Abstract

Decomposition of ethanethiol, diethyl sulfide and thiophene on Y zeolites modified with ammonium and alkali metal cations as well as on dealuminated Y and ZSM-5 zeolites was studied by means of GC analysis. The acidity of zeolites was measured using TPD/MS of ammonia or pyridine and a test reaction. The influence of the nature of the alkali metal cations on the strength of neighbouring acidic hydroxyls was determined. The catalytic studies have shown that the nature of the alkali metal cation and the strength of Brønsted acid centres strongly influence the activity and selectivity in ethanethiol and diethyl sulfide conversion. Thiophene did not decompose on M^IY and ZSM-5 zeolites. Its transformation required the presence of strong Brønsted acid centres and large pore zeolites.
