CA 2505607
Waxy feeds are converted to a basestock using a unitized mixed powdered pellet catalyst comprising a metal hydrogenation component on a support having a frist dewaxing component and a second isomerization component, wherein the first component is selected from 10 and 12 ring molecular sieves and mixtures thereof and the second component is an amorphous inorganic oxide. The first and second components are present in a ratio sufficient to promote wax isomerization and naphthene distractions without substantial decrease in VI.
Selon l'invention, des charges paraffineuses sont transformées en une huile de base au moyen d'un catalyseur sous forme de pastilles de poudre mixtes unitaires comprenant un composant d'hydrogénation métallique sur un support comportant un premier composant de déparaffinage et un second composant d'isomérisation, le premier composant étant choisi parmi des tamis moléculaires à 10 et 12 cycles et des mélanges de ceux-ci et le second composant étant un oxyde inorganique amorphe. Le premier et le second composant sont présents selon un rapport suffisant pour favoriser l'isomérisation de la paraffine et la destruction du naphtène sans réduction sensible de l'indice de viscosité.
