摘要： Y Zeolites are prepared with rare earth cations and Group VIII metal cations exchanged thereinto, such zeolites being especially useful in hydrocracking catalysts. The zeolites of the invention are prepared by exchanging a sodium Y zeolite with cations of one or more rare earth elements followed by a calcination, an ammonium ion exchange, and a Group VIII metal cation exchange. The resultant zeolite is not only highly active for catalytically promoting hydrocracking reactions but is also, after use in hydrocracking environments resulting in coke deposition, essentially completely regenerable by combustion of the coke.

摘要： Waxy shale oil feeds containing organonitrogen and/or organosulfur components are contacted with a catalyst comprising a Group VIB metal component on a support containing silicalite and a porous refractory oxide under conditions of elevated temperature and pressure and in the presence of hydrogen so as to simultaneously reduce its pour point and its organosulfur and/or organonitrogen content.

摘要： Siliceous zeolite catalysts comprising zeolitic mono- and/or divalent metal cations and a non-zeolitic Group VIII noble metal hydrogenating component supported thereon, which catalysts have undergone damage by thermal and/or hydrothermal stresses resulting in a maldistribution of the metal components, are rejuvenated in activity by treatment with an aqueous ammonia solution. The treatment has a twofold effect of exchanging out at least a portion of the zeolitic mono- and/or divalent metal ions, and bringing about a desirable redistribution of the Group VIII noble metal.

摘要： Hydrocarbon conversion methods employing unique catalyst compositions exhibiting improved conversion characteristics particularly as regards denitrogenation and/or cracking selectivity to predetermined boiling range products involve the use of a catalytic combination of zeolitic aluminosilicates, alumina, and at least one of the metals, oxides and sulfides of Periodic Groups VI and VIII, prepared by the method including the steps of thermally activating at least a major portion of the alumina at a temperature of at least about 600.degree. F prior to combination with both the aluminosilicate and the hydrogenation component, forming an aggregate from an intimate admixture of the alumina, aluminosilicate and hydrogenation component and thermally activating the resultant aggregate. Midbarrel hydrocracking processes of higher selectivity and superior denitrogenation methods are described.

摘要： In an acoustic impedance meter used for evaluating the performance of the middle ear and tympanic membrane system; a sound source is coupled to the ear canal by means of an ear probe and a sound sensor in conjunction with an inverse feedback system maintains a constant sound intensity in the ear canal regardless of ear canal compliance. An analog voltage, derived from the sound source excitation, is thereby representative of ear canal compliance. A pump is provided to moderately pressurize or evacuate the ear canal to determine the variation in compliance under various test pressures. An acoustic stimulus generator may be used to elicit an acoustic reflex response and a storage and comparison circuit derives an analog voltage representative of this acoustic reflex response.
