low temperature CO shift catalysts - Names and Identifiers
low temperature CO shift catalysts - Introduction
The carbon monoxide low-temperature shift catalyst is a catalyst for catalyzing the oxidation reaction of carbon monoxide. It is usually made of a stable metal oxide, such as copper oxide or iron oxide, often mixed with some promoters such as zinc, aluminum, etc.
This catalyst has the following important properties:
1. High activity: It can catalyze the oxidation of carbon monoxide at a relatively low temperature and increase the reaction rate.
2. High selectivity: It can selectively oxidize carbon monoxide without catalyzing the oxidation of other gases.
3. High temperature resistance: It has good thermal stability and can maintain activity at high temperatures.
4. Resistance to toxicity: can tolerate the presence of carbon monoxide and other toxic substances, not easy to poisoning.
The main purpose of this catalyst is to remove carbon monoxide pollutants in low-temperature combustion or oxidation reactions. It is widely used in automobile exhaust treatment, industrial waste gas treatment and indoor air purification and other fields.
The methods for preparing the carbon monoxide low-temperature shift catalyst mainly include impregnation method, co-precipitation method and vapor deposition method. One of the most commonly used is the impregnation method, that is, the metal oxide is prepared into a solution in advance, and then it is impregnated on the Catalyst Carrier, and then the preparation is completed by drying and calcination.
Regarding the safety information of the catalyst, first of all, pay attention to avoid contact and inhalation of catalyst dust, because it may cause irritation to the respiratory tract and skin. It is necessary to pay attention to the stability and thermal stability of the catalyst during use, and avoid use in high temperature and high pressure environments. In addition, the by-products produced during the use of the Catalyst also need to be treated to avoid pollution and harm to the environment and the human body. It is best to follow the relevant safe operation guidelines and specifications.
