CONVERSIONS OF SULFIDE CONCENTRATES OF CRUDE-OIL IN THE PRESENCE OF A SODIUM-CHLORIDE ALUMINUM-CHLORIDE SYSTEM

A study has been made of features of the conversions of sulphide concentrates isolated from diesel fuel of Arlansk crude oil in the presence of NaAlCl4 under relatively mild conditions (200-degrees-C, atmospheric pressure, without feeding of hydrogen). It has been established that the degree of their conversion reaches 84-91 wt.%. On the basis of mass spectrometry it has been shown that, during conversion of sulphide concentrates in the presence of NalCl4, besides reactions of hydrogenolysis of sulphides at the C-S bond, a number of successive-parallel reactions occur: cracking of hydrocarbons, alkylation and condensation of arenes. In this case the chemical structure of the sulphides has a considerable influence on the extent of hydrogenolysis reactions.
