Simple tests determine catalyst regeneration temperature.(oil refining research)(Brief Article)

Laboratory results from thermogravimetric analysis (TGA) and derivative thermal analysis (DTA) were used to determine the temperature range for regeneration of a commercial hydrodesulfurization catalyst.

Further testing of this catalyst after three cycles of use and regeneration shows good activity.

The technique and commercial results were described by Stephen Murff of Eurecat U.S. Inc., Pasadena, Tex., at Oil & Gas Journal's International Catalyst Conference & Exhibition, Feb. 1-2, Houston.

Laboratory testing

A spent sample of CoMo hydrodesulfurization catalyst was thermally analyzed using the TGA and DTA techniques (Fig. 1). The experiment was …
