ABSTRACT:
An improved Claus catalyst comprising activated alumina in which sodium oxide concentration is controlled to achieve increased sulfur conversion. Sodium oxide is present in an amount greater than 1.0 wt % (1100.degree. C. calcined basis), the remainder being activated alumina. Specific surface area is greater than 100 m.sup.2 /g (BET). The catalyst preferably has a surface area greater than 300 m.sup.2 /g (BET) and an LOI (hydroxyl content as determined by heating from 400.degree. to 1100.degree. C.) between 2.0 and 6.0 wt %.
