Abstract

The present invention describes a process for the simultaneous removal of arsenic and sulphur compounds from hydrocarbon streams of fossil origin, wherein hydrocarbon streams of fossil origin resulting from the retorting process of schist are purified by direct contact with hydrated iron oxide, such as goethite (α-FeOOH) in its raw natural form (limonite ore particles).
