    摘要： Spheroidal alumina particulates having bifold porosity are prepared by (i) intimately admixing, at a pH of less than about 7.5, (a) a sol of a member selected from the group consisting of ultrafine boehmite and pseudo-boehmite, said sol being devoid of amorphous alumina and the concentration by weight thereof, in content by weight of Al.sub.2 O.sub.3, being between 5 and 25%, with (b) from 30 to 95% by weight, based upon the total solids content of the admixture, of spheroidal alumina particulates essentially completely in at least one of the phases eta, gamma, delta and theta, such particulates having a micropore volume ranging from about 0.4 to 1 cm.sup.3 /g, a specific surface ranging from about 100 to 350 m.sup.2 /g, and particle diameters ranging from about 1 to 50 microns; (ii) prilling said intimate admixture into spheroidal particulates and gelling the same; and then, (iii) recovering, drying and calcining said gelled particulates at a temperature of from 550.degree. to 1100.degree. C.The resultant particulates having bifold porosity are useful as catalysts or catalyst supports.

    摘要： Spheroidal alumina shaped articles are prepared by dispersing an ungelled admixture of an alumina sol and hexamethylenetetramine, in the form of droplets, into a liquid forming medium which is but very slightly miscible with water, said medium being at a temperature of between about 50.degree. and 105.degree. C., next aging the alumina spheres thus shaped at a temperature greater than about 105.degree. C. at superatmospheric pressure, then secondarily aging said alumina spheres in a basic medium, and thence washing, drying and calcining said aged alumina spheres.The resultant shaped articles are useful, e.g., catalysts or catalyst carriers/supports.

    摘要： Type Y zeolites were adopted as, e.g., catalysts and adsorbents, are facilely prepared by (i) intimately admixing, at essentially ambient temperature, an aqueous solution of a water-soluble aluminum compound with an aqueous solution of sodium silicate as to prepare a reaction mixture solution or sol therefrom, (ii) next heating said reaction mixture solution or sol to a temperature of crystallization, ranging from about 50.degree. to 120.degree. C., by heat exchange within such rapid period of time as to avoid any phase conversion thereof, but whereafter said reaction mixture solution or sol transforms essentially immediately into a gel, and (iii) thence maintaining the resulting gel at such crystallization temperature until Type Y zeolite crystals are crystallized therefrom.
