PROVISIONAL SPECIFICATION.
Improvements in the Manufacture of Illuminating Gas, Artificial
Fuel Blocks, and Coke for Metallurgical Purposes.
I, GASTON DE VELNA, of 26 Kue de Turin, Paris, France, Chemist do hereby
declare the nature of this invention to be as follows:-
For manufacturing illuminating gas special kinds of bituminous coal such as
cannel coal are used because they contain a certain quantity of hydrocarbons.
For obtaining more gas and of better quality, there are, according to my
invention, added to any kind of coal or other combustible matter hydrocarbons so
prepared that they shall be retained with the molecules of the distilled coal, thus
profiting by the maximum of their useful effect both in the production of more gas
and in the increase of the illuminating power.
The hydrocarbons employed, consisting mainly of tar from petroleum schistes &c.,
are for this purpose formed into a kind of emulsion, which is obtained by suitably
heating and mixing the following substances:
Oleine or any fatty acid
Soda-lye
Tar of petroleum or schiste
-
2 to 10 parts
0.1 to 1
-
89
to 98 "
دو
The coals to be distilled are intimately mixed with the emulsion in suitable
proportion, according to their quality generally the proportion varies from 5
to 15 per cent. of the emulsion to from 85 to 95 per cent. of coal.
The whole is introduced into retorts in the ordinary manner of manufacturing
gas and a gas is thus obtained which is better, gives a greater light, and yields.
richer and more abundant bye-products than ordinary gas. There is, in particular,
an increase in the production of tar and a notable improvement in the coke
produced.
The use of the emulsion with very poor coal dust or anthracite dust will give to
these, which as a rule only produce coke dust, the property of agglomerating during
the distilling process and of furnishing coke for metallurgical processes, which is so
sought after by various industries.
The emulsion can also be added to the various kinds of small fuel or carbonaceous
dust such as of anthracite, coal, lignite, peat, wood &c., for forming the same into
artificial fuel blocks, the heating power of which will thereby be greatly increased.

5 Improvements in the Manufacture of Illuminating Gas, Artificial
Fuel Blocks, and Coke for Metallurgical Purposes.
I, GASTON DE VELNA, of 26 Rue de Turin, Paris, France, Chemist, do hereby
declare the nature of this invention and in what manner the same is to be
performed to be particularly described and ascertained in and by the following
0 statement :-
For manufacturing illuminating gas special kinds of bituminous coal such as
cannel coal are used because they contain a certain quantity of hydrocarbons.

page_text: For obtaining more gas and of better quality, there are, according to my
invention, added to any kind of coal or other combustible matter hydrocarbons so
prepared that they shall be retained with the molecules of the distilled coal, thus
profiting by the maximum of their useful effect both in the production of more gas
and in the increase of the illuminating power.
The hydrocarbons employed, consisting mainly of tar from petroleum schistes &c.,
are for this purpose formed into a kind of emulsion, which is obtained by suitably
heating and mixing the following substances:
Oleine or any fatty acid
Soda-lye
Tar of petroleum or schiste
to 10 parts
0.1 to 1 "
89
to 98 "
A suitable emulsion may be obtained by mixing 440 parts by weight of tar of
petroleum or schiste with 50 parts of oleine, and 10 parts of soda lye. The whole
is heated to from 60° to 80° C.; as soon as the mass begins to rise it is withdrawn
from the fire and allowed to cool while stirring. To this mixture may be added
coke dust, and by adding a quantity of ordinary pitch, briquettes may be produced
either for making gas or for producing heat.
The coals to be distilled thus intimately mixed with the emulsion in suitable
proportion, according to their quality, are introduced into retorts in the ordinary
manner of manufacturing gas and a gas is thus obtained which is better, gives a
greater light, and yields richer and more abundant bye-products than ordinary gas.
There is, in particular, an increase in the production of tar. and a notable
improvement in the coke produced.
The use of the emulsion with very poor coal dust or anthracite dust (for example
in the proportion of from 4 to 5 per cent. of the said mixture) will give to these,
which as a rule only produce coke dust, the property of agglomerating during the
distilling process and of furnishing coke for metallurgical processes, which is so
sought after by various industries.
The emulsion can also be added to the various kinds of small fuel or carbonaceous
dust such as of anthracite, coal, lignite, peat, wood, &c. for forming the same into
artificial fuel blocks, the heating power of which will thereby be greatly increased.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
The above described process for the preparation of the emulsion and the appli-
cation thereof to the production of illuminating gas and coke for metallurgical
purposes, as also the use of the said emulsion for the manufacture of fuel blocks.
