Porous alumina bodies

Porous alumina bodies useful as catalyst support have a trimodal pore distribution. The Total Pore Volume is about 0.65 - 1.30 cc/g; 2-20% of the Total Pore Volume is in form of macropores of diameter between 10.000 and 100.000 Angstrom, 5-30% of the Total Pore Volume is in form of macropores of dia...

Zusammenfassung:	Porous alumina bodies useful as catalyst support have a trimodal pore distribution. The Total Pore Volume is about 0.65 - 1.30 cc/g; 2-20% of the Total Pore Volume is in form of macropores of diameter between 10.000 and 100.000 Angstrom, 5-30% of the Total Pore Volume is in form of macropores of diameter between 1.000 and 10.000 Angstrom, and 50-93% of the Total Pore Volume is in form of mesopores of diameter between 30 and 1.000 Angstrom. Hydrodesulfurization and demetallalization of hydrocarbon charge is effected by hydrogenation in the presence of, as catalyst, a Group VI A metal and a non-noble Group VIII metal on the trimodal alumina support.
