Activated carbon mercury catalyst is widely used in thesynthesis of PVC raw material. Without the application of activated carbonmercury catalyst, the cost of PVC raw materials will be greatly increased,which will directly cause the higher price of PVC, and directly affect thescope of PVC usage.
What is PVC?
PVC is one of the five general-purpose plastics, and its products are widely used in soft products such as packaging plastics, artificial leather, plastic products, and hard products such as pipes and plates.
In modern chemical production, more than 90% of the reaction processes require the participation of catalysts (commonly known as catalysts).
What is the catalyst?
The catalyst is a substance that can change the chemical reaction rate ( increase or decrease) of the reactants in a chemical reaction without changing the chemical balance, and its quality and chemical properties have not changed before and after the chemical reaction.
What is the catalyst for the synthesis of vinyl chloride?
The mercuric chloride catalyst was prepared by using the selected imported coconut shell activated carbon as the carrier and mercuric chloride as the main active component. The mercuric chloride catalyst supported by the activated carbon and the single metal mercury as the carrier was prepared by the special impregnation method.
The catalyst for the synthesis of vinyl chloride features
- Large active specific surface area
- High conversion rate of vinyl chloride
- The temperature of the reaction bed is uniform and stable
- Strong anti-toxic ability, small loss of mercury chloride,low consumption
- Low packing density
Application of mercury catalyst
For PVC production, there are two main methods, that is, the ethylene method and the calcium carbide method. my country mainly adopts the calcium carbide method PVC.
In the production of polyvinyl chloride (PVC) by the calcium carbide method, activated carbon is used as a carrier to obtain mercury chloride contacting coal. Mercury chloride catalysts are used in organic synthesis reactions as catalysts in the process of synthesizing vinyl chloride(VCM) from acetylene and hydrogen chloride.
Under the synthesis reaction conditions, the sublimation of mercury chloride is carried out of the synthesis reactor by VCM, and enters the subsequent purification system; it passes through the activated carbon mercury removed, acid washing tower, water washing tower, and alkali washing tower, and then enters the VCM distillation and polymerization device after drying.
