Oil shale and semicoke
can be combusted in boiler to produce electric power and heat [8-9].
Our earlier study of the origin of these phenols showed that most of them still originate from the process water added to the waste residue and even from the groundwater that had been contaminated with phenols before it was used for cooling the semicoke
When used for oil extraction, approximately half of the oil shale turns into semicoke
On continuous pyrolysis these mesophases are extensively deformed by bubble percolation; eventually viscosity significantly increases to allow further deformation and a fine fibrous microstructure of needle coke is established as the mesophase congeals to semicoke
All these changes were due to semicoke
formation, because in the range of about 350-500 [degrees]C the thermal degradation of coal proceeds, and gas (mainly hydrogen, methane and carbon oxides), reaction water and tar are evolved.
is also lagging behind in developing technologies for using coal in the future including processing coal into synthetic liquids, motor fuels, gas and semicoke

332 Mt of coke and semicoke

The study of hydration and carbonation reactions and corresponding changes in the physical properties of co-deposited oil shale ash and semicoke
wastes in a small-scale field experiment.
ESI FT-ICR MS and gas chromatography-mass spectrometry (GC-MS) disclosed that the major organic nitrogen components extracted from oil shale semicoke
The curve-resolved peaks that correspond to amino nitrogen disappear from the spectrum of the semicoke
of HD oil shale sample at 500 [degrees]C and from the spectra of semi-cokes of MM and YJ oil shale samples at 600 [degrees]C.
18% (stage II), while the semicoke
yield decreased from 80.
