Conclusions
Microwave heating of the coal is advantageous for the
subsequent desulphurization. Conventional procedure of
coal desulphurization requires heating period about 40 minutes
and microwave procedures reduces this heating period
s533
for a few minutes. The use of microwave radiation for the
desulphurisation of coal displays potential and may be soon a
commercial reality. This would allow the use of high sulphur
coals in an environmentally and economically sound way.
