A NEW OR IMPROVED PROCESS FOR THE MANUFACTURE OF A MINERALIZED CARBON FOR FILTERING, DISINFECTING & OTHER PURPOSES
Year: 1884

page_text: I JAMES WRIGHT GATEHOUSE of the city of Bath, Analytical Chemist do hereby
declare the nature of the said invention for "A NEW OR IMPROVED PROCESS FOR
THE MANUFACTURE OF A MINERALIZED CARBON FOR FILTERING, DISINFECTING &
OTHER PURPOSES to be as follows:-
This invention relates to a new or improved process for making a silico-carbon
suitable. for use as a deodorizer, filtrant, and disinfectant as well as for other
purposes to which charcoal is usually applied.
Whereas by the distillation of crude lignite or by its. treatment with processes
such as that described in my Provisional Specification N° 1557 dated the twenty
seventh day of March 1883, the result has been the production of a very friable
compound which from its loose state of aggregation and physical qualities was
unsuitable for the rapid filtration and deodorization of liquids required to be treated
in large bulk.
The present invention has for object to remedy such defects and to produce
from lignite a carbonaceous material in which the decolorizing, disinfecting and
deodorizing properties of lignite carbon is intensified and whereby rapidity of
filtration is secured at the same time and the invention consists in the carbonization
of lignite in conjunction with siliceous minerals either obtained naturally or by.
calcination in a sufficiently porous state to produce a carbonaceous material suitable
for the above named purposes.
.
In carrying out my invention I take mineral matter containing large amounts
of silica either free or in combination with bases, such as felspar, diatomaceous
earths, grit stones, sand stones, volcanic tufa or pumice, greenstone, ganister, dinas
rock, manganese silicates, fuller's earth, ochre, umber, or silicious clays such as pipe
clay or fire clay which either naturally or after calcination is sufficiently porous to
absorb gaseous hydro-carbons or any mixture of the above and intimately blend
the same with. lignite (which. by preference has been previously dried and
granulated) in such proportions that the resulting carbonaceous product obtained
by distilling the mixture in suitable retorts shall.contain from 20 to 60 per cent of
mineral matter and from 80 to 40 per cent of carbon according to the special
purposes to which it is to be applied.
The carbonaceous mixtures thus obtained possesses decolorizing, disinfecting and
deodorizing properties in the highest degree.

This invention relates to a new or improved process for making-a silico-carbon

the resulting carbonaceous-product-obtained-by-distilling the mixture in suitable

The carbonaceous mixture thus obtained possesses decolorizing, disinfecting and

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 mineralized carbon by the carbonization of lignite in
conjunction with silicious minerals either obtained naturally or by calcination, in
the manner, hereinbefore described and the use of such mineralized carbon for
filtering and disinfecting purposes.as hereinbefore described.
