Improvements in Treating Peat, Coal, and other Carbonaceous
Substances for the Obtainment of Illuminating Gas.
I, JAMES MEIKLE, of 342, Gairbraid Street, Maryhill, in the County of
Glasgow, North Britain, Technical Chemist, do hereby declare the nature of this
invention to be as follows, that is to say :-
This invention has for its object the economical and advantageous obtainment
of illuminating gas from peat, coal, and other carbonaceous substances, and is
especially useful in treating carbonaceous substances such as by processes heretofore
in use have yielded gas of little or no illuminating quality, although it is also
applicable for improving the illuminating quality of various gases derived from
carbonaceous substances.
In carrying out the invention the peat or other carbonaceous substance is gasified
in any suitable kind of retort, and the invention consists in injecting, by means
of a jet or jets of superheated steam, into the gas whilst it is being formed or
immediately after it is formed, a spray of hydrocarbon or other suitable
carbonaceous oil, the oil thus injected combining with the gas and forming a gas
or gaseous mixture having an illuminating quality depending on the proportion of
oil injected. The oil spray may be injected into the retorts in which the gas is
formed or into a pipe, passage, space, or vessel through which the gas passes on
leaving the retort.
Deted this Hirst day of June 1896.

Improvements in Treating Peat, Coal, and other Carbonaceous
Substances for the Obtainment of Illuminating Gas.
I, JAMES MEIKLE, of 342, Gairbraid Street, Maryhill, in the County of
Glasgow, North Britain, Technical 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 statement, that is to say :-
My said invention has for its object the economical and advantageous obtainment
of illuminating gas from peat, coal, and other carbonaceous substances, and is
especially useful in treating carbonaceous substances such as by processes heretofore
in use have yielded gas of little or no illuminating quality, although it is also
applicable for improving the illuminating quality of various gases derived from
carbonaceous substances.
In carrying out my invention the peat or other carbonaceous substance is gasified
in any suitable kind of retort, and my invention consists in injecting, by means
of a jet or jets of superheated steam, into the gas whilst it is being formed or

page_text: immediately after it is formed, a spray of hydrocarbon or other suitable
carbonaceous oil, the oil thus injected combining with the gas and forming a gas
or gaseous mixture having an illuminating quality depending on the proportion and
quality of the oil injected.
Good results are obtained by using steam of about 40 pounds, pressure,
superheated to 700 degrees, Fahrenheit, and the oil employed may be an oil of
from 850 to 1.030 specific gravity; I do not however limit myself to these
quantities.
The oil spray may be injected into the retorts in which the gas is formed, or into
a pipe, passage, space, or vessel through which the gas passes on leaving the
retort; it is however necessary to maintain in such pipe, passage, space, or vessel
a heat approximately the same as that in the retorts.
Having thus particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
The treating of peat, coal, and other carbonaceous substances to obtain
illuminating gas, by injecting into gas being formed or immediately after being
formed from such substances, a spray of hydrocarbon or carbonaceous oil, by means
of superheated steam, substantially as hereinbefore described.
Dated this Twenty-seventh day of February 1897.
