Датум издавања: | 1-јан-1997 | Часопис: | Studies in Surface Science and Catalysis | Сажетак: | The results of comparative investigation of NiO-MoO3/γ-Al2O3hydrodesulphurization (HDS) catalyst deactivation in industrial plant and laboratory conditions are presented. Structural (XRD, DRS, XPS), textural (LTNA) and morphological (SEM) characteristics were followed depending on temperature, time of treatment and the atmosphere of regeneration. Based on the mathematical models the of textural changes intensity depending on two independent variables (time, temperature) the role of these variables in catalyst sintering were estimated. The mechanism of deactivation process is proposed, pointing out critical conditions in processing and/or regeneration. Parallel investigation of CoO-MoO3/γ-Al2O3catalyst was the basis for relative stability estimation depending on the precursor type. © 1997 Elsevier Science B.V.
