Abstract
The invention discloses a magnetic catalyst carrier preparation method. Ferrous chloride tetrahydrate and iron chloride hexahydrate are dissolved in a stainless steel container according to a certain ratio and are heated up to 100 DEG C under protection of nitrogen, and aqueous ammonia is added to deposit ferroferric oxide particles. Appropriate oleic acid is slowly dropped in, a magnet is used for separating, and then deionized water is used for repeatedly washing to obtain black block-shaped magnetic ferroferric oxide gel. The black block-shaped magnetic ferroferric oxide gel is dispersed into n-hexane to form uniform n-hexane alky magnetic solution. Activated carbon is immersed into magnetic dipping solution, and the magnetic dipping solution is absorbed and then is put into a vacuum drying box for conducting negative pressure dipping. After dipping is finished, the activation carbon is filtered out from the dipping solution, products are washed through the n-hexane in an ultrasonic mode to remove unstable magnetic components on the surfaces of the products and the insides of the products, and the products are dried under the temperature of 60 DEG C. Under protection of the nitrogen, the dipping products are sintered to form magnetic activation carbon products.
Description
Technical field
The invention belongs to chemical technology field, more specifically say a kind of technology of preparing about magnetic catalyst carrier.
Background technology
There is the magnetic active carbon preparation method of report to have so concentrated.Active carbon is immersed in the salting liquid of iron content, cobalt, nickel, then immerses in ammonium oxalate solution, pass into H again under 600～1200 ℃ at last
2And N
2, magnetize processing; Adopt Soaking synthesizing magnetic cocoanut active charcoal.In addition, absorption method is also a kind of straightforward procedure of preparation magnetic active carbon, and the magnetic polymer microsphere charing method is also one of important method of preparation magnetic active carbon microparticle.
Summary of the invention
The objective of the invention is to overcome the defective of prior art, a kind of new magnetic active carbon catalyst carrier technology of preparing is provided, utilize the present technique method to adopt the standby magnetic active carbon of negative pressure impregnation legal system, not only simplified the preparation technology of magnetic active carbon, and the active carbon magnetic of producing is stronger.
The present invention is achieved by the following technical solutions: frerrous chloride and iron chloride are dissolved in rustless steel container according to a certain percentage, are warming up to 100 ℃ under the protection of nitrogen, add ammoniacal liquor in the high-speed stirred process, deposit ferriferrous oxide particles.After precipitation finishes, slowly drip appropriate oleic acid in solution, and be incubated 40 minutes, after separating with magnet, repeatedly clean through deionized water, obtain the block magnetic ferroferric oxide gel of black.The block magnetic ferroferric oxide gel of black is distributed to forms uniform n-hexane base magnetic solution in n-hexane.Active carbon is immersed in the magnetic dipping solution, puts into vacuum drying chamber after absorption, carry out negative pressure impregnation.Dipping leaches active carbon after finishing from dipping solution, product n-hexane supersound washing is removed its surface and inner unsettled magnetic component, and dried at 60 ℃ of temperature.At last, impregnation product sintering under nitrogen protection is formed the magnetic active carbon product.
The specific embodiment
The preparation of magnetic liquid.Frerrous chloride and the iron chloride ratio according to 3:1 is dissolved in rustless steel container, is warming up to 100 ℃ under the protection of nitrogen, add ammoniacal liquor in the high-speed stirred process, deposit ferriferrous oxide particles.After precipitation finishes, slowly drip appropriate oleic acid in solution, and be incubated 40 minutes, after separating with magnet, repeatedly clean through deionized water, obtain the block magnetic ferroferric oxide gel of black.The block magnetic ferroferric oxide gel of black is distributed to forms uniform n-hexane base magnetic solution in n-hexane.
Soak magnetic treatment.Active carbon is leached from dipping solution, and product n-hexane supersound washing is removed its surface and inner unsettled magnetic component, and is dried at 60 ℃ of temperature.
Sintering.With impregnation product under nitrogen protection in 200 and 450 ℃ of sintering appropriate times, obtain the magnetic active carbon product.
