Characteristics
Application and operating conditions
Inert alumina ceramic balls are widely used in refining, petrochemical, coal chemical, chemical fertilizer, natural gas chemical and environment protection industries, etc. As the catalyst supporting and covering material inside the reactor, it can buffer the impact of incoming process media on the catalyst, playing a role of protecting the catalyst and improving the distribution of process media.
