    摘要： A process for reducing NOx emissions and an FCC process using same as a flue gas cleanup stage are disclosed. Gas containing NOx and entrained catalyst fines is passed up through a bed of catalyst at a sufficient velocity to expand and fluidize the catalyst bed. Particulates deposited on the catalyst are abraided or elutriated away by fluidization, preventing fouling of the DeNOx catalyst. A low pressure drop design, with vertical, perforate gas distributors covered by the bed is also disclosed.

    摘要： A process for the isomerization of C.sub.4 and higher molecular weight hydrocarbons, preferably C.sub.4 to C.sub.6 paraffins with high C.sub.6 cyclics content. A C.sub.5 to C.sub.6 hydrocarbon stream is isomerized in a first isomerization reaction zone and a C.sub.4 hydrocarbon stream is isomerized in a second isomerization reaction zone. At least one or both of the effluent streams from the first and second isomerization zones are conveyed to a gas-liquid separator which separates a hydrogen-rich recycle stream. At least a portion of the hydrogen-rich recycle stream is conveyed to the C.sub.5 to C.sub.6 hydrocarbon feed stream and at least a portion of the hydrogen-rich recycle stream is conveyed to the C.sub.4 hydrocarbon feed stream whereby the hydrogen recycle stream is shared during both the C.sub.4 isomerization reaction and the C.sub.5 to C.sub.6 isomerization reaction. The product stream is conveyed to a shared stabilizer which removes the gaseous and volatile components. The product stream can be fractionated to recover the separate C.sub.4 to C.sub.6 isoparaffins and normal paraffins and naphthenic compounds.

    摘要： The endothermic heat of reaction for zeolite-catalyzed paraffin aromatization is provided by a co-fed oxygenate stream. Advantageously, the addition of a dehydrogenation metal to the zeolite reduces the reaction temperature for paraffin aromatization to a range suitable for the exothermic conversion of an oxygenate to C.sub.5 + gasoline. Preferred paraffinic feedstreams include C.sub.3 -C.sub.4 LGP and the preferred oxygenate is methanol.

    摘要： The present invention describes improved FCC and TCC stripper operations by incorporating a stripper operated at a reduced pressure. The improved strippers of the invention will increase total liquid hydrocarbon yield while reducing the coke load on the regenerator. Novel porous TCC bead catalysts are disclosed wherein at least 1/3 of the pore volume of catalyst pores having a pore diameter of at least 3000 Angstroms. These macropores facilitate flash vaporization of hydrocarbons in a stripping zone of the spent catalyst upstream of a regeneration zone.

    摘要： Hydrocarbons are processed in a co-current flow packed catalyst bed reactor containing one or more redistribution means, e.g., redistribution screens, in the packed catalyst bed. If more than one redistribution means are used, they are spaced within the bed of catalyst over a predetermined distance. Optionally, the surface area of the redistribution means is less than the cross-sectional surface area of the reactor bed to allow for packing of a relatively smaller size solid particles, as compared to the rest of the catalyst in the bed, in the area between the edge of the redistribution means and the inner wall of the reactor means. The use of the redistribution means prevents channeling of the reactants near the reactor wall region, and assures uniform distribution of the reactants throughout the packed catalyst bed. The invention is applicable to relatively low velocity systems operating at liquid linear velocity of 0.3 cm/sec. or less.

    摘要： A system and method of concentrating spent caustic at a refinery has a multi-stage flash drum for separating a spent caustic stream into an overhead output stream including vaporized water and volatile organic compounds, and a concentrated spent caustic output stream. The system also has a condenser for condensing the overhead output stream, and a separator for separating the condensed overhead output stream into a volatile organic compound stream, a liquid hydrocarbon stream and a water stream. The system further has an ejector for applying a vacuum to the flash drum to vaporize the spent caustic stream at a reduced temperature, and to the separator to remove the volatile organic compound stream. The volatile organic compounds are removed from the overhead of the separator through the ejector to a burner of a fired heater.
