  • Publication number: 20070037690
    Abstract: A process for preparing a calcined zirconia extrudate comprising the steps of: a. preparing a shapable dough which comprises mixing and kneading a particulate zirconia with a solvent to obtain a mixture having a total solids content of from about 50% to about 85% by weight, b. extruding the shapable dough to form a zirconia extrudate, and c. drying and calcining the zirconia extrudate; characterized in that the particulate zirconia comprises no more than about 15% by weight of zirconia which is other than monoclinic zirconia. The calcined zirconium extrudates prepared according to the present invention exhibit significantly improved crush strength and is suitable as a catalyst or catalyst support in a wide range of chemical processes.
    Type: Application

  • Publication number: 20060149117
    Abstract: A process for the preparation of detergents containing a relatively low amount of isoparaffins, involving separating a hydrocarbonaceous product stream from a Fischer-Tropsch process using a cobalt based catalyst and producing normally liquid and normally solid hydrocarbons into a light fraction boiling below an intermediate fraction having detergent hydrocarbons, an intermediate boiling fraction having detergent hydrocarbons and a heavy fraction boiling above the intermediate boiling fraction having detergent hydrocarbons, followed by conversion of the detergent hydrocarbons present in the intermediate boiling fraction into detergents, the Fischer-Tropsch process being carried out at a relatively high pressure.
