosphoric acid, 16.2 g of nickel nitrate and 309 g of ammonium heptamolybdate dissolved in 150 ml of water.
- the carrier mixture is extruded through a 1.5 mm die, then dried at 150 ° C. and calcined at 500 ° C. for 5 hours.
- the moldings are impregnated with a solution consisting of nickel nitrate and ammonium heptamolybdate and dried and calcined again.
- the finished catalyst has the following composition (wt .-%): Al2O3 51, SiO2 17, MoO3 18, NiO 5, [PO4] 3 ⁇ 9.
- borosilicate zeolite A borosilicate zeolite of the pentasil type is in a hydrothermal synthesis from 640 g of highly disperse SiO2, 122 g of H3BO3, 8000 g of an aqueous 1,6-hexanediamine solution (mixture 50:50 wt .-%) at 170 ° C under autogenous pressure in a stirred autoclave without added alkali. After filtering off and washing out, the crystalline reaction product is dried at 100 ° C./24 h and calcined at 500 ° C./24 h.
- This borosilicate zeolite is composed of 94.2 wt .-% SiO2 and 2.3 wt .-% B2O3 (loss on ignition: 3.5 wt .-%).
- the catalyst was prepared as described in Example 1 with the addition of the borosilicate zeolite.
- a vacuum gas oil from Amna / Sahara with the following properties was used for the example given here:
- the gaseous constituents were separated off in a high-pressure separator and the entire liquid portions were fed to the dewaxing stage.
