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.

Abstract: This invention relates to a process for separating and isolating olefins from saturated hydrocarbons, and in particular, to a process for separating and isolating olefins from saturated hydrocarbons in a Fisher-Tropsch stream.

Abstract: A process for the production of hydrocarbons from gaseous hydrocarbonaceous feed involving the steps of: i) partial oxidation conversion of the gaseous hydrocarbonaceous feed and oxygen containing gas at elevated temperature and pressure into synthesis gas; ii) catalytical conversion of synthesis gas of step i) using a cobalt based Fischer-Tropsch catalyst into a hydrocarbons comprising stream; iii) separating the hydrocarbons comprising stream of step ii) into a hydrocarbons product stream and a recycle stream; and, iv) removing carbon dioxide from the recycle stream and recycle of carbon dioxide depleted recycle stream to step i).

Abstract: Process for the preparation of an alkoxylated alcohol composition comprising one or more alkoxylated alcohols wherein the process comprises the steps of: (a) reacting carbon monoxide with hydrogen under Fischer-Tropsch reaction conditions in the presence of a Fischer-Tropsch catalyst; (b) separating from the product of step (a) at least one hydrocarbon fraction comprising paraffins having from 9 to 17 carbon atoms and olefins having from 9 to 17 carbon atoms, the hydrocarbon fraction additionally comprising at least a portion of alcohols; (c) contacting one or more of the hydrocarbon fractions obtained in step (b) with an alkylene oxide; and (d) recovering an alkoxylated alcohol composition from the reaction product of step (c).

Abstract: A process for separating linear alpha olefins from a feedstock containing linear alpha olefins, saturated hydrocarbons, internal olefins, branched olefins, and alcohols, in particular, from a Fisher-Tropsch stream is provided.
