    摘要: A process for the thermal conversion of various fossil organic materials such as heavy crude oils, heavy petroleum fractions or refining residues, is described. According to the invention, the charge is subjected to thermal processing in the presence of a minor proportion of at least one radical-generating monooxygenated compound, containing at least one heteroelement selected from sulfur, and nitrogen and in which the oxygen is borne by said heteroelement. The conversion is improved with a composition comprising a hydrogen donor diluent and this monooxygenated compound in a weight ratio of 0.2:1 to 400:1. The invention is useful in the petroleum industry and the coal industry and particularly in the process of hydrovisbreaking.

    摘要: Disclosed are polymers of average molecular weight ranging from 400 to 20,000 comprising thiosubstituted groups per molecule and resulting from the reaction, in the presence of an addition catalyst, of at least one compound with a thiol function, having 1 to 60 carbon atoms per molecule, with an unsaturated polyester resulting from the condensation of an aliphatic epoxide with an unsaturated aliphatic dicarboxylic compound comprising at least one ethylenic unsaturation in the alpha position of one of the carboxyl groups. Also disclosed are middle distillate compositions having a distillation range from 150.degree. to 450.degree. C. and comprising a minor proportion, preferably from 0.001 to 2% by weight, of at least one of the polymers defined hereinabove.
