摘要
A process is described for the production of middle distillates from a paraffinic feedstock wherein the feedstock is subjected to hydrocracking and/or hydro-isomerization in the presence of a hydrocracking/hydro-isomerization catalyst. The catalyst comprises at least one hydro-dehydrogenating metal selected from metals of groups VIB and VIII, and a substrate that comprises at least one dealuminified Y zeolite. The dealuminified Y zeolite is modified by a basic treatment stage wherein the dealuminified Y zeolite is mixed with a basic aqueous solution, and at least one heat treatment stage.
