[Uses]
There is an appropriate oxidation reaction rate. Non-toxic, odorless, safe, reliable performance, and in line with food hygiene requirements. The effect is stable, with an average of 104 ml of oxygen per gram of sample. It is used for oxygen insulation protection of various bagged foods, traditional Chinese medicine, furs, artworks, cultural relics, metal products, etc., and can prevent mold, insects, rust, fading and oxidation. There are many types of oxygen that isolate some things that are easily damaged in oxygen.
(2) What is a catalyst?
Definition: According to the definition proposed by IUPAC in 1981, a catalyst is a substance capable of accelerating the rate of a reaction without changing the standard Gibbs free enthalpy change of that reaction. This action is called catalysis. The screening involving catalysts is a catalytic reaction.
(3) What is catalytic activity?
catalytic activity
It refers to the ability of substances to catalyze, which is one of the important qualities of catalysts. The catalytic activity of a substance is for a given chemical reaction. In industrial production, it is often expressed as the number of raw material reactants converted per unit volume (or mass) catalyst per unit of time in a unit of time, such as the number of kilograms that each cubic meter catalyst can convert into raw materials per hour. Since solid catalyst action is a surface phenomenon, catalytic activity is related to the size of the specific surface area of the solid, the properties of the active centers on the surface, and the number of active centers per unit surface area. In order to describe the difference in catalytic activity of different substances, the number of catalysts that can convert raw materials per unit unit surface area in a unit time is often referred to as the specific activity. The number of molecules transformed by each active center in 1 second is called the number of turnovers or conversions. The catalytic activity of a substance to a specific reaction is related to the reaction conditions, such as the concentration of reactants, the reaction temperature, etc., so the reaction rate constant and activation energy in the reaction rate equation are also commonly used to characterize the activity of the catalyst. Typically, highly active catalysts exhibit catalytic activity at lower temperatures. Some substances can exhibit catalytic activity at very low concentrations or small specific surface area, such as the walls of some metal containers. However, most of the commonly used industrial catalysts are materials with large specific surface area, for example, nickel blocks do not show obvious catalytic activity for hydrogenation of oils and oils to hardened oils, while nickel with high dispersion is a good catalyst. The activity of catalysts is not static, and due to catalyst poisoning, sintering and other reasons, the catalyst will gradually decline during use and eventually lose its activity. If the same catalyst can catalyze more than two reactions in a reaction system, the ratio of the catalytic activity of the catalyst to different reactions determines its catalytic selectivity for a particular reaction (see Catalyst Selectivity). Catalytic activity can be measured in the laboratory with a special device, that is, feedstock is injected into a reactor containing a catalyst, and the reaction is carried out under specified reaction conditions, and the amount of raw material consumption and the number of products produced before and after the catalytic reaction are measured. However, the catalytic activity exhibited when used in industrial installations is not necessarily the same as laboratory results, as it is also related to the design of the reactor, operating conditions, purity of the reactants, and the tooth of the catalyst used (indicating how long the catalyst has been used).
