    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..

    摘要: Catalytic cracking catalysts, the process of their preparation and the process of their use. The cracking catalyst comprises a zeolite having a mole ratio of oxides in the dehydrated state of (0.85-1.1) M.sub.2/n O:Al.sub.2 O.sub.3 :xSiO.sub.2 wherein "M" is a cation having a valence of "n", "x" has a value greater than 6.0, has a x-ray powder diffraction pattern having at least the d-spacings of Table A, has extraneous silicon atoms in the crystal lattice in the form of framework SiO.sub.4 tetrahedra and has been thermally treated and/or cation exchanged with a multivalent cation. The catalyst of the instant invention are unique in the fact that the zeolitic aluminosilicate has less than 1.2 weight percent Na.sub.2 O and such is achieved without the requirement of a pre-calcination step.

    摘要: A vehicular atmosphere cleansing system utilizes a regenerative wheel having flow channels extending through the wheel coated with an adsorbant. An atmosphere stream passes through a first position dependent portion of the wheel where VOC's including HC's are adsorbed while a heated atmosphere stream passes through a second position dependent regenerative portion of the wheel whereat VOC's are desorbed. The adsorbant is activated carbon having particles of micropore size adhered to the substrate by a silicone binder producing high adsorption efficiencies while withstanding relatively high regenerative heat temperatures resulting from exhaust gas sensible heat. A hydrocarbon senses HC in the desorbed heated atmosphere stream to rotatively and sequentially index pie shaped, segmented portions of the wheel into the wheel's regenerative region while also functioning as the main component of an OBD device for the system.
