PROVISIONAL SPECIFICATION.
A New or Improved Process for the Decolorization of Palm Oil.
We, JOHN LONGSDON GARLE, of No. 136, Holland Road, Kensington, and
COLIN CHARLWOOD FRYE, of No. 21, Woodville Road, Ealing, both in the county
of Middlesex, Students of Chemistry, do hereby declare the nature of this invention
to be as follows:-
This invention relates to a new or improved process for the decolorization of
palm oil.
In carrying the invention into effect, a quantity of palm oil or "palm butter," as
it is technically known in the trade, is placed in a suitable vessel and rendered
fluid by the aid of heat from a gas or other fire or steam, care being taken that
the degree of heat does not exceed about 100° C. aud when the material is
sufficiently fluid it is run off or decanted from the heating vessel into a filtering
apparatus maintained at the degree of heat necessary to preserve the fluidity of
the material.
The material, after it is sufficiently strained or filtered, is next run off into a
closed vessel provided with an outlet and heated by a gas or other fire or steam
and at its lower part fitted with a grating or diffuser or a perforated coil of pipe
or like contrivance which is connected with a suitable pump or injector by the aid
of which ozone, ozonised oxygen or ozonised air, which may contain a small
proportion of vapour of suitable oxides of nitrogen and such as nitric-peroxide
or nitric oxide, is forced through the body of the fluid material and this treatment
is continued until the required decolorization of the material has been effected,
the material during the operation being carefully kept at a temperature which
will retain it in a liquid state but which should not be higher that about 100° C.
Instead of forcing the ozone, ozonised oxygen, or 'ozonised air through the
body of fluid material it may be drawn therethrough by exhaustion, as will be
really understood.
By the means herein before described, the decolorization of palm oil may be
effected in a more rapid, economical and absolute manner than heretofore.

page_text: of Middlesex, Students of Chemistry, do hereby declare the nature of our invention
and in what manner the same is to be performed to be particularly described and
ascertained in and by the following statement:-
Our said invention relates to a new or improved process for the decolorization
of palm oil.
In carrying the invention into effect, a quantity of palm oil or "palm butter,"
as it is technically known in the traile, is placed in a suitable vessel and rendered
fluid by the aid of heat from a gas or other fire or steam, care being taken that
the degree of heat does not exceed about 100° C., whilst preferably it is only
sufficiently high to retain the oil in the melted state, and when the material is
sufficiently duid it is run off or decanted from the heating vesel into a filtering
apparatus maintained at the degree of heat necessary to preserve the fluidity of
the material.
The material, after it is sufficiently strained or filtered, is next run off into a
closed vessel provided with an outlet and heated by a gas or other fire or steam
and at its lower part fitted with a grating or diffuser or a perforated coil of pipe or
like contrivance which is connected with a suitable pump or injector by the aid
of which ozone, ozonised oxygen or ozonised air, preferably as pure as possible
but which may without any great disadvantage contain a small proportion of
vapour of suitable oxides of nitrogen and such as nitric peroxide or nitric oxide,
is forced through the body of fluid material and this treatment is continued until
the required decolorization of the material has been effected, the material during
the operation being carefully kept at a temperature which will retain it in a liquid
state but which should not be higher than about 100° C. whilst the most suitable
temperature for the purpose is that which is just sufficiently high to melt the oil and
retain it in a melted condition.
Instead of forcing the ozone, ozonised oxygen or ozonised air through the body
of fluid material, it may be drawn therethrough by exhaustion, as will be readily
understood.
By the means hereinbefore described, the decolorization of palm oil may be
effected in a more rapid, economical and absolute manner than heretofore.
Having now particularly described and ascertained the nature of our said in-
vention and in what manner the same is to be performed, we declare that what
we claim is:-
A process for the decolorization of palm oil, consisting in maintaining the oil
in a Huid state and passing ozone, ozonised oxygen or ozonised air therethrough,
substantially as herein described.
