    Abstract: A method for generating, recording and pre-processing high fidelity vibratory seismic data in a system that uses a plurality of vibratory sources (18, 20, 22 and 24) includes the steps of measuring the motion of each of the vibrators (18, 20, 22 and 24), determining a ratio by dividing the vibratory seismic data by the measured motion of the vibrator to remove the unknown applied force leaving the earth reflectivity times a time derivative divided by a minimum phase function, minimum phase band pass filtering (54) the resulting ratio and performing minimum phase deconvolution (56) to remove the time derivative divided by the transfer function of minimum phase. The method may also include the steps of shot ensemble deconvolution (66), receiver ensemble deconvolution (72), statics correction (88), F-K filtering (70) for noise, zero phase spiking deconvolution (74) and model dephasing (76). The vibrator motion is measured to provide a signal that is used to process the data. The data is divided by the relative of the actual transmitted signal in frequency domain.

    Abstract: An ethylene-alpha-olefin copolymerization catalyst is prepared by impregnating a porous support, such as silica, with a contact mixture of an organomagnesium compound such as dialkyl magnesium and a silane compound which is free of hydroxyl groups, such as tetraethyl orthosilicate. A transition metal component such as titanium tetrachloride is then incorporated into the support in a specific ratio to the magnesium and silane components. Activation of this catalyst precursor with a trialkylaluminum compound results in a catalyst system which is effective for the production of ethylene copolymers.

    Abstract: A process for the net catalytic oxidative dehydrogenation of alkanes to produce alkenes is provided. The process involves simultaneous equilibrium dehydrogenation of alkanes to alkenes and combustion of the hydrogen formed to drive the equilibrium dehydrogenation reaction further to the product alkenes. In the present reaction, the alkane feed is dehydrogenated over an equilibrium dehydrogenation catalyst in a first reactor (110) and the effluent, along with oxygen is then passed into the second reactor (120) containing a metal oxide catalyst which serves to selectively catalyze the combustion of hydrogen. The equilibrium dehydrogenation catalyst may comprise platinum and the selective metal oxide combustion catalyst may contain bismuth, antimony, indium, or molybdenum, or a mixture thereof.

    Abstract: This invention discloses a process for producing a high Viscosity Index lubricant having a VI of at least 125 from a waxy hydrocarbon feed having a wax content of at least 40 wt.%. The process comprises catalytically dewaxing waxy paraffins present in the feed by isomerization in the presence of hydrogen and in the presence of a low acidity large pore zeolite isomerization catalyst. This catalyst has a ratio of SiO2/Al2O3, as synthesized, of at least 200:1, wherein the catalyst is prepared in the absence of boron. The feed may be hydrocracked prior to dewaxing with the large pore zeolite. The effluent of the process may also be further dewaxed by either solvent or catalytic means in order to achieve target pour point.

    Abstract: A heavy aromatics feed is converted to lighter aromatics products, such as benzene, toluene and xylenes by contacting a C9+ aromatics fraction and benzene and/or toluene over a catalyst comprising a zeolite, such as ZSM-12, and hydrogenation component, preferably platinum. The catalyst, complete with hydrogenation component, is treated to reduce aromatics loss. Treatment includes exposure to steam and/or sulfur after incorporation of the hydrogenation component. For additional stability and aromatics retention the steamed and/or sulfur treated catalyst is sulfided by cofeeding a source of sulfur. A low hydrogen partial pressure is preferably employed to assist in aromatics retention.
