Abstract
A process for purifying a hydrogen sulfide containing gas, which comprises absorbing said hydrogen sulfide onto a mass comprising zinc oxide, alumina and a group II A metal oxide, a large proportion of the group II A metal oxide being in the form of aluminate or silicoaluminate; then regenerating the mass by passing an oxygen containing gas therethrough.
