Abstract
Arsenic can be continuously removed from shale oil by passing the shale oil through a first guard bed containing catalyst capable of substantially reducing the arsenic content of the oil, until the desired amount of arsenic is removed. The flow of the shale oil is thereafter directed to an intercommunicating second guard bed containing another or similar catalyst capable of substantially reducing the arsenic content of the oil. Concurrently, the spent catalyst in the first bed is regenerated in situ so that continuous upgrading of the shale oil is achieved.
