Kp. Singh et Mc. Kakati, EFFECT OF ATOMIC O S RATIO, H/C RATIO AND NITROGEN-CONTENT IN COAL ONMICROWAVE DESULFURIZATION EFFICIENCIES AND MODELS FOR THEIR PREDICTIONS/, Research and Industry, 38(4), 1993, pp. 260-263
In microwave desulphurization atomic ratios of O/S, H/C and nitrogen c
ontent in coal are found to be very important coal parameters. The lin
ear relationship is found to exist between sulphatic sulphur removal e
fficiency and atomic O/S ratio. The pyritic sulphur removal efficiency
is found to correlate strongly with Wt% nitrogen content in coal. The
organic sulphur removal efficiency is correlated to atomic O/S ratio
with polynomial of degree three. Total sulphur removal efficiency is a
lso correlated with atomic O/S and H/C ratios with polynomial of degre
e three in each case. In all the developed correlations, correlation c
oefficient (r) values are found to be greater than 0.98.
