Patent GB-847528-A (GB)
Title: Improvements relating to the treatment of clay
IPC: C01B33/40
Filed: 1957-06-21
Abstract: The replacement of exchangeable cations in a clay of the expanding lattice type, for example a bentonite or hectorite, is effected by first replacing the exchangeable cations by treatment with a cation exchange resin charged with intermediate cations, which are then eliminated as a gas by contacting the treated clay with a solution containing the final cations.  The final cations are usually those of an organic base, and are preferably derived from an amine of high molecular weight and boiling point, for example diethylene triamine, triethanolamine, pentamethylene hexamine, para-diisobutyl phenoxy ethoxy ethyl dimethyl benzyl ammonium chloride, or dimethyl octadecylamine; they are advantageously polymerizable, such as the reaction product of a polyamine and a polycarboxylic acid, for example diethylene triamine and phthalic anhydride; or they may be metallic cations, for example lead, larger than the original cations, such as may be derived from lead acrylate, in which case the product will contain some polymerizable material.  The final cations are preferably larger than the initial cations, which are normally sodium or calcium.  The intermediate cations are preferably ammonium ions, but may also be substituted ammonium ions derived from compounds of low molecular weight, for example methylamine and dimethylamine. This treatment reduces the swelling properties of the clay in water, and is suitable for use as a dielectric film, having improved dielectric properties.  The cation exchange resin may be a sulphonated phenol-formaldehyde resin or a sulphonated cross-linked polystyrene resin.  The intermediate cation may either be eliminated as a gas by ensuring that it is a weaker base than the final cation, or by carrying out the final replacement at above the temperature at which the cation is evolved as a gas from the clay.  Low molecular weight silicates, sulphates, and chlorides may be removed from the p initial clay suspension by treating with a strongly basic anion-exchange resin, either before or after the introduction of the intermediate cations, or by employing a mixed bed of the resins, simultaneously.  In one example, an aqueous hectorite suspension was treated with a cation exchange resin in the ammonium form, and was then spread out as a film on glass plates and dried.  This film was then treated with a solution of diethylene triamine and phthalic anhydride in water, dried, and the organic cation polymerized by heating.

A gas having a high CO content is made by gasification, under pressure, of a solid fuel with gasification media including CO 2 ; the CO 2  being derived by scrubbing the product gas of the gasification, whilst still under pressure, with a liquid which dissolves or binds CO 2 , the regeneration of the liquid being also effected under pressure whereby the liberated CO 2  needs compression only to the degree required. for re-admission to the gasification chamber. The gas-generator 1 is supplied with oxygen and water vapour through pipes 13, 14 and with CO 2  through the pipe 15. A pressure of 20-40 atmospheres is maintained. The gas passes through pipe 16 to a cooler 2 wherein it is sprinkled with water from a pipe 17 to remove water vapour, tar and dust, and from thence to a scrubbing tower 3 for removal of CO 2 , Solutions of potash or caustic soda, or, for the treatment of fuels of low tar and sulphur content, amines and amino-alcohols and similar organic bases or aqueous solutions thereof, are referred to as scrubbing agents. The cold lye leaving the scrubber 3 is heated in a heat-exchanger 4 and enters a regenerator 5 where it is further heated by a steam coil 18 which drives off most of the CO 2  which is returned to the generator via the booster. 7 and pipe 15. The hot regenerated lye is returned to the top of the scrubber 3. through the hot path of the exchanger 4 by a a pump 6. The product gas, rich in CO, is with drawn at the top of the scrubber 3, and if further removal of CO 2  is desired, a second stage of scrubbing, similar to the first, with scrubber 8, exchanger 9, regenerator 10 may be provided.
