Problems solved by technology

[0005] The production methods of Vaseline in the prior art all adopt the production process of blending the raw materials first and then refining them. The disadvantage is that it is not convenient to flexibly produce a series of products with different consistency, and it is not possible to adopt targeted refining conditions for different raw materials. The purpose of the invention is to solve the above problems and propose a flexible production method that can obtain vaseline products of various consistency

Embodiment Construction

[0009] The method of the present invention adopts vacuum distillate oil base oil and vacuum residue light dewaxing paste as raw materials, and selects hydrofinishing method for processing, and the two raw materials can adopt the same hydrofinishing catalyst, under the same or different operating conditions Hydrofining is carried out. Hydrofining adopts fixed bed two-stage refining process. The same or different catalysts can be used in the two stages. It is recommended to use the same catalyst and fill the two stages of beds with equal volumes. The hydrofining catalyst uses alumina or alumina-silicon oxide as the carrier component, and the metals of Group VIB and Group VIII in the periodic table of elements as active components, especially tungsten and nickel, and its active component content is WO 3 25% ~ 35%, NiO2% ~ 8%, specific surface area ≥ 160m 2 / g, pore volume ≥ 0.3ml / g. Better for WO 3 29.5%~31.5%, NiO 4%~5%, specific surface area 200~240m 2 / g, pore volume 0.4...

Abstract

The present invention belongs to the field of vaseline product refining and blending technology. In the production process, the oil component and the cerate component in vaseline material are first refined separately, especially hydrorefined, and the refined components are then blended in different proportions to produce serial vaseline products of required degree of consistency. The present invention can produce various vaseline products in required degree of consistency for the need of medicine and cosmetics.

Description

technical field [0001] The invention relates to a method for producing vaseline, in particular to a flexible production method capable of obtaining vaseline products of various thicknesses, and the method of the invention belongs to the technical field of production of vaseline products. Background technique [0002] Vaseline is an ointment-like petroleum product with certain properties. The conventional vaseline production process is to first 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 raw materials. Traditional Vaseline blending components are vacuum distillate base oil and vacuum residue light dewaxing paste. The traditional vaseline refining methods are acid-clay method and aluminum chloride method. These two methods all have disadvantages such as poor...
