  • Process for the thermal treatment of hydrocarbon charges in the presence of additives which reduce coke formation
    Patent number: 4756819
    Abstract: This invention concerns a process for the thermal treatment of hydrocarbon charges having a high content of asphaltenes in the presence of additives which prevent coke formation. The additive according to the invention is a salt of a metal selected from V, Mo, Cr, W, Fe, Co and Ni at a concentration between 100 and 2500 ppm of metal relative to the charge either in the form of a suspension of solid particles, in solution or as an emulsion. These additives prevent the coke formation in all thermal treatments of which the temperature is above about 420.degree. C., such as viscoreduction or hydro viscoreduction.
