Lubricating oil with low condensing point

Номер: CN104342232A
Автор: HAN PENG, SHANG WEIZHI, SUN LIBIN
Принадлежит:

The invention provides a lubricating oil with low condensing point, which solves the problem of poor fluidity of the current lubricating oils under low temperature condition. The lubricating oil comprises 80-90 parts of base oil and 10-15 parts of functional additive. The functional additive is a pour-point depressant, an anti-grinding agent and a clearing agent, the pour-point depressant employs polymethyl acrylate, alkane chain length of polymethyl acrylate is 10-18, and polymethyl acrylate has good effect to viscosity-reducing effect of the lubricating oil and has good low temperature fluidity, the added anti-grinding agent and the clearing agent in the lubricating oil have good anticorrosion performance and antiwear performance to parts in the using machines.

Lubricating oil hydrodewaxing production technology

Номер: CN104342206A
Автор: HAN PENG, SHANG WEIZHI, SUN LIBIN
Принадлежит:

The invention provides a lubricating oil hydrodewaxing production technology, which solves the problem of low yield in a lubricating oil production technology in prior art, and the lubricating oil hydrodewaxing production technology comprises the following steps: 1)heating raw oil through pressure reduction by a heating furnace, introducing into a reactor, performing a catalytic reaction and then introducing into a normal pressure fractionate tower, introducing the normal pressure oil through fractionation at normal pressure in a hydrogenation depickling reactor; 2)introducing the deacidified oil product into a furfural treating tower, introducing the fully reacted furfural refining oil in a hydrodewaxing reactor for hydrodewaxing; and 3)introduced hydrodewaxed oil in a hydrogenation supplement refining reactor which is connected to the hydrodewaxing reactor in series for blending the finished product lubricating oil. The method employs a technical flow of hydrogenation and deacidification ...
