I. Application
a-Al2O3 carrier is Al2O3 as the main component, and add the appropriate alkaline additives, after 1400 ºC and above the high temperature calcination and become; widely used in petroleum, chemical, fertiliser, natural gas and environmental protection and other industries, mainly as a light hydrocarbon steam reforming catalyst carrier, hydrogenation catalyst with protective agent. It has the characteristics of high temperature and high pressure resistance, stable chemical performance; it can withstand the corrosion of acid, alkali and other organic solvents, and can withstand the temperature changes in the production process.
γ-Al2O3 carrier is made of activated alumina as the main material, and appropriate additives (e.g. Ti, Mg, etc.) can be added according to the use of catalyst, the catalyst prepared with this carrier has higher activity and activity stability compared with similar products, and it is more suitable for the use in the harsh conditions of high temperature, high pressure, high airspeed, and high water/gas ratio. This kind of carrier is made by special process, so it has unique skeleton structure, so it has strong affinity with active components, uniform distribution of micropores, suitable pore size, large pore capacity, high water absorption, low bulk density, good mechanical properties, and good stability. Mainly used in chemical fertiliser, oil refining, gas purification and other chemical related industries.

III. Performance Characteristics
Adding special additives, the acidity and alkalinity are more reasonable.
Adopting special processing technology, the density of the carrier is lighter and the strength is higher.
Calcined at a high temperature above 1400ºC, good thermal stability.
IV. Application Fields
Petroleum, chemical, fertiliser, natural gas and environmental protection industries.
V. Packaging, storage and transport
Finished products are packed in plastic drums or iron drums lined with plastic bags, in the process of transport, storage must be moisture-proof, fire-proof, anti-inversion and prohibited chemical contamination, handling is strictly prohibited rolling or impact; open storage, the bottom of the cushion sleeper, the top of the canvas to prevent rain; also according to the user's needs to be packed in tonnes of bags.
