Abstract
The non-hydrogenation condensation point reducing catalyst for producing lubricating oil with heavy diesel oil, paraffin base oil, etc. is prepared by mixing molecular sieve, empholite and nitric acid in mixer fully through stirring and stoving. Compared with available hydrogenation condensation point reducing catalyst, the present invention has simple preparation process and low cost and is suitable for processing straight gasoline, high condensation point diesel oil, heavy diesel oil, paraffin base oil and other material.
Description
The present invention relates to oil product deep processing system lubricating oil non-hydrogen condensation point reducing catalysts such as a kind of heavy bavin, wax oil.
At present, in the deep processing of raw materials such as high freezing point diesel fuel, cured oil, straight-run spirit, generally be the hydrodewaxing production technique, the catalyzer of use is a Hydrodewaxing catalyst.Use the complex process of Hydrodewaxing catalyst, investment is big, the cost height.
Purpose of the present invention just is at the deficiencies in the prior art part, and a kind of production lubricating oil non-hydrogen condensation point reducing catalyst is provided.
The objective of the invention is to be achieved through the following technical solutions: this kind activity of such catalysts component is molecular sieve ZSM-5, and carrier also is a molecular sieve.Used diaspore (Al
2O
3) be binding agent.The concentration of used salpeter solution is 3-8%, and is formulated by pure nitric acid (concentration is more than 90%) and pure water, and it mainly acts on is to remove sodium ion, and acid ion is provided.Its main preparation methods is as follows:
(a) molecular sieve ZSM-54.5-6.5 part (parts by weight, down together), diaspore (Al
2O
3) 2.0-5.0 part, salpeter solution 0.5-1.5 part puts into agitator respectively and mix, and stirs full and uniform;
(b) stir after, mix again roll over block;
(c) above-mentioned block is put into the shaper barrel, extrude diameter of phi 1-5mm (preferred values is 1.6-2mm), the slice of length 30-80mm (preferable 30-40mm);
(d) above-mentioned slice is placed in the firing tray, go into stoving oven, be warming up in (1 hour preferable) at 0.5-1.5 hour 180-280 ℃ (200-250 ℃ preferable), be incubated 0.25-1 hour (half an hour is preferable), be warming up to 300-350 ℃ at 1-2 hour in (1.5 hours preferable) again, be warming up to 400-500 ℃ (450 ℃ preferable) in (half an hour is preferable) at 0.25-1 hour, be incubated 0.5-1.5 hour again (1 hour preferable), from stove, pull out;
(e) put into sintering oven again, be warming up to 500-650 ℃, be incubated 3-5 hour;
(f) after the taking-up, impurity, broken end are removed in screening again.
The optimal components ratio of above-mentioned three kinds of components is: 5 parts in molecular sieve, 4 parts in water diamond, 1 part of concentration 5% salpeter solution.
The preferred concentration of above-mentioned salpeter solution is 4-6%.
The present invention compared with prior art has following technique effect:
(1) this kind catalyzer can be suitable for straight-run spirit, high freezing point diesel fuel, heavily bavin, cured oil are raw material production non-lead gasoline for car, civilian liquefaction vapour, low freezing point diesel fuel, specialty oil products base oil, can handle lighter hydrocarbons, straight-run spirit that various crude separation go out, so it is applied widely.(2) because catalyzer uses in fixed reactor, flexible operation need not used hydrogen, so can simplify the heavy bavin of processing treatment, cured wet goods oil manufacture technology.(3) activity of such catalysts height, the octane value of product gasoline can improve 40 units (adopting the motor method test).(4) regenerability is good, and long service life can reach 1 year.(5) do not pollute the environment in preparation, the use.
The present invention is described in detail in detail below.
Being mixed with concentration with pure water and nitric acid is 5% salpeter solution.With molecular sieve ZSM-55 part, diaspore (Al
2O
3) 4 parts, 5% salpeter solution put into agitator respectively for 1 part and mix, and stir full and uniform.Mix then and roll over into irregular little pie fritter.Put into the shaper barrel with mixing the work in-process of rolling over, extruding diameter is Φ 2mm, and length is the slice of 30mm, extrudes and leaves in the Stainless Steel Disc.To put into half-finished Stainless Steel Disc and be contained on the plain trolley, push stoving oven then, in 1 hour, be warming up to 250 ℃, be incubated half an hour, in 1.5 hours, be warming up to 350 ℃ again, in half an hour, be warming up to 450 ℃, be incubated 1 hour again, from stove, pull out.The work in-process of oven dry are put into the baking freezing of a furnace, are warming up to 650 ℃, be incubated 3-5 hour, open fire door.Behind the sintering, through screening, remove impurity, broken end again.All the other finished product packing warehouse-ins.
0.5 part in 4.5 parts in molecular sieve, 2.0 parts of diaspores, 8% nitric acid liquid put into agitator respectively mix, stirs full and uniformly, also can reach effect of the present invention by the catalyzer of above-mentioned steps making.
With 6.5 parts in molecular sieve, 5.0 parts of diaspores, 1.5 parts of mixing of 3% nitric acid liquid, by the above-mentioned steps operation, the catalyzer of making can reach effect of the present invention.
With 4.5 parts in molecular sieve, 4.0 parts of diaspores, 1.2 parts of mixing of 5% nitric acid liquid, by the above-mentioned steps operation, the catalyzer of making can reach effect of the present invention.
With 5.0 parts in molecular sieve, 2.0 parts of diaspores, 0.8 part of mixing of 6% nitric acid liquid, by the above-mentioned steps operation, the catalyzer of making also can reach invention effect of the present invention.
