Abstract

The invention provides a coal tar filtering aid. A preparation method of the coal tar filtering aid comprises the following steps: S1, preparing raw materials: (1) preparing organic acid, inorganic acid, salt, a precipitator, a metal complex, a polymeric flocculant, alcohols, a filter aid and desalted water; and S2, a preparation process: (1) pouring the organic acid prepared in the step S1 into a glass container filled with water, then pouring the inorganic acid prepared in the step S1 into the glass container, and then mixing and stirring for 10-15 minutes under the assistance of ultrasonic waves in an environment with the temperature of 20-30 DEG C. The coal tar filtering aid provided by the invention is a filtering aid SF-01 prepared from organic acid, inorganic acid, salt, a precipitator, a metal complex, a polymeric flocculant, alcohols, a filter aid and desalted water in proportion, and has the advantage of high metal removal rate.

Description

technical field [0001] The invention belongs to the technical field of coal tar filter aids, in particular to a coal tar filter aid. Background technique [0002] Coal tar is a black or brown viscous liquid with an odor similar to naphthalene or aromatic hydrocarbons. It is a by-product of dry distillation of coal to produce coke and gas. The composition is complex, mainly a mixture of phenols, aromatic hydrocarbons and heterocyclic compounds. With coal tar hydrogenation units being put into operation one after another, the metal content in coal tar has become an important factor affecting the start-up cycle of the coal tar hydrogenation industry. In related technologies, a coal tar dehydration method and a coal tar dehydration device are disclosed, which belong to the coal tar Dehydration technology field. The coal tar dehydration method of the present invention includes: preheating the crude coal tar to 80-90°C, and then performing membrane separation; the membrane sepa...
