Existing processes to improve the quality of heavy oil cuts catalytic converter hydroconversion can be mentioned in the slurry phase. This process is usually done in the temperature 440˚C to 470˚C be a heavy craking led to the production of light weight thermal feed can be more. With more products light, adverse reaction can also lead to the formation of coke be. Coke formation of secondary radical reactions can be feed from cracking of heavy compounds. Coke production is to eliminate or limit the ability of homogeneous catalysts (eg sulfide Molybdium) about 600-1000 ppm disposable food adds to be used. The main role of catalyst in the stable radicals fail thermal compound feed is heavy. The...
