  1. 26. Hydrodemetallization of Petroleum - Reaction Kinetics, Activity Decay and Long-life Catalysts

    Author : Fei-Xiang Long; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; catalyst deactivation; large pore catalyst; hydroprocessing; hydrodemetallization; fibrillar alumina support; hydrotreating; kinetics; metal porphyrin; multiresponse parameter estimation; HDM;

    Abstract : Hydrodemetallization (HDM) is an indispensable step in industrial catalytic hydroprocessing of residual oils. To develop improved HDM catalysts and reactors, a detailed knowledge of the reaction mechanisms and kinetics, and a good understanding of the mechanisms and process of the catalyst decaying are very important.
