    摘要： Described herein is a process for enhancing the hydrophobicity of crystalline molecular sieves and also crystalline molecular sieve compositions which have enhanced hydrophobic character and modified catalytic properties. The crystalline molecular sieves are contacted with a silicon tetrafluoride gas mixture at a temperature from about ambient to about 200.degree. C. to alter (1) the framework aluminum and silica content, (2) the surface characteristics, and (3) the acidic sites of the molecular sieves with resulting modification of both the adsorptive properties, i.e., enhanced hydrophobicity, and catalytic properties of the molecular sieves. The crystalline molecular sieves can further undergo ion exchange to remove any aluminum fluoride cation species such as AlF.sup.++ and AlF.sub.2.sup.+. The crystalline molecular sieve compositions of this invention are useful as selective hydrophobic adsorbents and catalysts.

    摘要： Molecular sieve agglomerates exhibiting reduced pore mouth blockage and decreased diffusivity resistance to the internal sieve pores result from coating, prior to addition of a binding agent to the sieve, the molecular sieve particles with an organic polymer, fixing the polymer to the sieve surface so that it exhibits no migratory tendencies and subsequently removing the coating by combustion during calcination of the formed agglomerate. Such agglomerates showed enhanced activity and selectivity in typical refining processes such as dewaxing and fluid catalytic cracking. The molecular sieve agglomerates also may be employed in other hydrocarbon conversion processes such as hydrocracking, dehydrocyclization, isomerization, hydrofining, reforming, and dealkylation.

    摘要： A process for hydrocracking a crude oil feed, a hydrocracking catalyst employed therein, and a process for the preparation of this catalyst are disclosed. The hydrocracking catalyst comprises a zeolitic aluminosilicate which has an SiO.sub.2 /Al.sub.2 O.sub.3 molar ratio of at least 6 and which has been treated by (i) thermal treatment at an effective temperature and for an effective time in the presence of steam, followed by (ii) ion-exchange with a solution containing ammonium ion; and (2) an effective amount of a hydrogenation component. In a preferred embodiment, the starting crystalline zeolitic aluminosilicate is a Y-type zeolite having an SiO.sub.2 /Al.sub.2 O.sub.3 molar ratio of at least about 9 and a unit cell dimension (a.sub.o) of less than about 24.55 .ANG., and the steam treatment is carried out for a period sufficient to cause a decrease of not more than about 0.1 .ANG. in the unit cell dimension, thereby producing a Y-type zeolite product having a SiO.sub.2 /Al.sub.2 O.sub.3 molar ratio of at least about 9 and a unit cell dimension of less than about 24.45 .ANG..
