In addition to the acid and alkali resistance of activated carbon, another important advantage of activated carbon as a catalyst carrier is that activated carbon-supported catalysts have higher stability and longer service life than other carrier-supported catalysts, because activated carbon supports have better resistance. Carbon formation performance.

Mo catalysts supported on activated carbon and alumina respectively are used as catalysts.coconut activated carbon Whether it is to increase the metal loading or extend the time of the catalytic reaction, the activated carbon-supported Mo catalysts have less carbon formation and longer service life. The reason is The activated carbon carrier has a weak acidity, so it prevents the catalyst from rapidly coking.

In fact, in the early studies using activated carbon as a carrier, the effect of the surface chemistry of activated carbon on the catalytic activity was not understood. carbon pellets manufacturer
By the mid-1970s, it was discovered that the properties of many activated carbon-supported catalysts could no longer be explained by the specific surface and pore structure of activated carbon alone.

It was not until the late 1980s that people began to realize the important role of activated carbon surface chemical groups on catalytic activity, and only had a more in-depth study and understanding of the importance of activated carbon surface chemical environment.
