Abstract: A pitch product having a petroleum-derived distillation residue and a coal tar-derived distillation residue, said pitch product characterized by a concentration of at least 84% asphaltenes (SARA). Further, the present invention is directed to a pitch binder including said pitch product useable in manufacturing of graphite electrodes for electric arc furnaces, and carbon anodes and Soederberg paste for aluminum production. The present invention is further directed also to a graphite electrode having said pitch binder, as well as to a carbon anode comprising said pitch binder. The present invention also provides a process for producing a pitch product including a petroleum-derived distillation residue and a coal tar-derived distillation residue, said process including a petroleum vacuum distillation process step for obtaining said petroleum-derived distillation residue, and a process for manufacturing a graphite electrode or a carbon anode including said process for producing a pitch product.

Abstract: Presented and described is a hydrocarbon resin obtainable by thermal polymerization of a cyclic diolefin component including a cyclic diolefin compound with an aromatic component including indene and/or C1-4-alkylindene, with the hydrocarbon resin having a polydispersity index (PDI) of 1 to less than 2.3. Further described is a production process for the hydrocarbon resin, wherein a monomer mixture which includes an aromatic component including indene and/or C1-4-alkylindene and a cyclic diolefin component including a cyclic diolefin compound is polymerized by heating to a polymerization temperature of at least 180° C. to give a product stream including hydrocarbon resin, and oligomers which include 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.

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.
