Aluminum Sulfate No Fe Qualifed Grade in China

3.Applications:

Water effluent treatment system
It's used for purification of drinking water and wastewater treatment by settling of impurities by

means of precipitation and flocculation.

Paper Industry
It helps in sizing of paper at neutral and alkaline pH, thus improving paper quality (reducing spots

and holes and improving sheet formation and strength) and sizing efficiency.

Textile Industry
It is used for color fixing in Naphthol based dyes for cotton fabric.

Other Uses
Leather tanning, lubricating compositions, fire retardants; decolorizing agent in petroleum, deodorizer; food additive; firming agent; dyeing mordant; foaming agent in firefighting foams; fireproofing cloth; catalyst; pH control; waterproofing concrete; aluminum compounds, zeolites etc.

4. Package:

Packaging Detail: PP/PE 50kg/bag;25kg/bag;Jumbo bag or according to customers' requirements.

20-25MT will be loaded in per 20'FCL container.

5. Attention and Storage:

The product is liable to absorb moisture and clot due to long-term exposure, so shady, cool and ventilated environment is needed.

Q:About the catalyst?
Catalysts are not used/destroyed in any reactions, it merely speeds up the process by lowering the reaction activation energy. It functions by being able to weaken or break the required bonds necessary in the chemical reaction (thus lowering activation energy) through temporary and weak bonding to form a complex. In this case the H2O2 molecule will bind with the MnO2 molecule due to the complimentary sites (thus forming a complex) to weaken the bonds for decomposition, but after decomposition the products (oxygen and water molecules) break off from the catalyst (as there are no more complementary sites with them) thus the catalyst will not be destroyed.
Q:TEN POINTS!! How is the catalyst affected by vinegar?
The catalyst is affected by vinegar because vinegar is acidic meaning there are more H+ ions. This alters the charges on the R groups of the amino acid residues of the enzyme molecule. The bonds that help maintain the conformation of the enzyme molecule which is ionic will therefore, be disrupted and the binding of substrate will be affected. However, if pH is restored to optimum pH, the maximum activity of the enzyme will be restored but this is only if the pH was only altered by a small extent. If pH is altered by a large extent, the conformation of the enzyme molecule will be severely affected causing it to denature. The catalyst is affected by heat because excessive heat disrupts the intermolecular bonds which stabilise the secondary and tertiary structure of an enzyme molecule(the enzyme molecule has a tertiary structure). The enzyme molecule unfolds and the precise shape of the active site is lost. This loss of structure and function is irreversible.
Q:why is palladium/platinum a good catalyst?
Palladium and platinum are good catalysts because they _adsorb_ certain molecules, especially gases. Adsorption is NOT the same as _absorption_. Adsorption is a process by which a chemical (gases or liquid) physically becomes attached to the _surface_ of an adsorbate (a solid). Once gas molecules are adsorbed on the surface of a catalyst, they are much nearer each other and more likely to react. Absorption is a process by which a gas or liquid is incorporated throughout the volume of an absorbate (a solid), rather than just on the surface. The fact the palladium happens to _absorb_ hydrogen molecules well probably has little to do with its function as a catalyst and is probably just a coincidence. In fact, two of the main reactions in a catalytic converter don't involve molecules with hydrogen atoms at all. On the other hand, WHY platinum and palladium are good catalysts are a mystery. Presumably, they are good at enhancing the Van der Waals forces that cause adsorption with other molecules, but WHY the platinum family of metals do this better than other metals is not fully understood (I don't think).
Q:Manganese dioxide can be used as a catalyst for various chemical reactions
The reactor may be a reactant,
Q:Biological enzymes and chemical catalysts of the differences in the source
Catalyst catalytic reaction relative conditions higher, selectivity than biological enzymes
Q:How do enzymes / catalysts in biology and chemistry in high school stage give different feelings?
I do not know the main high school teachers have done with fresh chicken liver grinding solution and ferric chloride solution compared to the decomposition of H2O2 catalytic efficiency of the experiment, the result is ferric chloride plus H2O2 slowly take the bubble, add fresh chicken cups Quickly take bubbles and liquid spill. Indicating that the enzyme is a catalyst, and the catalytic efficiency is far higher than the inorganic catalyst.
Q:Will the chemical catalyst not reduce that?
Why is it done? Although the catalyst does not react chemically, the catalyst itself is deteriorated and is not always used
Q:Is the catalyst considered a chemical reaction?
The catalyst is involved in the reaction, but in the reaction process is a step in the effect of its shape has not changed, so that did not participate in the reaction.The role of the catalyst is to reduce the activation energy of the reaction, the original one reaction into two or Multiple reactions, each sub-reaction of the activation energy is very low, the reaction is very good, the effect is the total reaction faster. Hope to adopt
Q:What are the methods of catalyst characterization?
Catalyst characterization is through the physical or chemical detection test means, the structure and nature of the catalyst to give a state description, to help explain the characteristics and characteristics of the catalyst,
Q:what is a fuel catalyst?
