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.

Q: No one knows the expression of the catalyst and the chemical expression of the acridine
In organic reactions, the catalyst is complex and consists of several or more. Write Chinese characters directly.
Q: Will the catalyst change the reaction rate in the chemical reaction?
Many of the catalysts are specific in varying degrees, and when added to the chemical reaction system that it can catalyze, it must change the rate of chemical reaction, and of course both positively and negatively catalyzed. Chemical reaction rate, it can not be called a catalyst.
Q: Chemical questions: "CO2 and H2 in the catalyst conditions have a reaction, the reaction of the chemical equation is"
CO2 + H2 = CO + H2O (conditions: catalyst, generally requires heating, and reversible)
Q: What is a catalyst?
In industrial production, the large amount of catalyst used frequently, the catalyst that does not change theoretically may sometimes change into another substance, which is the so-called poison of catalyst,
Q: What suitable catalysts can I use for the reaction between Hydrochloric acid and zinc metal?
catalysts are substances that alter the rate of a reaction.a suitable catalyst would be finely divided platinum.
Q: What is the catalytic efficiency of ordinary chemical catalysts?
Different reactions, with the same catalyst, the catalytic efficiency is different. The same reaction, with different catalysts, the catalytic efficiency is also different
Q: Is the chemical reaction rate constant related to the amount of catalyst used?
The catalyst has a certain amount of suitable range, the general factory production of some substances (such as ammonia), the amount of catalyst used is limited, to achieve a value after no greater role. So the reaction rate constant is independent of the amount of catalyst used
Q: Explain how catalysts help to reduce costs in industrial processes !?Thanks
they reduce the activation energy of a specific chemical reaction, which in turn reduces the temperature at which a reaction will occur at any significant rate (and therefore fuel costs) while generally making the reaction occur faster. In general, if you can catalyze a reaction, you can get away with using less robust equipment because you don't need as much energy.
Q: What is the analytical principle of chemical adsorbents? How about the number of active catalyst centers tested?
What do you mean by the chemical adsorber? BET is the use of the surface of the uneven force field, but the inert gas at low temperature in the surface adsorption. TPD, TPR is the number of active centers that can be measured by the technique of desorption and reduction between specific gases and catalysts as the temperature increases. If the active site is a reduced position, H2-TPR can be used. If the active site is acidic, NH3-TPD can be used, but also the method of alkali titration.
Q: Can you describe at least 4 ways a catalyst can lower the activation energy of a reaction?
To see how a catalyst accelerates the reaction, we need to look at the potential energy diagram shown below which compares the non-catalytic and the catalytic reaction. For the non-catalytic reaction, the figure is simply the familiar way to visualize the Arrhenius equation: the reaction proceeds when A and B collide with succificient energy to overcome the activation barrier. The change in Gibbs free energy between reactants, A + B, and the product P is delta G. The catalytic reaction starts by bonding of the reactants A and B to the catalyst, in a spontaneous reaction. Hence, the formation of this complex is exothermic and the free energy is lowered. There then follows the reaction between A and B while they are bound to the catalyst. This step is associated with an activation energy; however, it is significantly lower than that for the uncatalyzed reaction. Finally, the product P seperates from the catalyst in an endothermic step. The energy diagram illustrates 4 ways the catalyst works : The catalyst offers an alternative path for the reaction that is energetically more favorable The activation energy of the catalytic reaction is significantly smaller than that of the uncatalyzed reaction; hence the rate of the catalytic reaction is much larger The overall change in free energy for the catalytic reaction equals that of the uncatalyzed reaction. Hence, the catalyst does not affect the equilibrium constant for the overall reaction. A catalyst cannot change the thermodynamics of a reaction but it can change the kinetics. The catalyst accelerates both the forward and the reverse reaction to the same extent. In other words, if a catalyst accelerates the formation of product P from A and B, it will do the same for the decomposition of P into A and B.
