Abstract
This paper serves as an introduction to the technology of alumina catalyst supports and relates physical and chemical properties of aluminas to the critical properties of finished catalysts. Although the emphasis here is upon the design of particulate catalyst supports, the treatment is sufficiently broad to be applicable in part to the use of aluminas in other ways, such as for coatings on other substrates.
The information presented will be of greatest interest to those directly involved in catalyst development and manufacture, representing the viewpoint of a supplier of raw materials and formed alumina substrates to the catalyst industry. However, it may also appeal to those wishing to develop a further background on catalyst properties and gain some understanding of the limitations of feasible design of catalysts, which, in turn, often depends upon the flexibility and limitations of the catalyst support employed.
A number of physical property measurements important to overall converter operation, and thus technical considerations of importance to the catalyst support material alone are briefly described.
