Process for the manufacture of a catalyst for hydrocracking of heavy petroleum fractions |
| 摘要 |
The process for the manufacture of the catalyst consists essentially in preparing a silica-alumina gel and in adding an alumina hydrate to this gel with a view to obtaining a catalyst whose textural properties are as follows: S >/= 180 m<2> g<-1>; TPV >/= 50 cm<3> g<-1>; mPV >/= 45 cm<3>; % V75 </= 50 %; % Na2O < 0.05 % (weight). l
