PROVISIONAL SPECIFICATION.
A New Fuel.
I ALBERT LEOPOLD KELLER of 88 Hatton Garden in the County of London,
Diamond Merchant do hereby declare the nature of this invention to be as
follows:-
I take absorbing materials (naturally combustible) such as peat either in its
natural state or compressed, or mixed with sawdust or coaldust etc. This material
I mould into bricks or leave it in its natural form. Then I thoroughly dry, either
by artificial or natural means in order to evaporate the water contained in it as
much as possible then I immerse it in a bath of hydro-carbons heated to a
temperature of 120 to 150 degrees Centigrade (a specially arranged tank is required
for the heating of hydro-carbons). The hydro-carbons I take in preference are the
refuses of petroleum or naphtha from which the benzine and kerosene oils have
allready been distilled or extracted, gas tar or the refuses of shale oils, parafine
These hydro-carbons can be combined at will with resins napthaline or
other cheap solid hydro-carbons.
etc. etc.
Under the influence of the aforesaid heating process the water still contained in
the peat or other material is evaporated or eliminated thereform, and at the same
time the pores of the material dilate which permit it to absorb a quantity of the
hydro-carbons which can amount to. 70 per cent. of the original weight of the wet
peat (the amount absorbed can be regulated both by the heat or by the duration of
the immersion). The material is then dried either naturally or artificially and can
then be used as fuel for steam engines or furnaces or domestic purposes or in fact
in almost every case where coal is generally used.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what I
claim is
The manufacture of a new fuel formed of naturally absorbing materials (already
combustible) which under the influence of heat absorb liquid hydro-carbons such as
petroleum naphtha gas-tar parafine and the refuse of shale oils etc. either of them
alone or together or mixed with solid hydro-carbons such as resins naptholine or
other cheap solid hydro carbons that will become liquid by heat mixed therewith.
In witness whereof the said Albert Leopold Keller have to this my
Specification set my hand this the Twenty second day of January One
thousand eight hundred and ninety one.

I ALBERT LEOPOLD KELLER of 88 Hatton Garden London Diamond
Merchant 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 statement :-
I take absorbing materials, naturally combustible, such as peat either in its
natural state or compressed, or else mixed with sawdust coaldust and etc. This
material 1 mould into bricks or leave it in its natural form. Then I thoroughly
dry either by artificial or natural process in order to evaporate the water contained
therein as much as possible. Then I immerse it in a bath of hydro-carbons heated
to a temperature of 120 to 150 degrees Centigrade. The hydro-carbons I take in

page_text: preference are the refuses of petroleum or naptha from which the benzine and
kerosene oils have been distilled or extracted gas-tar or the refuses of shail oils
parafine etc. etc. These hydro-carbons can be combined at will with resins napthaline
or other cheap solid hydro-carbons.
Under the influence of the aforesaid heating process, the water still contained in
the peat, or other material is evaporated or climinated therefrom and at the same
time the pores of the material dilate which permit it to absorb a quantity of the
hydro-carbons which can amount to as much as 70 per cent. of the original weight
of wet peat. The amount absorbed can be regulated both by the heat and also by
the duration of the immersion. The material is then dried either naturally or
artificially and can then be used as fuel for steam engines, or furnaces or for
domestic purposes, or in fact in almost every case where coal is generally used.
Having now particularly described and ascertained the nature of my inven-
tion and in what manner the same is to be performed I declare that what I
claim is
'
1st. The manufacture of a new fuel formed of naturally absorbing materials
already combustible which under the influence of heat absorb liquid hydro-carbons
such as petroleum naptha gas-tar parafine and the refuses of shail oils and etc.,
either of them alone or mixed together with solid hydro-carbons such as resins,
napthaline, or other cheap solid hydro-carbons that will become liquid by heat.
Dated this Twentieth day of October 1891.
