Description
<Desc/Clms Page number 1>
L'objet de la présente invention est un procédé de fabrica- tion de divers produits de forte résistance mécanique, plus spé- cialement d'un combustible solide formé à partir de matériaux solides à grains fins et non-cokéfiants, par exemple de coke.
Le procédé selon la présente invention consiste en ce que le matériel non-cokéfiant à grains fins est aggloméré en pro- duits de forme quelconque, par exemple en briquettes, en y uti- lisant comme liant des produits de dégazement de charbon de terre, de lignite ou de bois, ou bien des produits obtenus à
<Desc/Clms Page number 2>
partir de pétrole brut, les produits ainsi façonnés étant ensui- te soumis à un traitement thermique dans des conditions détermi- nées de température et de temps, celles-ci dépendant de la matiè-. re première dont on a fait usage, avec utilisation de l'oxydation augmentant la résistance mécanique du produit obtenu et rendant la structure de celui-ci plus dense.
Dans les procédés précédants de production de coke, formé par briquetage, le charbon ou les briquettes sont également traités dans des températures élevées avec des gaz contenant de l'oxygène, mais ce traitement thermique avec de l'oxygène n'est effectué que pour détruire le pouvoir cokéfiant, celle-ci don- nant lieu à une déformation des briquettes et à leur agglutina- tion lors des procédés technologiques ultérieurs ou bien afin d'obtenir un combustible sans fumée par la destruction de rende- ment du goudron.
Conformément à l'invention, ledit traitement thermique avec utilisation de.l'oxygène est utilisé afin d'obtenir un accrois- sement de la résistance mécanique du produit obtenu.
Des examens et des expérimentations ont démontré que ledit accroissement de la résistance mécanique des briquettes produi- tes, par exemple des briquettes de coke, se manifestant lors de leur traitement thermique avec utilisation de l'oxydation, est dû aux conversions chimiques ayant lieu, sous l'influence de l'oxygène et de la température, dans le liant utilisé, dans le sens de la polymérisation et de la condensation des composés contenus dans le liant.
En formant des briquettes ou d'autres produits formés on peut faire usage d'une addition de substances inorganiques, par exemple de minérai de fer ou autres, de fluorines et de pareils ingrédients.
Le procédé selon l'invention se prête par exemple non seulement à la fabrication de coke ou de semi-coke pour des buts
<Desc/Clms Page number 3>
métallurgiques et énergétiques, mais également à la fabrication de divers produits organiques et inorganiques formés.
Il est à mentionner qu'en cas de nécessité d'obtention d'un plus haut degré de dégazement des produits formés, confor- mément au procédé selon l'invention ceux-ci sont soumis de nou- veau à un traitement thermique dans une température de 500- 1000 C.
Exemple. ,
100 tonnes,de semi-coke contenant 7-8% de matières volati- les, ayant une granulation de 3 mm, ou bien 100 tonnes d'un mélange de composition quelconque :demi-coke, coke, anthracite, substances inorganiques, sont mêlées avec 10 tonnes de liante température de ramollissement 50 C obtenu à partir du goudron 'primaire par distillation des fractions jusqu'à 200 C. Le bras- sage est effectué dans un malaxeur ordinaire en chauffant à l'aide de vapeur.
Après un brassage vigoureux de la masse, elle est soumise au briquetage dans des presses oviformes, tout en maintenant la température de la masse à une hauteur de 60-70 C.
Les briquettes déjà faites sont soumises à l'oxydation dans des dispositifs quelconques, par exemple sur une bande mobile sans fin, dans des dispositifs à cuve etc., en y utilisant comme moyen de chauffage les gaz de la combustion contenant de l'air à l'excès.
L'oxydation se fait dans une température de 240 C. La durée de l'oxydation dépend de la grandeur des briquettes et elle s'élève à quatre heures quand les dimensions des briquettes sont de 60 x 60 x 40 mm.
Après le refroidissement en plein air les briquettes oxy- dées constituent un produit tout fait.
Leur résistance mécanique selon la méthode de Micum est de 90-95 /M40/.

The object of the present invention is a process for the manufacture of various products of high mechanical strength, more especially of a solid fuel formed from fine-grained and non-coking solid materials, for example coke.
The process according to the present invention consists in that the fine-grained non-coking material is agglomerated into products of any shape, for example briquettes, using therein as a binder products of degassing of charcoal, of carbon. lignite or wood, or products obtained from
<Desc / Clms Page number 2>
starting from crude oil, the products thus shaped being then subjected to a heat treatment under determined conditions of temperature and time, these depending on the material. re first which has been used, with the use of oxidation increasing the mechanical strength of the product obtained and making the structure of the latter more dense.
In the previous processes of producing coke, formed by briquetting, coal or briquettes are also treated at high temperatures with gases containing oxygen, but this heat treatment with oxygen is carried out only to destroy coking power, which gives rise to deformation of the briquettes and their agglutination during subsequent technological processes or else in order to obtain a smoke-free fuel by destroying the yield of the tar.
According to the invention, said heat treatment with the use of oxygen is used in order to obtain an increase in the mechanical resistance of the product obtained.
Examinations and experiments have shown that said increase in the mechanical strength of the briquettes produced, for example coke briquettes, manifested during their heat treatment with the use of oxidation, is due to the chemical conversions which take place under the influence of oxygen and temperature, in the binder used, in the direction of polymerization and condensation of the compounds contained in the binder.
In forming briquettes or other formed products, use can be made of an addition of inorganic substances, for example iron ore or the like, fluorines and the like.
The process according to the invention lends itself, for example, not only to the manufacture of coke or semi-coke for purposes
<Desc / Clms Page number 3>
metallurgical and energy products, but also in the manufacture of various organic and inorganic products formed.
It should be mentioned that if it is necessary to obtain a higher degree of degassing of the products formed, according to the process according to the invention, these are again subjected to a heat treatment at a temperature. from 500- 1000 C.
Example. ,
100 tonnes of semi-coke containing 7-8% volatile matter, having a granulation of 3 mm, or 100 tonnes of a mixture of any composition: semi-coke, coke, anthracite, inorganic substances, are mixed with 10 tons of 50 ° C. softening temperature binder obtained from the primary tar by distillation of the fractions up to 200 C. The brazing is carried out in an ordinary kneader while heating with steam.
After vigorous stirring of the mass, it is subjected to briquetting in oviform presses, while maintaining the temperature of the mass at a height of 60-70 C.
The briquettes already made are subjected to oxidation in any devices, for example on an endless moving belt, in vat devices etc., using therein as heating means the combustion gases containing air to excess.
The oxidation takes place at a temperature of 240 C. The duration of the oxidation depends on the size of the briquettes and it amounts to four hours when the dimensions of the briquettes are 60 x 60 x 40 mm.
After cooling in the open, the oxidized briquettes are a ready-made product.
Their mechanical resistance according to the Micum method is 90-95 / M40 /.
