Activated alumina is white spherical porous granules, smooth
surface, uniform particle size, non-toxic, odorless, tasteless,
insoluble in water, alcohol and organic solvents, but insoluble in
acids and alkalis.Â
Yuanying activated alumina has strong moisture adsorption, high
mechanical strength, big specific surface area, large pore volume,
high pressure-resistant, high wear-resistant, stable chemical
properties, not burst after absorbing water
There are the following types of products: activated alumina
desiccant, defluorination agent, activated alumina catalyst
carrier, activated alumina for hydrogen peroxide, sulfur recovery
catalyst, potassium permanganate ball, dechlorination agent.
Activated Alumina Defluorinating Agent
Yuanying activated alumina defluorinating agent has high
defluorination capacity, and it is non-toxic, tasteless, odorless,
insoluble in water and organic solvents.
Widely used for fluoride removal in high fluoride area, cyclic
alkanes defluorinating agent among alkylbenzene production. This
product can also be used for dearsenification, wastewater
decolorizing, deodorizing, etc.
Activated alumina defluorinating agent is white spherical porous
particles, uniform particle size, smooth surface, high mechanical
strength, hygroscopicity strong, does not crack and inflate after
absorbing water.
Fluorine is one of the trace element necessary for animal and
human. Adult normal daily intake should be 2~3 mg, too much or too
little can lead to disease, so defluorination is important in
drinking water. Activated alumina has good strength, good abrasion
resistance, long service life, stable performance, high
defluorination capacity, after defluorination the water quality
accords with national health standards, so activated alumina is one
of the indispensable material in water treatment.
Activated alumina defluorinating agent has amphoteric adsorption
properties, by regulating the PH value of aqueous solution, anions
in aqueous solution can be detached. Defluorinating equipment is
similar to ion exchanger, in order to obtain high defluorination
capacity, need to lower PH value, while the PH value is 5.5,
activated alumina adsorption rate of fluorine is the largest. In
order to meet the quality requirement and control corrosion, PH
values should be slightly acidic. Activated alumina defluorination
is similar to the anion exchange resin, but the selectivity for
fluoride ion is larger than the anion resin.
Smaller particle size can increase specific surface area, make a
fully contact between activated alumina and water. For example,
commonly used **3 mm, 0.**1.2 mm, their specific surface area are
generally more than **0 m2/g. High specific surface area means huge
number of micropore, it can ensure a strong adsorption of fluoride
ion in water. When raw water PH value and alkalinity is lower,
defluorination capacity of activated alumina is higher, fluoride
absorption of per cubic meter activated alumina is ***0 grams,
fluoride absorption capacity is greater than 4.0mg/g, and the price
is lower than synthetic resin.
Activated Alumina for Hydrogen Peroxide
Activated Alumina for hydrogen peroxide is white, spherical porous
material and is non-toxic, odorless, tasteless. It is insoluble in
water, esters, hydrocarbons, alcohols and other organic solvents.
It has long life, not powdering and softening in water and alkali,
is a special adsorbent for anthraquinone production of hydrogen
peroxide.
Besides adsorbing alkali in the working fluid, it also has strong
reproductive property to the hydrogenation breakdown products, and
the increase of degradation products in the hydrogenation reaction
can be converted into the active anthraquinone, which can ensure
the stability of the total effective amount of anthraquinone, and
is conducive to the oxidation reaction, so it can reduce the amount
of anthraquinone added, saving the running cost.
Considered the regeneration, this product guarantees the good
machine capability, and the active changes small after
regeneration.
Activated Alumina Catalyst Carrier
Yuanying activated alumina catalyst carrier is a white, spherical
porous material, non-toxic, odorless, not powdering, insoluble in
water and alcohol. It has even micro-holes, appropriate aperture
size, big pore volume, high water absorption, small bulk density,
good mechanical properties, good stability, suitable for catalyst
Carrier.
Application
(1) The Co-Mo sulfur-resistant shift catalysts produced by
Activated alumina catalyst carrier has good low-temperature
activity, width working temperature, short vulcanization time and
other merits, it is applicable to small and medium sized ammonia
factory.
(2) In the natural gas and petrochemical refining industrial
process, to the hydrogen sulfide, can use activated alumina as
catalyst for sulfur recovery.
(3) The most widely application for activated alumina catalyst
carrier is hydrotreating, it can raise H/C ratio and get rid of O,
S, N, finally can remove V, Ni and other contaminants.
(4) Another application for the activated alumina catalyst carrier
is automobile exhaust catalyst, it can promote the oxidation of
hydrocarbons, carbon monoxide and nitric oxide in exhaust gas,
reduce air pollution.
(5) In the petroleum hydrocracking, hydrogenation refining,
hydrogenation reforming, drogenation reaction and automobile
exhaust purification process, activated alumina catalyst carrier
plays an important role.
(6) Used for Alcohol dehydration, olefin isomerization,
hydrogenation, oxidation and polymerization.
γ-Al2O3, was called activated alumina, is a kind of porous high
dispersion solid materials, because of its adjustable pore
structure, large specific surface area, good adsorption
performance, surface with the advantages of acidity and good
thermal stability, microporous surface with requisite properties of
catalytic action, therefore become the most widely used catalyst,
catalyst carrier and chromatography carrier in the chemical and oil
industry, and plays an important role in the oil hydrocracking,
hydrogenation refining, hydrogenation reforming, dehydrogenation
reaction and automobile exhaust purification process.
γ-Al2O3 is widely used as catalyst carrier because of the
adjustability of its pore structure and surface acidity. When γ-
Al2O3 is used as a carrier, besides can have the effects to
disperse and stabilize active components, also can provide acid
alkali active center, synergistic reaction with the catalytic
active components. The pore structure and surface properties of
catalyst depend on γ-Al2O3 carrier, so high performance carrier
would be found for specific catalytic reaction by controlling the
properties of γ-Al2O3 carrier.
