have never been driven home to the
public at large as they have been
brought to universal attention by the
world wiae coal shortage during the
war.
hough the Berlin patent office mas
not yet rendered decision OF Prueck-
ner's application Tor patent on his
synthetic coal process the fact that
PrueclNner produced synthetic coal
that in every respect is the equal OF
anthracite has been established be-
end any doubt by a number of official
practical tests.
one OF the tests was made to ascer-
tam the heating power OF each OF the
two kinds OF fuel The synthetic coal
burned without a smell and with an
insignificant volume of smoke and
produced 1895 heat units per 100 kilo-
grams. 22O pounds while anthracite
coal has a heating power OF from 1000
to 5000 heat units per 100 kilograms
and emits many times more smoke.

means that synthetic coal. if used to
produce directly heat or steam, at
least equals high grade anthracite.
Gas and Coke.

verted into gas and coke.
rne gas obtained from the synthetic
COL yielded more heat units per sec
ond while it lasted and it lasted longer
than the anthracite. The coke OF both
kinds OF coal eQualed in weight and
heating power. The result is OF special
importance because Germany is con-
sistenty striving to restrict consump-
ton OF coal to factories and gas works,
and has already made much progress
in that direction.
The heat from burning coal is to be
utilized to make steam to drive sta
tiOnary engines. But thereby not more
than is per cent OF the inherent power
of coal can be utilized. Not to waste
the remaining power. the fires be-
meath the boilers will be connected
with gas generating plants, the illu-
gas yielding about twice as
much heat or power as the direct
burning of coal
The chief product of that process is
coke to be burned on board of ships
and in households, which may also use
either illuminating gas or hydrogen
gas for heating purposes. The hy-
irogen gas is produced by pouring
water on live Goals. Small and me-
iium industrial establishments will by
md by have to INSTALL gas motors and
Use illuminating or hydrogen gas. DR..
Walter Rathenau, former president of
he Allgemeine Elektricitaets-G esell-
ichaft General Electric company, es-
imated that by these improvements
coal consumption can be reduced so
DER cent.
The Process.
The process of production of syn
hetic coal is simple, according to
2rueckner who operates near Munich
/ small plant. Prueckner said:
Factories will be erected in the vi
Unity of quarries. Two different kinds
IF soft stones are crushed and ground
nto fine sand and mixed with certain
chemicals. The mixture will be mois-
ened, pressed into briquettes, heated.
Tried and cooled
The synthetic coal industry will not
lepend on anthracite or bituminous or
-btuminous coal or peat or on
heir by-products, or on any other ma
erial used as fuel.
Germany like nearly every other
Ountry. has a superabundance of the
necessary minerals and can produce
he chemicals in unlimited quantities.
AS produced in the little plant near
1unich, synthetic coal can be sold to
he consumer at half the price of an
hracite. 1t is certain that the cost of
he product will be reduced when the
manufacture on a large scale is be-
I'M"
The formula is of course kept secret
t the present time, and probably will
OF be disclosed when a patent is
ranted. For of all the victors of the
ord war, only three-England. Bel
ium and Italy-have renOunced up to
ow their Versailles treaty privilege to
inject the property rights and in
rests of German nationals to excep-
onal war measures that have been
will be taken with regard to them"
in other words, to seize German
including patents.
For that reason there is no prospect
lat synthetic coal will be produced
Inside of Germany until non-Ger-
an makes an invention similar or
entical with that of Prueckner, the
unich druggist.
