    • A catalyst support is prepared from a composite comprising alumina and one or more oxides of phosphorus by forming the composite into a shaped support material having at least 0.8 cc/gm of its pore volume in pores having diameters of 0 nm (0 .ANG.) to 120 nm (1,200 .ANG.) and at least 0.1 cc/gm of its pore volume in pores having diameters of 120 nm (1,200 .ANG.) to 5,000 nm (50,000 .ANG.) and heating said shaped support material in the presence of steam at sufficient elevated temperature, steam pressure, and time period to increase the average pore diameter of said shaped support in the absence of any appreciable reduction in pore volume.A catalyst is prepared by impregnating the steam-treated support with at least one hydrogenating metal.The catalyst can be used suitably in hydrocarbon conversion processes, such as a process for the hydrodemetallization of a hydrocarbon stream containing asphaltenes and a substantial amount of metals.
    • 催化剂载体由包含氧化铝和一种或多种磷的氧化物的复合材料制成,通过将复合材料形成为直径为0nm(0安格姆)至120的孔中至少具有0.8cc / gm孔体积的成形载体材料 nm(1200 ANGSTROM),并且在直径为120nm(1,200)至5,000nm(50,000)的孔中,其孔体积至少为0.1cc / gm,并且在足够高的温度下在蒸汽存在下加热所述成形载体材料, 蒸汽压力和时间段,以在没有任何明显的孔体积减小的情况下增加所述成形支撑件的平均孔径。 通过用至少一种氢化金属浸渍蒸汽处理的载体来制备催化剂。 催化剂可以适用于烃转化方法,例如含有沥青质的烃物流和大量金属的加氢脱金属的方法。
