UPGRADING OF FISCHER-TROPSCH HEAVY END PRODUCTS

High silica to alumina ratio zeolite beta modified with boron, tin, lead or indium and combined with a hydrogenation/dehydrogenation component is used to convert Fischer-Tropsch heavy end products which may contain paraffins, olefins and oxygenates into low pour point distillates with high cetane nu...

More Information
Summary:High silica to alumina ratio zeolite beta modified with boron, tin, lead or indium and combined with a hydrogenation/dehydrogenation component is used to convert Fischer-Tropsch heavy end products which may contain paraffins, olefins and oxygenates into low pour point distillates with high cetane number and extra high VI lube is described. The lube can be dewaxed by a conventional solvent process, by a catalytic process, or by increasing the severity of the hydroisomerization step. L'invention se rapporte à la zéolite bêta à rapport silice/oxyde d'aluminium élevé modifiée, à l'aide de bore, d'étain, de plomb ou d'indium et combinée à un composant d'hydrogénation/déshydrogénation. Ladite zéolite est utilisée pour convertir des produits finis lourds obtenus selon le procédé Fischer Tropsch, pouvant contenir des paraffines, des oléfines et des matières oxygénées, en distillats à faible point d'écoulement présentant un indice de cétane élevé et contenant un lubrifiant de classe VI supérieure. On peut déparaffiner le lubrifiant par un procédé conventionnel au solvant, par un procédé catalytique, ou par intensification de la vivacité de la phase d'hydroisomérisation.
