    • An amorphous aluminosilicate sol with uniform size particles and a porous amorphous aluminosilicate powder are useful as catalyst in petroleum cracking. Water is removed from the sol without gelling so that the particles become uniformly packed into aggregates having pores of substantially uniform size and coating said powder with a surface layer 0 to 15% by weight of a metal or metal oxide, said powder having a specific surface area of 30 to 750 m.sup.2 /g, a bulk density of 0.5 g/cc or more and substantially uniform size pore diameters of from 20 A to 250 A, with pore diameters of 20 A to 45 A having a uniformity such that at least 90% of the pore volume is made up of pores of from 0.6D to 1.4D and pore diameters of 45 A to 250 A having a uniformity such that at least 80% of the pore volume is made up of pores of from 0.6D to 1.4D, where D is the median pore diameter.
    • 具有均匀粒度的无定形硅铝酸盐溶胶和多孔无定形硅铝酸盐粉末可用作石油开裂中的催化剂。 从溶胶中除去水分而不凝胶化,使得颗粒均匀地填充到具有基本均匀尺寸的孔的聚集体中,并用0至15重量%的金属或金属氧化物的表面层涂覆所述粉末,所述粉末具有比表面积 30至750m 2 / g的面积,体积密度为0.5g / cc或更大,孔径大致均匀的尺寸为20A至250A,孔径为20A至45A,均匀度为至少90 孔体积的%由0.6D至1.4D的孔隙和45A至250A的孔径组成,具有使孔至少80%的孔体积为0.6D至1.4的孔的均匀性 D,其中D是中值孔径。
