Research ArticleOpen accessIn the author namesStudy of Supercritical Coal Extraction in Toluene Containing FluidsPeter Nikolayevich Kuznetsov, Svetlana Mikhaylovna Kolesnikova, Ludmila Ivanovna Kuznetsova, Anastasia Valerievna KazbanovaThe conversion of brown coals and sapropelic coal in toluene containing mixtures with co-solvents (water, ethanol and tetralin) was studied under sub- and supercritical conditions within the temperature range of 375-550°C and at pressures from 7 to 40 MPa. It was found that the extent of coal extraction in the toluene solvent medium, at 400°C, was significantly increased by the … …American Journal of Applied Sciences, Vol. 13, Issue 3 · 1 Mar 2016 · 7,610 accessesView PDF Cite

Research ArticleOpen accessIn the author namesGetting an Alternative Pitch Binder by Thermal Dissolution of CoalPeter Nikolayevich Kuznetsov, Elena Nikolaevna Marakushina, Anastasia Valerievna Kazbanova et al.The process of thermal dissolution of medium metamorphosed coals in anthracene oil to produce an alternative pitch binder was studied. The process was carried out at temperatures from 350 to 400°C and pressure not higher than 2.5 MPa, without the use of hydrogen and catalysts. It was determined that during thermal dissolution hard coal of gaseous-fat grade demonstrated a higher … …American Journal of Applied Sciences, Vol. 13, Issue 1 · 4 Jan 2016 · 8,138 accessesView PDF Cite
