Alumina Ceramic Ball and Ring for Chemical Engineering with 99% Al2O3
Inert catalyst carrier's Character:
Alpha alumina structure,High purity,low silica;
Excellent thermal and mechanical shock resistance properties;
Excellent chemical stablility with strong resisting of acid,alkaline and organic impregnant;
Inert catalyst carrier's Application:
As the covering or supporting catalyst medium of reactor column,inert catalyst carrier increase the distributing area of liquid or gas and protect well the active catalyst.It is widely used in the industry of petrol eum,chemical, fertilizer, natural gas etc.For example:the ammonia producing,methyl alcohol and hydrogen producing,abstraction of naphtha.
