| abstract |
Alumina support compositions comprising at least 0.1 wt.% Silica are disclosed. The alumina support has a pore volume greater than 0.60 cc / g, a median pore size in the range of about 70 mm 3 to about 120 mm 3, a pore size distribution such that at least 90% of the total pore volume is in the range of about 20 mm 3 to about 250 mm 3, and about 40 mm 3 The above pore size distribution width is characterized. The alumina composition of the composition of the present invention exhibits a first peak mode at a pore diameter below the median pore diameter. Also provided are catalysts prepared from the alumina support, and methods of making and using the supports and catalysts. |
