Effect of sulphur compounds on dehydrogenation of n-dodecane in the presence of an alumina-chromium-potassium catalyst
Abstract 1. A study was made of the effect of elementary sulphur, hydrogen sulphide, thiophen and diethyldisulphide additives (sulphur concentration 0·0006–0·01%) on dehydrogenation of n-dodecane containing 0·0005% total sulphur, in the presence of an alumina-chromium-potassium catalysts (500°C; 0·4 MPa, space velocity 40 hr−1, molar dilution with hydrogen 8) in experiments taking up to 6 hr. 2. It was shown that thiophen already in a concentration of 0·0006% S and elementary sulphur, hydrogen sulphide and diethyldisulphide in a concentration of 0·007–0·01% S have a toxic effect on the catalyst, reducing its activity and selectivity, the toxic effect depending on the type of sulphur compound. Catalyst activity may be restored by oxidizing regeneration.
