Applocation:

  1.     Battery Dedicated CMC has good hydrophilicity and good compatibility ,and it is mixed well with various metal powders

  2.     The metal ions the produce is extreme tiny,replacing unfiomly,stable viscosity,strong adhesion force,water solution with high transparency ,and good flow performance


  3.   It can increase the coltage platform of the battery,reduce the internal resistance of the battery,reduce the internal pressure if the battery,improve the high-current performance of the battery.




Package and Storage:

1. The solid product can be packed in inner plastic bags, and further in polypropylene woven bags with each bag containing 25Kg.

2. The solid product should be prevented from scattering on the ground because the hygroscopic powder can cause slipperiness.

Q:What happens to the rate of a reaction when the concentration of a catalyst is doubled?
A catalyst speeds up a chemical reaction by providing an alternate reaction pathway with a lower activation energy, thus increasing the number of collisions that can result in the formation of product. When the catalyst is a reactant in the rate determining step, and the reaction is first order in the catalyst, then a doubling of the concentration will double the rate. But if the rate determining step which includes the catalyst is not first order, then doubling the concentration won't double the rate. Then there is the case of a heterogeneous catalyst in which the reaction is essentially zero order in the catalyst. The amount of catalyst won't affect the speed of the reaction beyond the initial increase. The mere fact that the catalyst is present speeds up the reaction.
Q:PT / AL_203 catalyst and the main chemical use
Yueyang Eagle Hill Petrochemical Plant
Q:what is a catalyst ?
OK- First about what a catalyst does. All reactions require some amount of energy to proceed. For most of of these it is not much and it comes from the reactions immediate environment and we don't notice it. This energy needed is called an energy threshold. Many, if not all, reactions can have their thresholds lowered by something else-platinum-nickle in the cars catalytic converter does this. Catalysts are not used in the reaction so the catalyst, once added, stays there and continues working. By the way, in biology we have organic catalysts (the enzymes).
Q:What is positive and negative catalyst in chemistry?
Positive catalyst can speed up the reaction rate, negative catalyst can slow down the reaction rate
Q:describe a biological catalyst?
Biological catalysts work in similar fashion to inorganic catalysts. The lower the activation energy (Delt. G) of the rate limiting step in an SN1 or SN2 reaction. However, they are comprised of biomolecules susceptible to degradation and are quite sensitive to temperature change.
Q:What is catalyst in Science?
not all catalyst are enzymes. There are biological catalysts as well as non biological ones catalysts are something that speeds up the rate of a chemical reaction without itself getting altered after it. for example an enzyme is a catalyst because it speed up the rate of food digestion (by breaking down food molecules) and doesn't get altered after the reaction.
Q:Several experiments were carried out using catalysts
Hydrogen peroxide in the manganese dioxide as a catalyst for decomposition reaction: 2H2O2 == MnO2 == 2H2O + O2 ↑ (laboratory oxygen principle)
Q:Exemplify the use of green catalysts in green chemistry
How can a green catalyst, they do not react
Q:Biology Question - Catalysts?
Organic or Inorganic - the catalyst (enzyme) must be organic to be found in the cell. Catalysts speed up chemical reactions inside a cell and must therefore be organic to be a functioning part of the cell. Reusable - There are so many reactions that catalysts are involved in that it would be a waste for the cell if a catalyst could only last one reaction, especially if there are inhibitors and competition for the active site. Catalysts must be reusable in order to keep the cell functioning. Catalysts always remain unchanged after a reaction. HIihly Specific - Catalysts are only made to catalyze one specific chemical reaction. Their active site has proteins bonded in such a way that only certain elements can enter the active site and H bond with those proteins. The fact that they are highly specific maximizes the productiveness of the cell. And it ensures that the cell only has catalysts to reactions that it needs to be completed. It also ensures that the elements are correctly bonded with eachother. If any two elements could enter the active site, there is no guarantee that the correct product will be produced. Catalysts and Enzymes must be super highly specific in order to properly function. Lowers Activation Energy - The more energy a cell has to spend to catalye a reaction, the worse it is for the cell and the less ATP is has for other reactions. Catalyts hold the substrates together so there is less energy that is needed to have the two substrates react with eachother. Activation Energy is the energy that is needed to start a reaction. So the less energy used by the cell for reactions, the better for the cell. Hope this helps
Q:A catalyst elevates the rate of a reaction by?
lowering the activation energy needed for the reaction to occur.
