Sorption of nitrogen and benzene vapor by a tungsten sulfide catalyst

Bulletin of the Academy of Sciences of the USSR, Division of chemical science Aims and scope

Summary

  1. 1.

    We studied the sorption of nitrogen vapor at −195° and benzene vapor at 20° on unused and used industrial WS2 catalyst differing in chemical composition, which had first been evacuated at 400°.

  2. 2.

    Under the conditions of the adsorption experiments there was irreversible sorption of both nitrogen and benzene on the WS2 catalyst.

  3. 3.

    Despite the presence of irreversible sorption, the structural characteristics of the unused catalysts determined from the adsorption of benzene were close to the corresponding characteristics calculated from the adsorption of nitrogen.

  4. 4.

    From a detailed comparison of data on the sorption of nitrogen with data on the sorption of benzene it was established that the high sorption of benzene on used catalysts was caused by absorption of C6H6 by coking products present in the pores.
