The dechlorinating agent can be used for fine dechlorination in the production processes of synthetic ammonia, methanol, methanol, methanation, etc., as well as in the fine dechlorination of gaseous hydrocarbons, hydrogen, hydrogen nitrogen, semi water gas, coke oven gas, decarbonization gas and other gases, with a wide range of applications.
Chinese name
Dechlorination agent
Features
High dechlorination precision, fast reaction speed, etc
Activated aluminaThe dechlorinating agent is mainly used to remove impurities such as hydrogen chloride in petroleum and petrochemical industries, and can also remove hydrogen chloride from chlorinated alkanes to generate olefins.The dechlorination agent has excellent performancemetallic oxideIt is an active component and is prepared by special process.The dechlorination agent is suitable for fine dechlorination of various chemical feed gases and liquid hydrocarbons under normal and low temperature conditions.At low temperature (- 4~100 ℃), it has high chlorine capacity and removal accuracy.Even if the chlorine content in the raw material is up to 200ppm, the chlorine content after treatment is still less than 0.1ppm.

Precautions for filling of dechlorination agent
The filling of dechlorinating agent directly affects the use effect, which must be paid great attention to
1. The filling of dechlorinating agent shall not be carried out in rainy days, so as not to affect the use effect of dechlorinating agent.
2. Before filling, check whether there is obvious powder layer during transportation and loading. If there is, filter the dechlorination agent.
3. The filling volume shall be calculated and the height diameter ratio shall be greater than 3.0.
4. Lay 8-10 mesh stainless steel wire mesh on the plate of reactor, and then fill with dechlorination agent.If the gas is from the bottom to the top, a layer of 8-10 mesh stainless steel wire mesh must be laid on the dechlorination agent and fixed.
5. Special filling tools shall be used, and the discharge pipe shall be able to rotate freely, so that the materials can be filled evenly in the reactor. It is forbidden to pour the dechlorination agent from the middle or fixed parts.
6. It is forbidden to step on the dechlorination agent during filling.[1]
