Abstract: A zeolite A or an A/X mixture having an LCC>70 g liquid/100 g zeolite (hydrated) and a cold water CER>200 mg CaCO3/gram anhydrous zeolite (hydrated). The zeolite product may have a crystal size of 0.1-0.7 microns, a bulk density of 0.19-0.37 g/ml, and a median particle size of 1-5 microns. A process for making zeolite A or A/X mixtures is also claimed, including mixing a sodium silicate solution, a sodium aluminate solution, and an amorphous aluminosilicate initiator gel in a mixing vessel to create an aluminosilicate synthesis gel, and crystallizing the aluminosilicate synthesis gel to form zeolite crystals. The sodium aluminate solution may be added gradually to at least the sodium silicate solution at a rate of about 1-5% of the total batch alumina per minute, and/or a percentage of the total batch alumina may be added as alumina trihydrate (ATH) powder.

Abstract: The present invention is directed towards methods for the cost-effective commercial manufacture of small crystal titanium-silicate molecular sieve products, toward a novel titano-silicate molecular sieve composition synthesized thereby, which the present inventors have termed “TS-PQ”, and toward uses of that molecular sieve composition as an oxidation catalyst.

Abstract: A hydrophobic zeolite is prepared having high Hydrophobicity Index number by calcining a zeolite with steam under turbulent condition with respect to flow pattern of the zeolite and at a temperature within the range of 650-1000° C.

Abstract: Low silica forms of faujasite-type zeolites are prepared from more siliceous forms of the same zeolite species by contacting the starting zeolite with a highly caustic concentrated sodium aluminate solution at elevated temperatures. In view of the fact that the process does not favor the formation of undesirable impurity phases such as zeolite A and thus does not require the presence of zeolite A nucleation inhibitors, the process is particularly advantageous in the production of forms of zeolite X having Si/Al.sub.2 molar ratios below 2.5.

Abstract: Difluoromethane (R32) is of current interest as a partial replacement for chlorodifluoromethane (R22) refrigerant heretofore widely used in vapor compression refrigeration systems. R32 has, however, proved to be more reactive than is desirable with the zeolite A adsorbent-desiccant compositions used in such systems to prevent corrosion and freeze-up problems. The sodium cation form of a zeolite having the crystal structure of zeolite B is found to be an effective adsorbent for that purpose and to be significantly less reactive with the R32.

Abstract: Zeolite beta is synthesized hydrothermally from an aqueous reaction mixture containing the conventional reactive sources of SiO.sub.2, Al.sub.2 O.sub.3 and Na.sub.2 O tetraethylammonium halide as the source of the crystallization directing tetraethylammonium ions and diethanolamine as the agent providing the increased basicity necessary for the formation of zeolite beta crystals. Seed crystals of zeolite beta are optionally employed to shorten the crystallization period.

Abstract: The process for the catalytic cracking of a crude oil feedstock to produce lower boiling hydrocarbons which comprises contacting said feedstock with a zeolitic aluminosilicate which has a mole ratio of oxide in the dehydrated state of (0.85-0.1)M.sub.2/n 0:11.sub.2 O.sub.3 : x SiO.sub.2 wherein M is a cation having a valence of "n"; x has a value greater than 6.0: having a X-ray powder diffraction pattern having at least the d-spacings of Table A; having extraneous silicon atoms in the crystal lattice in the form of framework SiO.sub.4 tetrahedra, wherein said aluminosilicate has been ion-exchanged with Group IIIA cations. In addition, the Group IIIA exchanged LZ-210 may be heated for an effective temperature and for effective time in the presence of an effective amount of steam, and/or may be ion-exchanged with a multivalent cation other than Group IIIA, e.g. rare earth, to provide catalyst compositions.

Abstract: The instant process relates to a process for treating fluoride-containing catalysts or aluminosilicates which contain insoluble fluoride compounds by the use of soluble aluminum compounds.

Abstract: Crystalline synthetic zeolite, denoted "LZ-200", has an anhydrous composition in terms of mole-ratios of oxides of:0.9-1.1 Na.sub.2 O: Al.sub.2 O.sub.3 :1.9-2.4 SiO.sub.2,while having a pore diameter somewhat smaller than that of potassium zeolite A, and is useful as an adsorbent and ion-exchanger.
