Synthesis and properties of bitumen from the residues of ‘charcoal oil’

Abstract

For the first time, the liquid road bitumen is obtained from the residues formed after hydrogenation of charcoal of ‘Karazhyra’ mine field. According to the values of physical–mechanical indicators, obtained bitumen corresponds to the bitumen of mark MG70/130. Chemical composition of obtained bitumen: 64% mass, paraffin–naphthene hydrocarbons; 13·48% mass, asphaltenes; 21·75% mass, resins. The viscous road oil bitumen is obtained by oxidation of liquid road bitumen, corresponding to bitumen of mark BND130/200 in terms of physical–mechanical indicators.
