METHOD OF PRODUCING BINDING MATERIALS Russian patent published in 1997 - IPC

Abstract RU 2083635 C1

FIELD: petroleum processing. SUBSTANCE: invention relates to oil-based binding materials finding use in highway engineering, in production of anode mass, electrodes, coal briquets, refractory materials, etc. Method includes thermal cracking of straight-run oil residues, vacuum distillation of cracking residue to produce still residuum with softening temperature 45-46 C, which is either withdrawn as road bitumen or (a part of residuum or whole residuum) subjected to heating and subsequent thermal polycondensation to yield oil electrode coke. EFFECT: improved process flowsheet and more harmonious exploitation of oil raw material. 1 tbl
