Abstract
A catalyst assisted upgrading process for treating a hydrocarbon oil feed to reduce total acid number (TAN) and increase API gravity is provided herein which employs a hydroprocessing catalyst based on a catalyst support, e.g., alumina. The process includes blending the supported hydroprocessing catalyst with the hydrocarbon oil feed to form a slurry which is then treated with hydrogen at moderate temperature and pressure in, for example, a tubular reactor. Deposit formation is thus minimized or avoided.
