专利说明:
This invention relates to a process for the release of a perverse binder from a upp by treating a disintegrated upp at elevated temperature and pressure using aromatic; taken from TPs and mineral oils, solvents, and can be used in the geological and coking industry. A known method for producing a carbon-organic binder by mixing 1 part by weight of powdered cpp with 1 part by weight. and a larger masp followed by stirring and heating at 30–30 ° C for 30–24 ° min. The obtained pitch for desalting is treated with a polar organic solvent or an aromatic solvent l |. There is also known a method for producing a perodic binder from a gopp and residual masp by attaching finely ground powdered carbohydrate with petroleum residues, and then dissolving the mixture at 4OO-45 ° C, according to which 30pa contained in the coal coagulates together with insoluble microspheres contained in the crude oil the rest. The latter is specially pretreated and thus removed from the mixture 21. The closest to the invention is a method for preparing a permeable binder by mixing carbon with an aromatic solvent to form a suspension and treating it at elevated temperature and pressure. The disadvantages of the method are the necessity to use the stages of separation of the insoluble solids from the extract and the presence in the separated extract of an increased amount of ash ash, which affects the quality of the binder. The purpose of the invention is to obtain a high quality, permeable binder in the production of electrodes. The goal is achieved by combining a binder with an aromatic solvent with the formation of a slurry binder and processing it at II (with a high temperature, as carbon and joining, it mixes with dissolving the mixture, and mixes with a dissolvable matte, which is mixed with a mixture of matrices and mixes with an aromatized solvent, which is mixed with solvent and matrices. , boiled coal, with a SOJcr-Horo temperature of boil-off of 416-4651 and a cracking residue “Yeukin with a temperature of 50% boil-off of 350-435С, with the following ratio of components in suspension, wt.%: Desiccated coal 5-4 O Aromatic m Spa with a temperature of 5O% boiling out 416-4b5s 20-80 residue, cracking of oil fractions with a temperature of 5O% boiling out of 350-435 ° C 15-50 and processing the suspension is carried out at ZOO-42Os, pressure 5-50 bar within 1-4 hours with the removal of low-boiling fractions and, if necessary, followed by mixing the resulting mixture with 30-60% by weight of pitch with a softening temperature of 115-160 °, obtained from carbonic or mineral oils. According to the proposed method, coal is used and in the disintegration circuits of the latter, residues from the splitting of naphtha or gas oil in the vapor phase, the residue and from catkracking, delayed coking, as well as high-boiling aromatic diethyls obtained as a result of raffiating of coal-tar nesa, with a mean boiling point above 350 ° C. In addition, up to 60% is used to finalize the flow of coking residue, taking into account the product obtained by disintegrating ugg, for example, residues from the distillation of coal tar pitch or, preferably, from distillation of pyrolgas oil with a softening point of 115-160 0 (Cremer’s and Sarnova), and the variety of CCP is only of secondary importance. However, preference is given to carbon seals with a high carbon content, and this in its own way. nature must be such that it is possible to separate it in a known way. In order to ensure the wide applicability of the proposed method, a desalting method is chosen, according to which the ash content of the coal is reduced by intensive chemical treatment with acids and bases. Other methods of sanitizing are also suitable, and when using ultrapure coals with ash content below 1.%, the separation of ash can be avoided. De-coaling coal & 1 will prescribe chemical reactions under severe conditions with the use of KEYPOT, bases and will oxidize them, affecting the dissolution of carbon, particularly in the case of oxidizing treatment of coal, pre-decay of pac-t in aromatic compounds. When used for disinfection, UGF solvents should be as low as possible. This requirement is satisfied in particular by pyrolysis oils obtained by splitting mineral oil fractions in the vapor phase, distillates obtained by refining coal tar, and residual oils obtained by delayed coking and selected coal tarry. For dry ash, cracking residues can also be used as additional solvents. ; It is preferable to use pyrolysis oils obtained as a result of the splitting of mineral oil fractions in the vapor phase, since these oils have a pronounced tendency to poly. merization, which is beneficial for obtaining large residues from coking. Among the coal tar oils, preference is given to distillates obtained by treating the coal tar pitch with heat and pressure with a midpoint of a higher boiling point or similar distillates obtained from the processing of coal tar by distillation.
