HTS-3 series of hydrogenation arsenic protection agent

Release time:2017-04-10 17:40:39    source:

Trace arsenic can make the catalyst poisoning, reduce or even lose its activity. Often the hydrogen content of the hydrotreating unit is less than 200 ppb and the arsenic content of the reformer is less than 1 ppb. HTS-3 series of hydrogenation arsenic, is my company provides a good dispersion of the active ingredient, the same amount of high activity of high temperature arsenic removal agent. The agent has the advantages of high arsenic content, high arsenic removal rate, good stability and high strength, and also has good accretion function, which can be used as supporting protective agent and various hydrogenation catalyst. The agent can be used in both vulcanized and non-vulcanized vulcanized conditions. This method has been used continuously for more than three years, and the arsenic content in the raw material can be reduced from 313ppb to below 1ppb, which shows good arsenic protection.
The main properties of the HTS-3 series of hydrogenation arsenic are shown in the following table
