Microscopic Imaging of Porous Media With X-Ray Computer Tomography

Abstract: This paper presents a new method for imaging the 3D microstructure of porous media The method is based on high-resolution X-ray computer tomography (CT) where a cone-shaped, diverging X-ray beam is used to generate 2D transmission images Unlike traditional X-ray CT, a 3D reconstruction array is created directly instead of creating a series of 2D slices This allows direct measurement of 3D geometric and topologic properties of porous media on a microscale The authors results also demonstrate the effectiveness of the high-resolution system for imaging the distribution of two fluid phases in the void space The imaging system overcomes the limitations of current methods and has enormous potential for quantifying the microstructure of chaotic porous media

Fcc catalyst section control

Abstract: In the fluid catalytic cracking process, improved adaptive behavior of the catalyst section with the regenerator operating in the complete CO-burning mode is achieved by including, as elements of control, variable preheat of the air feed and variable recycle of regenerated catalyst to spent catalyst. In response to excursions of the regenerated catalyst temperature, such as would be caused by change of feedstock, the air preheat temperature and recycle ratio are altered in a direction to restore the regenerated catalyst temperature to a predetermined value. The improved control system extends the useful control range, and it also diminishes counterproductive changes in severity induced by disturbances such as change of feedstock quality.

Process for the regioselective conversion of aromatics to para-disubstituted benzenes

Abstract: Processes for converting a wide variety of aromatic hydrocarbons, such as polyalkylaromatics, into commercially useful para-substituted aromatics such as para-xylene are disclosed. The aromatic hydrocarbon feed stream is first partially converted into toluene which is then subjected to a highly para-selective methylation process. The present invention therefore provides novel processes and catalysts for increasing the para-selectivity in the selective production of para-substituted aromatic compounds. From the description provided herein, those skilled in the art will appreciate that the catalysts and processes of the present invention provide greater para-selectivity at conversion rates unattained by previously known methods.

Noble metal-containing catalysts

Abstract: A process is disclosed for preparing a noble metal-containing zeolite catalyst of high noble metal dispersion. The process of crystallizing a zeolite from a forming mixture which contains an organic template, treating the zeolite by calcining or chemical oxidation to remove the template from the zeolite, mulling the zeolite with an inorganic oxide binder and a noble metal-containing solution, and thereafter extruding the blended mixture.

Liquid holding packaging tray

Abstract: Disclosed is a packaging tray having a bottom construction which contains molded cells shaped and dimensioned to hold liquids by capillary action. The cells capture and retain liquids and prevent their free flow about the tray bottom. The bottom preferably also contains at least one upstanding raised area for holding foodstuffs away from the cells to prevent the foodstuff from breaking the surface tension of liquids retained in the cells, thus helping to ensure retention of liquids by the cells.
