Abstract

The sulfur sensitivity of a monofunctional Pt/KL catalyst has been investigated. Sulfur, in the ppb range, introduced in the form of thiophene functions as a stiochiometric poison and lowers, thereby, the number of available Pt sites. Additionally, feed sulfur greatly accelerates Pt agglomeration. Pt/KL deactivation resulting from metal agglomeration primarily occurs by blockage of KL channels by 10–50 Å Pt and/or PtS particles. The sulfur sensitivity of the Pt/KL catalyst is highly dependent upon the molecular structure of the sulfur source. The order of sensitivity, at constant sulfur level, is thiophene ≫ 1,2-benzodiphenylene sulfide > propanethiol > sulfolane.
