Patent GB-861381-A (GB)
Title: A method for the preparation of granules of condensed phosphate perhydrates
IPC: C01B15/16
Filed: 1958-07-03
Abstract: Condensed phosphates in pulverulent, nonvoluminous form are sprayed with aqueous hydrogen peroxide whilst in continuous movement in a mixing apparatus, the rate of addition and concentration of hydrogen peroxide being such as to produce a relatively voluminous, granular product.  0.5 to 2.5 mols. of H2O2 are preferably added per mol. of phosphate. Phosphates mentioned are sodium pyrophosphates, tripolyphosphates and polyphates having an average composition corresponding to hexa- and hepta-polyphosphates; mixtures containing polyphosphates are preferred due to the stabilizing effect.  The heat of reaction may be removed by means of a stream of cooled air or of water cooled equipment, and may, if desired, be used subsequently for dehydration, alternatively the heat of reaction may be used to effect dehydration before or immediately after reaction.  Suitable apparatus include vertical or horizontal mixers with slowlymoving stirring or mixing devices, rotating drums or air mixers operating by the turbulent motion induced by injected air.  After formation the granules may be classified, e.g. by sieving.  Stabilizers other than polyphosphates may be used, e.g. magnesium sulphate, metasilicate or polysilicate, alkali metal salts of aminopolycarboxylic acids, protein products, protein hydrolysates and fatty acid or sulphonic acid protein condensation products: these may be added to the condensed phosphates or to the hydrogen peroxide or may be formed in situ, for example by adding magnesium sulphate to the phosphate and water glass to the peroxide.  The products may also be stabilized with compounds reducing the pH value; acid phosphates may be included for this purpose in the phosphate starting material, or sodium bisulphate, oxalic acid or amido-sulphonic acid; acid salts or acids, e.g. ortho-, pyro- or polyphosphoric acids may be added to the hydrogen peroxide. Carboxymethyl cellulose may be added as a strengthener.  Porous products of improved solubility may be obtained by mixing an alkali metal carbonate or bicarbonate with the phosphate and an equivalent quantity of acid, preferably ortho-, pyro- or polyphosphoric acid, with the hydrogen peroxide, whereby carbon dioxide is liberated in situ.  The granules may be further stabilized during or after size classification or dehydration by coating with a lyophilic compound, e.g. paraffin oil, lyophilic oils, fatty acid amides, fatty acid ethanol amide, fatty acid polyglycol ester, alkyl polyglycol ether or alkyl phosphates. Specification 767,636 is referred to.

Title: Process for the recovery of hydrocarbons from a sludge
IPC: C10G31/08
Filed: 1947-08-06
Abstract: A sludge formed by treatment of hydrocarbons with an acid-acting polymerization catalyst such as aluminium chloride, hydrogen fluoride or sulphuric acid is hydrolysed with an aqueous hydrolysing medium in the presence of a low-boiling inert hydrocarbon liquid, the hydrolysis temperature being maintained at the boiling point of said liquid which is refluxed so as to dissipate the heat of hydrolysis as the heat of vaporization, hydrocarbons suitable as drying oils being recovered from the product.  The hydrolysing medium may be water or aqueous acids, alkalis or salts.  The hydrocarbon liquid may be butane or pentane, for low temperature hydrolysis, octane or gasoline or naphtha fractions boiling below 200 DEG  C.  The boiling point may be further varied by adjusting the pressure.  Hydrolysis in the absence of air or oxygen gives improved products.  After hydrolysing, the product is stratified, and the hydrocarbon layer neutralized and distilled to separate the hydrocarbon and recover the oil.
