Abstract
Arsenic is removed from a hydrocarbon containing arsenic as an impurity; e.g., shale oil, by contact with hydrogen in the presence of a contact material, such as coke, to deposit the arsenic on the contact material. The arsenic deposited on the contact material is subsequently reacted with an iron compound to produce an iron-arsenic compound suitable for disposal.
