Computational Fluid Dynamics Modeling of HIsarna Off-Gas System: Wall Modeling and Heat Loss Prediction

The HIsarna off-gas system wall is a cooling jacket made of cooling pipes arranged in the radial direction and in a circular pattern. Part of the off-gas system cooling pipes are isolated using a low-thermal-conductivity refractory material to protect the cooling pipe from melting and thermal stresses. During long runs and due to...

Multiparametric ultrasound and machine learning for prostate cancer localization

A cost-effective, widely available, and practical diagnostic imaging tool for prostate cancer (PCa) localization is still lacking. Recently, the contrast-ultrasound dispersion imaging (CUDI) technique has been developed for PCa localization by quantifying dynamic contrast-enhanced ultrasound (DCE-US) acquisitions. Tissue stiffness is an...

Composition based on a ferrierite and its use in a gas treatment method for reducing nitrogen oxide emissions

The invention concerns catalytic compositions comprising a zeolite and methods for reducing nitrogen oxides (NOx) using said catalytic compositions. The inventive catalytic compositions comprise a ferrierite type zeolite (FER), which has been subjected to an ion-exchange with a rare earth selected among cerium, praseodymium, samarium, terbium,...

Zeolite catalysts and their use in selective catalytic reduction of NOx

The invention is directed to catalyst compositions comprising a zeolite, as well as to processes for the reduction of nitrogen oxides (NOx) employing these catalyst compositions. The catalyst compositions of the invention comprise a zeolite of the ferrierite type (FER), which zeolite is ion exchanged with Ce, in particular Ce-H-FER and are very...

Method for preparing a composite catalyst

The invention relates to the preparation of composite catalysts consisting of a support material and a molecular sieve crystal phase that is present on the surface of the support material. The molecular sieve crystals can, as desired, be provided both on the inside and on the outside of a porous support material. With the method according to the...

Structured reactor packing and method of manufacturing same

The invention comprises a method of manufacturing a catalyst element consisting of parallel rods of catalyst-containing material, which material has been provided around a rod-shaped support through pressing in a die. The invention further relates to structured catalyst packings consisting of elements manufactured according to this method....
