| abstract |
An alumina support composition comprising at least 0.1% by weight of silica is disclosed. Wherein the alumina support has a pore volume greater than 0.60 cc / g, a median pore size in the range of from about 70 A to about 120 A, a pore size distribution such that 90% or more of the total pore volume lies in the range of about 20 A to about 250 A, Or more pore size distribution width. The alumina composition of the present composition exhibits a first peak mode at a pore diameter less than the median pore diameter. Also provided are catalysts made from the alumina support and methods of making and using the supports and catalysts. |
