Definitions

  • the present invention relates to a ternary fuel with a substantially constant acetylene content in the liquid and vapor phases.
  • the more volatile component than acetylene is ethylene.
  • the third constituent chosen so as to bring about the stabilization of the liquid phase is a hydrocarbon the molecule of which contains three carbon atoms, the said hydrocarbon being part of the group consisting of propane, cyclopropane and propylene and the choice preferably being carried on the unsaturated hydrocarbon.
  • the ternary fuel with a substantially constant content of acetylene, ethylene and a hydrocarbon containing three carbon atoms in its molecule contains 15 to 25% by volume of acetylene, 5 to 17% by volume of C 3 hydrocarbon and the complement to 100 by ethylene.
  • the ethylene / C 3 hydrocarbon molar ratio is preferably between 6 and 12.
  • the fuel mixtures of the invention when the C 3 hydrocarbon is propylene are represented in the ternary diagram annexed to FIG. 1.
  • the contents of acetylene, ethylene and propylene are given in percentages by volume.
  • the acetylene consistency properties of the compositions are substantially converted in the ABCD quadrilateral and more particularly in the FGHI limited quadrilateral. both the C 2 H 4 / C 3 H 6 ratio between 6 and 12.
  • the preferred field of use corresponds to a mixture containing approximately 20% by volume of acetylene, approximately 10% by volume of propylene and approximately 70% by volume of ethylene, represented by the point E in the quadrilateral ABCD.
  • the points E '"and E" correspond respectively to the compositions of the liquid E "' and gaseous E phases" of the mixture E at 70% drainage;
  • line EE '" represents the evolution of the liquid phase E, line E'E" that of the gas phase E;
  • the conjugate point E ' corresponds to the composition of the gas phase in equilibrium with E.
  • the ternary combustible mixtures have a very great storage flexibility, they can in particular be stored in cryogenic containers, at a temperature between -80 ° and -60 ° C and under pressure from 3 to 6 bars.
  • Figure 2 corresponds to the composition of the liquid phase during emptying and Figure 3 corresponds to the variation of the composition of the gas phase during the same emptying.
  • Mixtures 2 and 3 were produced whose volume compositions of the initial liquid phases are: and made comparisons with ethylene and the mixture with 20% acetylene and 80% ethylene, known under the trademark "Crylene".
  • FIG. 4 shows the evolution of the flame temperatures as a function of the richness (R) plotted on the abscissa, the maximum is observed for richnesses close to 1.3; temperatures in degrees centigrade (T ° C) being plotted on the ordinate axis.
  • mixtures 2 and 3 have temperatures close to "Crylene", the mixtures of the invention form a group close to "Crylene".
