Characterization of abundant ''heavy'' feedstocks such as tar sands, heavy oils and vacuum residua will play a fundamental role in the use of these energy sources. Their physical and chemical properties vary from one feed to another, and this can have some consequences in their necessary upgrading processes. In this paper results on the characterization of 510/sup 0/C-vacuum residua (VR) obtained from Venezuelan Heavy and Medium Oils are presented. These are Morichal (Mo), Merey (Me), Guafita (Gu) and Barinas (Ba). The VR have all an API gravity between 3 and 6, more than 15% asphaltenes, metals above 200 ppm, as well as high contents of nitrogen, more than 6000 ppm, and sulphur, over 1%. It has been found that when these feeds are hydrotreated under similar conditions the processability improves in the order Ba
