Patent number: 4179411Abstract: A method for preparing an alumina having controlled pore volume distribution is disclosed. The method requires the presence of 0.1-15% by weight of a water soluble aliphatic polycarboxylic acid having from 2-12 carbon atoms based on the dry weight of Al.sub.2 O.sub.3, during alumina precipitation. The resultant calcined alumina has a pore volume distribution such that:A. Nitrogen desorption measurements indicate that less than 10% of the total pores as determined by said method fall between 100-1200A in diameter;B. Nitrogen adsorption measurements indicate that between 10-50% of the total pore volume as determined fall between 100-1200A in diameter; andC. Mercury penetration porisimetry indicates that less than 10% of the total pores as determined by both nitrogen desorption and mercury methods fall between 100-50,000A in diameter.Type: GrantFiled: November 10, 1977Date of Patent: December 18, 1979Assignee: Nalco Chemical CompanyInventors: Frank R.
