Shortcoming existing for preceding slurry fouling inhibitor is complicated components, and synergistic effect and intermiscibility be not good enough between component, causes antisludging agent
Additive amount is big, at high cost with agent, and using effect is not easy to hold.Component is provided and constitutes simple, the good oil of synergistic effect between component
Slurry antisludging agent can avoid these disadvantages.
Summary of the invention
In view of the above-mentioned deficiencies in the prior art, it is an object of the present invention to provide, a kind of component is simple, synergistic effect is good between component
FCC Slurry Antifoulant and preparation method thereof.
A kind of catalytic cracked oil pulp slurry fouling inhibitor provided by the invention includes following components:
Magnesia colloidal solution, polyisobutene succinimide, solvent, wherein magnesia colloidal solution and polyisobutene succinyl
The weight ratio of imines is 1: 0.1~0.5, and the weight ratio of magnesia colloidal solution and solvent is 1: 0.1~1.0.
The magnesia colloidal solution contains the magnesia of 15~45% (mass fractions).
The magnesia colloidal solution is by magnesium hydroxide, aphthenic acids or fatty acid, high boiling fraction oil 100~350
It is DEG C reacted to be made.
Its oily initial boiling point >=300 DEG C of the high boiling fraction.
The base number of the polyisobutene succinimide be 15.0~30.0 mgKOH/g, nitrogen content be 1.20~
1.40% (mass fraction), 100 DEG C of viscosity are 130.0~180.0 mm2/s 。
The solvent is initial boiling point >=180 DEG C, the aromatic solvent naphtha of the end point of distillation≤300 DEG C.
The preparation method of a kind of FCC Slurry Antifoulant provided by the invention, comprising the following steps: diluted with solvent
Polyisobutene succinimide is added it under agitated conditions in magnesia colloidal solution, is uniformly mixed, quiescent settling 24
Hour, with obtaining slurry fouling inhibitor after 50 mesh net filtrations.
Specific embodiment
Below by specific embodiment, the present invention is described in further detail.
Scale inhibition performance evaluation method:
