摘要： The present invention relates to a process for the synthesis of overbased additives obtained by carbonation under constant pressure of carbon dioxide, the process consisting of carbonating a reaction mixture comprising a derivative of an alkaline-earth metal and at least one surfactant in a diluent oil and a hydrocarbon solvent in the presence of an oxygeneous accelerator and a nitrogeneous accelerator, while maintaining a constant pressure of carbon dioxide above the reaction mixture, the carbon dioxide is thus progressively introduced as it is consumed, thereby allowing its concentration in the liquid medium not to become too high which could thereafter provoke the formation of insoluble over-carbonated products, the reaction to be self-controlled and to obtain excellent yields of overbased products having very high alkaline values and alkaline-earth contents, while however remaining fluid and stable.

摘要： Industrial fuels comprised of mixtures of asphaltenic heavy hydrocarbon fractions and light fractions are provided wherein the flocculation of asphaltenes is minimized by the addition of from 50 to 5000 ppm of an additive composed of a constituent A and/or a constituent B to render the composition homogeneous and stable. Constituent A results from the condensation of a linear N-alkyl polyamine with a cyclic anhydride and constituents B results from the reaction of an ethoxylated amine with a carboxylic acid of C.sub.8 to C.sub.30.

摘要： A self-lubricating fuel composition is provided formed from powdered coal, a hydrocarbon fraction, water, a surfactant and a strong electrolyte. This composition develops a lubricating layer between the mechanical parts in relative movement with respect to the fluid and the fluid. Such self lubrication causes a reduction of the friction and consequently of the pressure losses during transport in ducts.
