PROVISIONAL SPECIFICATION.
Improvements in the Process of Making Gas and a Product
arising therefrom.
I, WILLIAM DYSON of Goldthorpe, Oldcotes, in the County of Nottingham,
Farmer, do hereby declare the nature of my invention to be as follows:-
In carrying out my invention, I propose to cause the gas from the retort to pass
through enclosed masses of peat moss, instead of water as at present, so that the
crude gas in forcing a passage through the peat moss, parts with the ammonia
which is in it, the separation or extraction being effected in a more perfect and
complete manner than by water.
The gas is not only better purified, but the peat moss in combination with the
extracted ammonia forms a high class tillage or manure, and becomes a valuable
product.

COMPLETE SPECIFICATION.
Improvements in the Process of Making Gas and a Product
arising therefrom.
1, WILLIAM DYSON of Goldthorpe, Oldcoates, in the County of Nottingham,
Farmer, 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 :-
This invention relates to improvements in the manufacture of coal gas, such as
is used for lighting and other purposes, and in the production of a composition or
material during such gas manufacture which forms a valuable tillage.
In carrying out my invention, I cause the crude or unpurified gas, during the
process of manufacture, to pass through purifying tanks or chambers filled with
peat-moss, in place of the usual water tanks.
The gas while forcing its way through the fibres of the moss, parts with the
ammonia that is being carried along with it, and the process of extraction or
separation of the ammonia is effected in a more complete and perfect manner than
by water.
The peat-moss having performed its duty and become charged with ammonia
separated from the gas in its passage through it, is then treated with sulphuric acid
thereby fixing the ammonia. A high class tillage or manure being very valuable
product is then produced.
Thus my invention is in the first place a superior method of purifying gas during
the process of its manufacture, and secondly producing by such method of purifi-
cation a valuable product, namely a tillage.
Having now particularly described and ascertained the nature of my inven-
tion, and in what manner is or may be performed, I declare that what I
claim is :-
1-In the manufacture of coal gas, causing the crude gas to pass through an
enclosed mass of peat-moss, instead of through water, to more effectually separate
the ammonia therefrom, substantially as herein before described.

page_text: 2-The production of a material for tillage purposes, consisting of peat-moss
charged with ammonia by passing the crude gas during the manufacture of
carburetted hydrogen gas, (or ordinary coal gas,) through an enclosed mass of
peat-moss and fixed by a treatment of sulphuric acid, substantially as hereinbefore
described.
Dated the 3rd day of December 1891.
