    Abstract: 1,174,278. Acetylene. BADISCHE ANILIN- & SODA-FABRIK A.G. 21 April, 1967 [22 April, 1966], No. 18429/67. Heading C5E. Acetylene is produced by incomplete combustion of gaseous or vaporized hydrocarbons (e.g. light naphtha) with oxygen, with subsequent quenching, the reaction being carried out in the presence of CO 2 which is added continuously to the hydrocarbon feed, the oxygen or the mixture thereof prior to the reaction in an amount of 10-50 vol. per cent with reference to the oxygen amount. Carbon black formation is reduced and acetylene yield increased.

    Abstract: 1,194,738. Separating acetylene. BADISCHE ANILIN- & SODA-FABRIK A.G. 10 Nov., 1967, No. 51277/67. Heading C5E. In the separation of acetylene from gas mixtures, obtained by thermal or electrical cracking of hydrocarbons with or without oxygen, by means of selective absorption by a recycled solvent followed by fractional desorption, non- volatile polymers formed in the solvent are separated from the solvent, e.g. by distillation, the separated polymers are treated with water, and the resultant aqueous solution after separation from insoluble residue is combined with the recycled solvent. The process is stated to prevent deposition of polymers within the system. In the example the solvent is N-methylpyrrolidone.

    Abstract: 950,345. Oxidizing carbonaceous material in gaseous suspension. BADISCHE ANILIN- & SODA-FABRIK A.G. Oct. 31, 1961 [Nov. 4, 1960], No. 38864/61. Heading B1X. [Also in Division F4] Carbonaceous material in suspension in an oxidant-resistant liquid is oxidized in a chamber wherein the liquid is evaporated by the combustion of auxiliary fuel and the material is mixed with an oxygen-containing gas stream by an orifice plate. A slurry of carbon black in water is delivered to a combustion chamber 1 through an atomizer 8. Air and fuel are supplied tangentially at 9, 10 to burn in a chamber 7 surrounding the atomizer 8 and entrain the slurry in a whirling stream of hot gases. Additional air or oxygen introduced at 15, 16 cools the chamber walls and the carbon black burns in a ring of flame above an orifice plate 11 which causes the intimate mixing of the gases so that combustion is completed in a chamber 3. The chamber 3 discharges tangentially to a cylindrical separator 4 and the gases are fed to a heat exchanger 13 to preheat air or fuel, and used to concentrate the aqueous slurry in a vessel 5. A condenser 6 allows the liquid to be recovered.

    IPC: C07C7/171

    Abstract: Acetylene obtained from hydrocarbons, e.g. by partial combustion or electric arc cracking is purified by contact with 85-90% sulphuric acid at 30-40 DEG C. to remove other unsaturated and organic or inorganic sulphur compounds. The purification is preferably effected by countercurrent contact, e.g. in a tower packed with Raschig rings.
