Description

The patent description was published: March 15, 1982 112895 Int. Cl. * C09C 1/52 Creators of the invention: Zenon Jurkiewicz, Leszek Zurzycki, Jerzy Kropiwnicki, Kazimierz Forys, Jan Maslon, Henryk Mazur¬ kiewicz, Erwin Sroka. Authorized by the patent: Gliwice Zaklady Chemical "Carbochem", Gliwice (Pol & ^ a) Process for the production of pigment carbon black. The object of the invention is the production process. The use of pigment carbon black with a deep black surface and a high specific surface, which is sandwiched for the production of printing inks, and as a pigment for paint, varnish, plastic and fiberglass.

A large part of the current demand for laaidzy PPR is hidden by the production of this product by the canal or furnace method. In these processes, raw materials are subjected to incomplete combustion in a closed space of pinooelsoi. The reactions are most often carried out at an oversize of air and the presence of hydrocarbons of various origins, most often oils with a high content of aromatics, soot is often obtained in the form of a suspension from which the product is collected on the ehloidophilic surface and by the exhaust gases further comprising water vapor, nitrogen, carbon dioxide, carbon dioxide, Ia, methane and acetylene.

One of the important factors that determine the properties of carbon black is pawfieprachinfia i tóiwia.

In pre-industrial manufacturing processes, the aim is to obtain a product with particles that are as similar as possible. For this reason, in the technological regime of carbon black production, the technological parameters, such as the dosing amounts of the fuel gas and air fuel, needed to obtain a given type of carbon black, are determined.

The quality of the product in the process of carbon black production is influenced by a number of factors: raw material kiimethics, the method of injecting the raw material into the re-refractory, the time of exposure to the injection factors in and refractory, and the type of product produced and the speed of cooling the soot formed.

As the present quantity, this is called s / melting spalatmiia, is defined by s (ie isitisunek illoscii wprofWajdizomegio potwdetmzla), to dlpsciii said poitrzeibnegid for complete combustion, 'Injected into hydrocarbons irraacton. The stated ratio determines the size of the soot particles in the display. Due to the fact that airborne oils are more efficiently used as a carbon black raw material, the quality of the product is influenced by the preparation of the reaction mixture of the laiminiain or the turbulent slothirelph of the reaction. After the end of the process, the gas mixture is heated, the carbon black cools and cools and pirizes with water, or by depositing on cooled surfaces. The product's properties are influenced by (also to a large extent and multiplied by slippery stones).

The prc-product properties are determined analytically, for example by measuring the feorption of the diphtheria or oil or iodine.

The essence of the game was to dioiboly of the real eadiotechnical raw material, and the ratio of azowegio, to the optimal ratio of the gaseous medium to the oil, to the selection of the phylum of this alcoholic combustion of the idiolsitjoso-tertiafi, to the elepithebitalia. The intestine can lead to the production of the pigment fibrous in the prizemiscus scale.

According to the formula, pigment black is produced by a method of producing and coking gas from the mixture of parlolegru ~ airiitaaicenowy iziaw & erajaicego 50—0 # Vo parts of the weight of aromatic carbohydrates with an intrinsic energy, and tricyclic and coking gas. The optimal isittolsuine by weight of the hydrocarbons of the coco-carbonate for the production of a pigmeinite carbon black having a surface area of the order of 10 to 0.20 m2 / g is equal to 2 µm.

The process grinded the fracture of the steam (paQJaindia mliieisizairuiina steam evidencing the force in apiculture burners, the ratio of the length of the slot to its width is determined by the value of 30-Hlo: l. PailnrM are situated at an angle of 30-45 ° and the jsitpis.

Burning is judgmental in the presence of a regulated amount! diabloed air at a temperature of 1270-1473 ° K under a reduced inzed contamination of 0.5-2.0 mm HjO. The product jsptsylamjia in the cavity collects the sediment on the surface of the drum and the carbon blacks together with the gaseous products of the carbon dioxide combustion process, the catfish is separated on the filters. Firing of drum balances; it is a product with a curl size in the order of 32M56 mm and a proper surface, 10-15-1-120 m2 / g. The soot fraction of the filters is smaller, in the order of 29-44 nm, and specific surface area, in the order of 90-105 m2 / g.

Each fraction can be used separately or in a thin air, optionally after concentrating it to a granular coating of 50-50 g / l as a pigment. Depending on the intended use of the carbon black, the drum carbon black is mixed with the carbon black obtained from the carbon black in a 1: 1-H2 weighted silt and thickens the mixture to a bulk density of 150-250 g / L As in the process * according to the invention, the anthracene oil used is evaporated by heating the diaphragms, weep it in a descaling agent and collect the vapors in a continuous way, mixing them in a watered ratio with the coke oven gas. The mixture is introduced into slotted burners with narrow slots of the order fl, 25h-0.4P mm and the length of which is 12 mm. The distance between the individual burners and the settling powder was 45 to 85 mm, the burners in the isftosumide to the axis of the drum being positioned at 30 ° to 45 °.

Produced in the procejsite as a result of a non-total sptailand, it is seated on the drum and is considered by scrapers and transported to the trash. The carbon blacks, carried by the flue gas stream formed in the process of micro-coal combustion, separate the soils on bag filters.

By means of a method according to the invention, by selecting the appropriate weight ratio of the carbon black fraction with the drum and the filter fraction, it is possible to adjust the product assortment depending on the current needs of the recipient, without changing the technological parameters of carbon black production. For example, the carbon black intended for printing f, atribs is replaced by • by thickening and with the help of ignliolterów to oieZJar (bulk 200 g / 1 isia fraction | between odeibirtaniej ..;.; ......% fJiiLtrólw ..
