Comparative characterization of semicoking oils obtained from rubber wastes and from co-processing of kukersite oil shale and rubber wastes in solid heat-carrier unit
V. Vysotskaya et al., Comparative characterization of semicoking oils obtained from rubber wastes and from co-processing of kukersite oil shale and rubber wastes in solid heat-carrier unit, OIL SHALE, 16(4), 1999, pp. 343-349
Semicoking oil was obtained from tires only and from kukersite with additio
n of tires in solid heat-carrier unit SHC-3000 at Estonian Power Plant in N
arva. Chemical composition of these oils has been studied using thin-layer
and gas-liquid chromatography. The semicoking oil obtained from tires only
contains 84.8% of hydrocarbons, 17.4% of which are nonaromatic compounds. T
reating kukersite together with tires improves oil quality, makes it lower
boiling and more unsaturated, increases the content of nonaromatic compound
s in oil up to 29.8%, and so brings its composition closer to that of comme
rcial liquid fuel.
