    (5) METHOD FOR PRODUCING A HIGH-AROMATIC PEK006-STANDARD PRODUCT FROM COAL
    This invention relates to methods for producing a highly aromatic, pectoral product from coal and can be used in the refining and coal chemical industries. A method is known for producing a pewer product by heating powdered coal with pitch to form a homogeneous mixture of CO. A method is known for producing a peeled product by stirring and heating the pulverized coal with a highly aromatic oil residue, followed by separating the solvent from the undissolved solids zj. Closest to the invention is a method for producing a high-aromatic pezokoobrazny product from coal by mixing ground coal with a solvent at 350-50 ° C and elevated pressure to form a fluid and pumpable suspension. A mixture of petroleum heavy oil is used as a solvent: a type of boiler fuel, anthracene and creosote oils with an acidic coal fraction, Q consisting mainly of f3J phenols. However, the resulting highly aromatic peck-shaped product does not have a smooth fracture and high gloss, is not homogeneous and has a syrup consistency. The purpose of the invention is to obtain a peck-shaped product with a smooth fracture and high gloss. The goal is achieved by the fact that according to the method of obtaining a highly aromatic pitch-like product from coal by mixing crushed coal with a solvent, a mixture consisting of petroleum oil with a boiling point of S0% 350-600 ° C, which is a residue of the pyrolysis process, is used as a solvent. vapor phase fractions, 3,95963 coal aromatic oils with a boiling point temperature of 50–350–600 0 and, if necessary, waste products of the cracking process in the form of aromatic resin oils with a temperature of j Swarm of boiling 50 250-350 0, with the following ratio of components in suspension, weight D: Aromatic petroleum oil Process waste 5-10 cracking and the resulting suspension is grmogenized ts at 250-20 C, 0, MPa for 1-5 hours. PRI me R 1.

Starting materials for the preparation of a highly aromatic ne co-shaped product from coal: 30% COAL (Westerholt) 10% coal gas pitch; 5% pitch distillate; 35% gas oil pyrolysis residue and 20% pitch distillate; gas oil pyrolysis residue (boiling point, 50% before), 12% of the residue of catalytic cracking process vacuum distillation (start of boiling, 50% before), and 11% gasoline pyrolysis pitch (Kish) intensively mix, get well flowing at a temperature above the pumped suspension, which is heated at a speed of one hour to obtain the desired temperature for processing and with good agitation in a vibrating autoclave, is kept for 3 hours. After cooling, relieve pressure from the pressure tank and separate gases and water. The molten product is discharged from the autoclave. The effect of pressure and temperature on the properties of the obtained product is shown in Table. 1. .Ta blitz 1 1.6 121 10.8 35.9 1.5 39.9 1.50 109 I, 8 k, 2 1.6 46.2 1.48 102 27, 7.8 1.7 53.9 pressure (boiling point, 50% to 416 s) is subjected to homogenization followed by treatment as in example 1..

However, the reaction product at room temperature is not peculiar, but syrupy and partially crystalline. Example 8. 30 parts by weight coal (Westerholt) is treated for 3 hours with EO weight.h. oils from gasoline pyrolysis (boiling point 200 ° C, 50 to 80, 80). 65% of the coal is converted to a quinoline soluble form. However, the reaction product is n homogeneous. After a short time, the precipitation of small grains in the form of bottom sediment can be observed. Example 9. 33% gas coal (Vesterholt) is subjected to interaction with 3 acid fractions from rectification of coal tar and 33% of mineral oil residue from thermal reforming at, for 1 hour, the maximum pressure is 62 bar C. However, the reaction product is extremely inhomogeneous and syrupy consistency. Very good homogenization of refined carbon products cannot be achieved even in the case of low boiling parts separation. Thus, examples 7-9 show the advantage of the proposed method compared with the known
