Have in view of a) the presence of various systems of coke ovens, which in practice gives a different thermal regime; b) deviations from the average thermal conditions inherent in individual plants; c) the desire of coke plants to shorten the period of coking of the charge to increase the capacity of the furnaces, as a result of which the heat-up mode of the furnaces and, consequently, the conditions for the pyrolysis of hydrocarbons are made more stringent, seems reasonable:

1. To enhance the pyrolysis of the raw material introduced into the coke oven, introduce the latter through a tube passing through the hatch cover and reaching the upper layers of the coking charge. At the same time, the jet from the tube is distributed over the charge and the coke-type Hiemem HGV is pyrolyzed.

2. For this purpose, as well as to increase the amount of pyrolysis raw materials, load a coke oven with underload at one or another section of the furnace. The underload may be 12-15% of the total furnace load, -The pyrolysis feed bay should be produced at the site furnaces with underload. The speed of the feed can be significantly increased by

Pyrolysis enhancement score.

3. To see the conditions of pyrolysis, pour the pyrolyzable raw material into the furnace along with water. The amount of water must be coordinated with the optimal mode of the coke oven (or furnace battery). The most convenient form is by pouring the emulsion of the pyrolyzable raw material with water taken in the right amount.

An emulsion with water can be prepared in a separate tank to be pumped into the pressure tank supplying the entire battery of furnaces. Naphthenic acids in the form of sulfosalts as well as other emulsifiers are suitable for preparing the emulsion.

Some types of raw materials, such as peat tar, sometimes contain significant amounts of emulsified water; in this case, the further addition of water may be unnecessary and the raw material may be directly poured into the coke oven. The addition of WATER to the pyrolyzable raw material reduces the excess heat in the pyrolysis zone, protects the hydrocarbons from pyrolysis to coke TiT Kpowe, which, together with coal coal, will give an additional amount of gas

4. For the same purpose, for moderate heat dissipation in the pyrolysis zone, it is possible to introduce pyrolyzable feedstock along with some water vapor.

The subject matter of the invention.

The method of pyrolysis of yefty, resins and the like materials through the introduction of coal into the coke oven during the coking period, characterized in that the pyrolysis materials are introduced into the cracking zone in the form of an aqueous emulsion.
