    Sammanfattning : For complex technical systems in the electricity and pulp and paper industries, maintenance management addresses how to exploit physical assets in the most profitably way. This is a difficult task that requires taking into consideration parameters of totally different natures – e.g. LÄS MER

  4. 3. Hydrodemetallization of Petroleum - Reaction Kinetics, Activity Decay and Long-life Catalysts

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

    Sammanfattning : 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.
