OXYGEN CARRIER PARTICLES AND METHOD FOR MANUFACTURING SAME

摘要

The present invention relates to oxygen carrier particles, the material composition of which includes: an active material containing a metal oxide; and a support material which contains hydrotalcite or a mixture of hydrotalcite and gamma-alumina. The use of the support material of the present invention enables the manufacture of oxygen carrier particles having high reactivity and physical characteristics, such as high strength, even at a low firing temperature so as to be suitable for use in a liquid layer process.
