SMOKELESS FUEL

To Colliery Owners, Power

Users, Municipalities, &c.

THE ETICOAL SYNDICATE is now pre-
pared to negotiate for the erection of
plants for the production of smokeless
fuel for domestic or industrial use, upon
the basis of guaranteed results.

Semi-coking coals, washery residues and
numerous coals not usable under coke
oven practice can be profitably carbonized.

Under the process there is an available
surplus of high power gases, while the
benzol yields from both gases and tar, are
unusually large.
