The present invention relates to a porous alumina having a high surface area and a high pore volume comprising aluminum oxide, optionally silicon oxide and aluminosilicate, and optionally one or more dopants, wherein the alumina is at 900 ° C. for 2 hours. After calcination, the specific surface area of about 100 m 2 / g to about 500 m 2 / g and the total pore volume of 1.2 cm 3 / g or more, and pores less than 10 nm in diameter occupy less than 15% of the total pore volume. |
