Zusammenfassung: | The instant invention is directed to the preparation of a slurry catalyst composition. The slurry catalyst composition is prepared in a series of steps, involving mixing a Group VIB metal oxide and aqueous ammonia to form an aqueous mixture and sulfiding the mixture to form a slurry. The slurry is then promoted with a Group VIII metal. Subsequent steps involve mixing the slurry with a hydrocarbon oil, and combining the resulting mixture with hydrogen gas (under conditions which maintain the water in a liquid phase) to produce the active slurry catalyst.
La invencion actual se dirige a la preparacion de una composicion de catalizador en suspension. La composicion de catalizador en suspension se prepara en una serie de etapas, que involucran mezclar un oxido de metal del Grupo VIB y amoniaco acuoso para formar una mezcla acuosa y sulfurar la mezcla para formar una suspension. La suspension luego se promueve con un metal del Grupo VIII. Las etapas posteriores involucran mezclar la suspension con un aceite de hidrocarburos, y combinar la mezcla resultante con gas hidrogeno (bajo condiciones las cuales mantienen el agua en una fase liquida) para producir el catalizador activo en suspension. |
