Summary: | The present invention is directed to a high surface area, high pore volume porous alumina, comprising: aluminum oxide, optionally, silicon oxide and aluminosilicates, and optionally one or more dopants, said alumina having a specific surface area of from about 100 to about 500 square meters per gram and a total pore volume after calcination at 900°C for 2 hours of greater than or equal to 1.2 cubic centimeters per gram, wherein less than or equal to 15% of the total pore volume is contributed by pores having a diameter of less than 10 nm.
La présente invention concerne de l'alumine poreuse à surface active et volume des pores élevés, qui comprend: de l'oxyde d'aluminium, éventuellement de l'oxyde de silicium et des aluminosilicates, et éventuellement un ou plusieurs dopants. Cette alumine présente une surface active spécifique d'environ 100 à 500 mètres carrés par gramme et un volume total des pores supérieur ou égal à 1,2 centimètres cubes par gramme après 2 heures de calcination à 900°C, 15% au plus du volume total des pores étant constitués de pores dont le diamètre est inférieur à 10 nm. |
