Title (EN) ENHANCED CATALYST MIXING IN SLURRY BUBBLE COLUMNS
(FR) MELANGE DE CATALYSEUR AMELIORE DANS DES COLONNES A PLATEAUX DE BARBOTAGE
Abstract: front page image
(EN)Catalyst particle distribution and mixing in the slurry part of bubble columns is improved by introducing a secondary suspending fluid into the columns at locations within the lower 20 % of the vertical height of the column (3) but above the gas distributor (2) normally located at or near the bottom of the columns.
(FR)On améliore la répartition et le mélange de particules de catalyseur dans la partie suspension de colonnes à plateaux de barbotage en introduisant un fluide de suspension secondaire dans les colonnes au niveau d'emplacements situés dans la partie inférieure correspondant au cinquième de la hauteur verticale de la colonne (3), mais au-dessus du distributeur (2) de gaz généralement situé au fond ou à proximité du fond des colonnes.
