Abstract
Mesoporous, alumina compositions having an average pore diameter substantially ranging from about 15 .ANG. to about 40 .ANG. and an average surface area of no less than about 500 meter square/gram are disclosed. These materials can be formed by treating an aluminum source that is derived from an aluminum alkoxide in an organic-aqueous solution with an organic structured directing agent to form meso-sized micelles followed by calcination of the resulting composition. Appropriate organic structural directing agents are alkyl carboxylic acids.
