IMPROVED PROCESS FOR THERMALLY CONVERTING HEAVY PETROLEUM FRACTIONS AND REFINING RESIDUES IN THE PRESENCE OF OXYGEN COMPOUNDS OF SULFUR, NITROGEN OR PHOSPHORUS

摘要

A PROCESS FOR THE THERMAL CONVERSION OF VARIOUS FOSSIL ORGANIC MATERIALS SUCH AS HEAVY CRUDE OILS, HEAVY CUT-OFFS OR REFINING RESIDUES. PRESENCE OF A MINOR PROPORTION OF AT LEAST ONE OXYGEN COMPOUND GENERATOR OF RADICALS, CONTAINING AT LEAST ONE HETERALLY CHOSEN FROM SULFUR, NITROGEN AND PHOSPHORUS AND IN WHICH OXYGEN IS CARRIED BY IT HETERALLY. /P P APPLICATION TO THE PETROLEUM AND COAL INDUSTRY AND ESPECIALLY TO THE HYDROVISCOREDUCTION PROCESS.
