α-Al2O3 Type Carrier with High Strength
I. Applications
α-Al2O3 type carrier is mainly composed of α-Al2O3, with appropriate alkaline additives added, and calcined at a high temperature of 1400°C and above; widely used in petroleum, chemical, fertilizer, natural gas and environmental protection industries, mainly as a carrier for light hydrocarbon steam reforming catalysts and a protective agent for hydrogenation catalysts. It has the characteristics of high temperature and high pressure resistance and stable chemical properties; it can withstand corrosion from acids, alkalis and other organic solvents, and can withstand temperature changes occurring in the production process.

III. Performance Characteristics
Special additives are added to make the acid-base properties more reasonable;
Special processing technology is adopted, the finished carrier has lighter bulk density and higher strength;
Calcined at high temperature above 1400°C, good thermal stability.
IV. Application Fields
Petroleum, chemical, fertilizer, natural gas and environmental protection industries.
V. Packaging, Storage and Transportation
The finished product is packaged in plastic drums or iron drums lined with plastic bags. During transportation and storage, it must be protected from moisture, fire, inversion and strictly prohibited from chemical contamination. Rolling or impact is strictly prohibited during handling; when stored outdoors, the bottom should be padded with sleepers and covered with canvas for rain protection; it can also be packaged in ton bags according to user needs.
