Zinc Acetate Catalytic Activated Carbon – Heycarbons Manufacturer From China

What is Zinc Acetate Catalytic Activated Carbon?

Zinc acetate catalytic carbon refers to a catalytic material in which zinc acetate (Zn(CH3COO)2) is supported on activated carbon. It is a typical metal salt supported activated carbon catalyst.

This material is widely used in petrochemicals, acetylene chemicals, fine chemicals, and some plastic monomer synthesis fields. Among them, the most typical and industrialized application is as a catalyst for the synthesis of vinyl chloride (VCM) in the PVC (polyvinyl chloride) production process.

Zinc Acetate Catalytic Carbon Mechanism

In petrochemical and acetylene chemical processes, zinc acetate catalytic carbon is mainly used as a catalyst for the hydrochlorination of acetylene. It can activate HCl and acetylene and promote the chlorination addition reaction on the surface of activated carbon, thereby achieving efficient synthesis of VCM. The chemical reaction formula is:

C2H2+HCl → CH2=CHCl

The resulting vinyl chloride (VCM) can be further polymerized to produce polyvinyl chloride (PVC) plastic.

Why Activated Carbon Is Used as a Catalyst Support?

Activated carbon has a well-developed pore structure and a large specific surface area, which can uniformly disperse the Zn²⁺ active component on the support surface, thus providing more catalytic active sites.

At the same time, the pore structure of activated carbon facilitates the adsorption, mass transfer, and diffusion of HCl and acetylene molecules, making it easier for reactants to contact and react within the pores, thereby improving catalytic efficiency and reaction rate.

Heycarbons Zinc Acetate Catalytic Carbon Product

Heycarbons zinc acetate catalytic activated carbon product, this material uses high specific surface area activated carbon as a carrier and zinc acetate as the active component. It has a well-developed pore structure, good dispersion of the active component, and stable catalytic performance, and can be widely used in chemical catalytic systems such as acetylene hydrochlorination and VCM synthesis.

Coconut Shell Zinc Acetate Catalytic Activated Carbon Specification

Coconut shell activated carbon typically has a well-developed micropore structure and a high specific surface area, providing numerous sites for Zn2+ to adhere. Low ash content facilitates the uniform dispersion of Zn2+. High mechanical strength prevents the pore structure from collapsing or pulverizing during impregnation and drying. Therefore, coconut shell activated carbon more readily forms a stable, uniform, and highly dispersed catalytic layer.

The specifications of Heycarbons zinc acetate catalytic carbon from coconut shell are shown in the table below:

Heycarbons Zinc Acetate Catalytic Carbon	Specification
Material	Coconut shell
Size	Pellet 4mm; Granule 20-40 mesh
Iodine value	1000-1500 mg/g
Ash	3% (1-2% after acid washing)
Stregth	95-99.8%
Load capacity	35%

Heycarbons’ zinc acetate catalyst has a loading of approximately 35%, resulting in relatively dispersed Zn, high active site density, and minimal micropore blockage. A 35% loading often represents a balance between performance and stability. This is a crucial indicator for high-performance VCM catalysts.

Zinc Acetate Catalytic Activated Carbon Features

Advantages of Zinc Acetate Catalytic Activated Carbon for VCM Production

Compared to traditional mercuric chloride (HgCl₂) catalysts, zinc acetate catalytic carbon does not contain highly toxic heavy metals such as mercury, effectively avoiding mercury pollution and exhibiting better environmental performance.

Raw materials are widely available, resulting in relatively low production costs.

The process technology is relatively mature; among existing mercury-free catalytic systems, zinc-based catalysts are considered one of the routes closest to industrial application.

Disadvantages of Zinc Acetate Catalytic Activated Carbon for VCM Production

Despite its superior environmental performance, its overall catalytic performance is still lower than that of traditional mercury-based catalysts.

The relatively low catalytic activity of zinc acetate catalytic carbon leads to lower conversion and yield of vinyl chloride (VCM) compared to HgCl₂ catalytic systems.

During long-term operation, it may also experience rapid activity decay and insufficient stability.

Heycarbons Zinc Acetate Catalytic Carbon Other Applications

Besides the acetylene hydrochlorination reaction, the zinc acetate catalytic carbon system can also be applied to:

Vinyl acetate synthesis
Esterification reaction
Hydrodesulfurization auxiliary catalysis
VOC catalytic oxidation
Some olefin conversion, etc.

Among these, the most mature and representative industrial application remains the acetylene-based PVC production.
