preparation example Construction

[0039] One, the preparation steps of catalyst carrier are:

[0040] 1. Raw materials are pre-mixed, and pseudo-boehmite, solid aluminum sol, and activated α-alumina powder are mixed according to the net weight ratio of 70-90:30-5:0-10, and 1-20% of the weight of the bond is added Put the agent and 1%~30% pore expander into the mixer, dry mix for 10~60 minutes, take out the powder and pass it through the 20~60 mesh screen to remove the coarse particles;

[0041] 2. Preparation of mud-making solution: based on the total weight of the powder in step 1, weigh 0.5-10% of phosphoric acid and acetic acid by weight and dissolve them in deionized water with 60-150% of the total weight of the powder;

[0042] 3. Put the powder into the mud-making machine, add the mud-making solution obtained in step 2, and seal the mixture for 5 to 30 minutes to make the powder into mud;

[0043] 4. Send the mud material obtained in step 3 into the mud refining machine, and train the mud material into ...

Embodiment 1

[0052] a. Put 5.9kg of pseudo-boehmite, 3.6kg of solid alumina sol, 0.5kg of activated α-alumina powder, 0.2kg of safflower gum, and 2kg of starch into the conical mixer, take it out and put it into the mixer after 15 minutes of mixing inside the clay machine;

[0053] b. Then dissolve 0.5kg of citric acid monohydrate, 0.32kg of phosphoric acid, and 0.2kg of acetic acid in 8.8kg of deionized water, and finally add the aqueous solution into the mud making machine by spraying, and make mud for 8 minutes. After the mud becomes a block take out;

[0054] c. Load metal on the catalyst carrier obtained in step b: Dissolve 40 grams of metal salts ammonium metatungstate, ammonium heptamolybdate, cobalt nitrate hexahydrate, nickel nitrate hexahydrate and phosphoric acid in 105 grams of water, without precipitation and with After a long period of stability, the catalyst carrier is fully impregnated in the metal solution and then dried and roasted. The conditions for drying and roasting...

Embodiment 2

[0058] a. Put 6.7kg of pseudo-boehmite, 2.8kg of solid aluminum sol, 0.5kg of active α-alumina powder, 0.2kg of safflower gum, and 2kg of starch into the conical mixer, take it out and put it into the conical mixer after 15 minutes of mixing inside the clay machine;

[0059] b. Then dissolve 0.5kg of citric acid monohydrate, 0.5kg of phosphoric acid, and 0.35kg of acetic acid in 8.8kg of deionized water, and finally add the aqueous solution into the mud making machine by spraying, and make mud for 8 minutes. After the mud becomes a block take out;

[0060] c. Load metal on the carrier obtained in step b: Dissolve 40 grams of metal salt and phosphoric acid in 105 grams of water. After no precipitation and long-term stability, the carrier is fully immersed in the metal solution and then dried and The conditions of roasting, drying and roasting are as follows: drying in an oven at 55°C for 13 hours, and roasting in an oxidizing atmosphere at a temperature of 750°C for 7 hours; ...

Abstract

The invention discloses a method for producing high quality light white oil from base oil. The method comprises the following steps: the raw material base oil is heated to reaction temperature and fully mixed with hydrogen, and then enters a hydrogenation reactor loaded with a catalyst I for hydrofining under the action of the hydrofining catalyst I to remove most of S, N, and aromatic impuritiesin the raw material base oil; reacted products enter into two series reactors respectively loaded with a catalyst II and a catalyst III for contact with the catalyst II and the catalyst III to removethe S and perform dearomatization saturated reaction; obtained reactants are subjected to gas-liquid separation by a high-pressure separator and a low-pressure separator and then enter a fractionationsystem for fine cutting to obtain a variety of different grades of high-quality light white oil products. The method can produce the high-quality light white oil with good quality, high yield, shortdistillation range, high purity, low sulfur and low aromatics.

Description

technical field [0001] The invention belongs to the field of petrochemical technology, in particular to a method for producing high-quality light white oil from base oil. Background technique [0002] White oil is a type of petroleum product obtained by deep refining of lubricating oil fractions to remove impurities such as aromatics and sulfides in lubricating oil fractions. It is colorless, tasteless, odorless, chemically inert and has excellent light and heat stability. It is widely used in chemical industry, daily necessities, food, medicine, textile and agriculture and other fields. According to different uses and refining depths, white oil can be divided into industrial grade, cosmetic grade, food grade and pharmaceutical grade. Among them, food-grade white oil has the deepest degree of refinement and the strictest quality requirements. [0003] The traditional process uses acid treatment and white clay refining method to produce white oil. Not only the yield of whit...
