How to choose the right chemical catalyst-stability

There are many kinds of chemical catalysts and their applications are extremely wide. The performance of different catalysts in the same reaction and even in the same device is also very different. So what kind of catalyst is a good chemical catalyst and how should it be evaluated? What indicators should be paid attention to when choosing a chemical catalyst? Generally speaking, the three comprehensive indicators of activity, selectivity and stability are mainly used to measure the quality and efficiency of a chemical catalyst. Also related to these three items are the mechanical strength, toxicity resistance, geometric physical properties, macroscopic and microscopic physical structures, and economic performance of the catalyst. A more comprehensive performance overview is shown in the table below.

What are the selection criteria for nickel catalysts

At present, there are many nickel catalyst manufacturers in China, most of the small factories have weak technical strength and backward production process, and the quality of nickel catalyst products is greatly affected by human factors. Next, we will tell you the selection criteria for nickel-based catalysts. The quality control method of nickel-based catalyst is the activity test of the product, and there is still a lack of quality control of semi-finished products in the production process. Therefore, nickel catalyst users should choose those production process and equipment to win, product quality is stable, but also have the use of service conditions of the unit production of the best high-efficiency nickel catalyst. Generally, nickel catalysts with high activity, high load bearing, good strength, selectivity and good toxicity resistance should be selected.

What are the uses of Raney nickel catalysts

Raney nickel catalyst as a spark, has been used in various industries, and has been well received by users. So what are the uses of Raney nickel catalysts? Let's tell you! This Raney nickel catalyst is mainly used in the catalytic hydrogenation reaction of basic organic chemical industry. Can be used for hydrogenation of organic carbon-hydrogen bonds, hydrogenation of carbon-nitrogen bonds, hydrogenation of nitroso compounds and nitro compounds

How to use nickel catalyst reasonably

The deactivation of the nickel-based catalyst is greatly related to the conditions of its use. Excellent catalytic performance is the basis for the use of nickel-based catalysts, and good conditions of use are the guarantee of the quality of nickel-based catalysts. Today we will share with you how to use nickel catalysts reasonably.

Problems needing attention in the selection of copper-based catalyst regeneration

Copper catalyst is also called coal, is a kind of only change the speed of the chemical reaction without changing the essence of the reaction, plays a very obvious acceleration. Next, we will introduce the problems that need to be paid attention to in the selection of copper catalyst regeneration. It is 1. to pay attention to whether the product performance after regeneration is stable or not. Due to the influence of various factors such as humidity and temperature in the air, the activity of the copper catalyst is lost and cannot continue to exert its effectiveness. The copper-based catalyst regeneration plant will temporarily lose the activity of the catalyst or collect some of the substances for recycling, although the possible regeneration of the catalyst in the service life can not reach the original level, but the performance still has good stability.

What are the causes of catalyst deactivation and what should be paid attention to in industrial use

The chemical composition of the catalyst does not change before and after the chemical reaction, and the life of the catalyst is theoretically infinite. But in actual use, the catalyst has a certain life, and sometimes, the life is far shorter than imagined. Next, we will tell you the reasons for the deactivation of the catalyst and the matters needing attention during use.

Several Causes of Deactivation of Hydrogenation Catalyst

Hydrogenation catalysts are affected by various factors during use, and will lose their activity sharply or slowly. Today, Xunkai Catalysis briefly introduces several reasons for the deactivation of hydrogenation catalysts. 1, permanent deactivation, hydrogenation catalyst active components by the role of some foreign components (poisoning) and lose activity, often permanent deactivation. Most of these foreign components are chemically reacted with the active components of the catalyst or ion exchange, resulting in changes in the active components. Deactivation of catalyst poisoning often manifests itself as a rapid decline in activity. Loss of active components due to wear or sublimation during use also leads to permanent deactivation, which is often difficult to recover simply.
