Embodiment 1-6

[0017] The adsorption refining agent was added according to the addition ratio specified in Table 2. The type of raw oil and the test results are listed in Table 1. After the raw oil passes through the outlet of the electro-refinement settling tank, it is mixed and stirred with the adsorption refining agent at 85°C for 30 minutes, and filtered to obtain the refined oil. The raw material base nitrogen is base oil base nitrogen before complex denitrification.

Abstract

This invention relates to an adsorption-refinery agent for solvent refinery of base oil for lubricating oil. The adsorption-refinery agent is mainly composed of porous substances such as aluminum oxide and silicon oxide, and has a network skeleton crystal structure (an Al- octahedron layer sandwiched in two Si-O tetrahedron layers), and a defect structure caused by solvent modification. The adsorption-refinery agent, when used after refinery and denitrogenation of base oil, can effectively remove residual nitrogen in base oil, thus can increase the oil yield and filtration efficiency, and lower the filtration temperature.

Description

technical field [0001] The invention belongs to the field of petroleum refining, and relates to an adsorption refining preparation used in the solvent refining of lubricating oil base oil, which can be used after the liquid-phase complexation denitrification process, and can effectively absorb the denitrification residue to play the role of adsorption, auxiliary It has the advantages of small dosage, low application temperature and less waste residue discharge. Background technique [0002] At present, liquid-phase complexation denitrification process is generally used in the refining of lubricating oil base oils in various refineries in my country to remove non-ideal components such as basic nitrogen compounds in lubricating oil base oils. Although the denitrified oil passes through the electro-sedimentation separation tank, most of the complexes are separated. However, some complexes remain in the oil and must be removed. The currently adopted method is to use 1-2% white...
