✦ Synopsis

The adsorption of selected sulphur compounds from rz-heptane solution on molecular sieve 13X was investigated under dynamic conditions, mainly at concentrations of the order of 0,032-l mg/ml of sulphur. Some thiophenes, sulphides and thiols likely to occur in the 50-150" gasoline cut from crude oil were submitted to adsorption.

The influence of benzene on the adsorption of selected sulphur compounds was also investigated. The sulphur compounds adsorbed on molecular sieve 13X were desorbed to n-heptane or isooctane using a hydrochloric-hydrofluoric acid" mixture to determine the degree of concentration.
