In the treatment of shale oil 1 contaminated with particulate shale solids and metals, such as iron and arsenic, a close-coupled two-stage hydroprocessing of the oil is performed by (a) contacting the contaminated shale oil with hydrogen in a hydrothermal treating zone 5 to form a product 7 which still contains shale solids and metals, and (b) catalytically hydroprocessing the product by passing the product through a hydroprocessing zone 11 with hydrogen gas 9 in upflow relationship to the catalyst of the hydroprocessing zone. <IMAGE> |
