Embodiment Construction

[0028] The modified β molecular sieve in the β molecular sieve-containing catalyst used in the process of the present invention is obtained by a new synthetic modification method, and the main steps of modification include:

[0029] (1) The beta molecular sieve slurry after crystallization is directly subjected to ammonium exchange, filtration, washing, drying and roasting;

[0030] (2) The β molecular sieve after roasting and deammonification carries out acid treatment;

[0031] (3) The acid-treated β molecular sieve is subjected to hydrothermal treatment.

[0032] The above crystallized β molecular sieve is generally synthesized by using organic ammonium (such as tetraethylammonium hydroxide) as a template by hydrothermal crystallization. Its SiO 2 / Al 2 o 3 The weight ratio is generally 25-30, Na 2 The content of O is 3.0wt%-4.0wt%. The crystallized β molecular sieve slurry is directly exchanged with ammonium salt, the concentration of ammonium salt in the slurry is 0...

Abstract

The invention discloses a production method of vaseline. The method comprises the following steps: 1, blending HVI650 cerate, reduced pressure distillate oil base oil and selective reduced pressure residual oil light removal cerate which are treated as raw materials; 2, hydrotreating the obtained blended mixture through first-stage series hydrofinishing with a fixed bed; and 3, allowing the blended mixture to go through a first reactor and a second reactor under hydrofinishing conditions, wherein the first reactor is filled with a hydroisomerizing catalyst and a hydrofinishing catalyst, and the second reactor is filled with a hydrofinishing catalyst. The method of the invention allows high quality vaseline products to be obtained by treating raw materials which cannot be vaseline raw materials in the prior art as the vaseline raw materials, blending the raw materials with a proper process and hydrogenating the raw materials, so the vaseline raw material source is enlarged, the HVI650 cerate utilization approach is widened, and economic benefits are improved.

Description

technical field [0001] The invention relates to a method for producing petrolatum, in particular to a production method which can expand the source of petrolatum raw materials and obtain high-quality petrolatum products. Background technique [0002] Vaseline is an ointment-like petroleum product with certain properties. The conventional vaseline production process is to firstly blend the raw materials to make the physical properties of the blend meet the product requirements; then refine the blend to remove non-ideal chemical components such as sulfur, nitrogen, oxygen and condensed ring aromatics contained in the blend . [0003] The traditional vaseline blending components are vacuum distillate oil base oil and vacuum residue light dewaxing paste. The base oil can be flexibly used in various brands and varieties, while the light dewaxing paste has few varieties and low output, thus The raw material source of petroleum jelly is limited. [0004] CN1061678C introduces a ...
