Now and since several years, the availability of motor fuels and raw petrochemicals is the major concern for the world. The decrease of crude oil reserves and the increase of crude oil consumption, especially in new developed countries lead to much more expensive oil for the costumers and make more obvious the necessity to use every atoms of carbon for the most noble applications which are in the fields where there is no other alternate to this raw materials: motor fuels and raw materials for petrochemicals. Therefore in the dilemma in resids and heavy oils conversion, between carbon addition and hydrogen addition, it becomes more and more obvious that hydrogen addition is the most appropriate route. Then hydrotreating processes are the keys for delivering clean fuels and petrochemicals basis to the market. This presentation will review all existing processes to convert resids and heavy oils into distillates, including thermal and physical processes like coking and solvent deasphalting. Then we will present extensively the full range of hydrotreating technlogies: 1).slurry processes, 2). ebullated technologies, 3). moving bed technologies, 4). fixed bed and mixed technologies. In the final part of the presentation we will present integration of these hydrotreating technologies with other technologies to get the most efficient and most economical solution to produce highest yields of cleans distillates.
