Coking and Regeneration of Al-Ni-Mo Hydrofining Catalyst Sulfidized by Tert-Butyl Polysulfide and Dimethyl Disulfide

Resumo

Coking and regeneration of a hydrofining catalyst activated by various sulfidizing agents are analyzed. The procedures for activating the catalyst in a high-pressure catalysis unit by tert-butyl polysulfide and dimethyl disulfide are described. The activation energy for catalyst regeneration by oxygen is calculated for different heating rates using differential scanning calorimetric data.
