Effect of adding nitrogen-, sulphur- and organic chlorine compounds on aromatization of hydrocarbons in the presence of platinum and platinum-rheinum catalysts
Abstract 1. A comparison was made of the sensitivity of platinum and platinum-rhenium catalysts to the action of small amounts of pyridine, thiophen and carbon tetrachloride in aromatization of hydrocarbons. 2. The action of nitride and organic halide compounds on the aromatizing activity of catalysts is contradictory to some extent; according to acid properties of catalysts and the dosage of compounds, it may be activating or deactivating in each particular case. 3. The relative sulphur resistance of platinum and platinum-rhenium catalysts on contaminating with thiophen depends on hydrogen pressure. At atmospheric pressure the deactivating effect of thiophen is about the same on both catalysts and by the action of 1·1 MPa the platinum catalyst is much more sulphur-resistant than the platinum-rhenium catalyst.
