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 %.
