1. method of the preparation for the porous carrier materials of supported catalyst active metal, the catalytically-active metals are suitable for hydrogenatingMake to wrap metalliferous heavy hydrocarbon fraction hydrogenation demetalization under treatment conditions, the method includesA) the extrudable oxidation titanium aluminum oxide having less than 5 weight % titanium oxide is prepared, based on the total of the oxidation titanium aluminum oxidePoidometer;

  • B) optionally, make the titanium oxide alumina peptization;

    C) the oxidation titanium aluminum oxide is squeezed out to form titanium oxide alumina extrudate;

    WithD) extrudate described in 960 DEG C -1050 DEG C of temperature lower calcination to be to obtain calcined support,Wherein;

    (i) carrier has the total pore volume of 0.7-1.2 cubic centimetre/gram,(ii) hole greater than 40% with diameter greater than 200 of the total pore volume,(iii) 30% or more of the total pore volume has 200-500 hole, and(iv) hole greater than 10% with diameter greater than 1000 of the total pore volume, andWherein the carrier includes the oxidation titanium aluminum oxide having less than 5 weight % titanium oxide, based on the oxidation titanium aluminum oxideTotal weight.
