Abstract: A method of synthesizing high-silica zeolites in a fluoride media using faujasite crystals as the aluminum source and quasi-siliceous seed crystals containing a small amount of germanium is described. The faujasite crystals dissolved during hydrothermal treatment, prior to the crystallization of LTA-type zeolites. High-silica zeolites of an LTA, a CHA, a *BEA and an STT-type were produced. High-silica zeolites with a Si/Al ratio (SAR) of 63 to 420 were synthesized, with the SAR related to the amount of faujasite crystals used. The aluminosilicate LTA-type zeolite products possess nearly defect-free structures, a characteristic often seen in fluoride mediated synthesis. The unit cell volumes of the high-silica LTA-type zeolites correspond to the amount of Al present in the framework. Aluminosilicate ITW-type zeolites were produced using these methods.

Abstract: The present invention provides a renewable route to para-xylene via cycloaddition of ethylene and 2,5-dimethylfuran and subsequent dehydration with high selectivity and high yields using acidic heterogeneous catalysts and a solvent for 2,5-dimethylfuran. The use of a solvent shows significant effects in the reduction of competing side reactions including hydrolysis of 2,5-dimethylfuran to 2,5-hexanedione, alkylation of p-xylene, and polymerization of 2,5-hexanedione.

Abstract: A zeolite composition CIT-1 is provided, the composition having a mole ratio greater than about 20:1 of a first oxide selected from silicon oxide, germanium oxide, or mixtures thereof to a second oxide comprising boron oxide; which zeolite composition has a specific X-ray powder diffraction pattern in accordance with Table 1 of the disclosure. In one embodiment, the second oxide may comprise mixtures of boron oxide with one or more of aluminum oxide, gallium oxide, iron oxide, titanium oxide and vanadium oxide. Also disclosed is a method for making CIT-1 zeolites comprising the preparation of an aqueous mixture containing sources of a N,N,N-trimethyl cis-myrtanyl ammonium ion, boron oxide or mixtures of boron oxide with one or more of aluminum oxide, gallium oxide, iron oxide, titanium oxide and vanadium oxide, and an oxide selected from silicon oxide, germanium oxide, and mixtures thereof. The mixture is maintained under sufficient crystallization conditions, preferably at a temperature of at least 100.
