  • Patent number: 11932711
    Abstract: The invention relates to a method for producing a hydrocarbon resin, in which method a monomer mixture which contains an aromatic component containing indene and/or C1-4 alkylindene and a cyclic diolefin component containing a cyclic diolefin compound is polymerized by heating to a polymerization temperature of at least 180° C. to obtain a product stream containing hydrocarbon resin, wherein oligomers which contain units originating from the cyclic diolefin compound and/or units originating from the aromatic component are separated from the product stream and returned to the monomer mixture, and wherein the hydrocarbon resin is heated in an annealing step to a temperature of 150° C. to 300° C. for a period of 15 minutes to 240 hours. The invention also relates to a hydrocarbon resin that is obtainable by the method, to a hydrogenated hydrocarbon resin, and to the use of the hydrocarbon resin and the hydrogenated hydrocarbon resin.

  • Patent number: 8613801
    Abstract: In a continuous method for production of a semicoke powder with high bulk density and flowability, a sinterable carbon powder (semicoke) is dispersed in water with addition of at least one binder and at least one liquefier, wherein the proportion of carbon in the dispersion is adjusted to at least 50 wt. %, relative to the mass of the dispersion, and the zeta potential of the dispersion is adjusted to less than ?50 mV, the dispersion is submitted to homogenization and stabilization by continuous wet grinding with a residence time in the mill of less than 3 minutes and the homogeneous dispersion is spray-dried.
