ADDITIVE FOR HYDRAULIC PROCESSING AND METHOD OF ITS PRODUCTION AND APPLICATION Russian patent published in 2015 - IPC B01D15/00 B01J21/18 C10B55/00 C10G49/10 

FIELD: process engineering.

SUBSTANCE: proposed invention relates to method of fabricating of additive for hydraulic processing. Said process comprises the steps that follow. Carbon-bearing stock is fed to primary grinding zone to obtain ground material with particle size smaller than that of carbon-bearing stock. Ground material is dried to get moisture content smaller than about 5 wt %. Said dry ground material is fed to distribution zone to separate the particles of required size from those of inadequate size. Particle of required size are heated to 300-1000°C. Heated particles are cooled to magnitude smaller that about 80°C to get the additive. Target additive comprises solid organic material with particle size of 0.1-2000 mcm, bulk density varies from 500 to about 2000 kg/m³, structural density of 1000 to about 2000 kg/m³ and moisture content of about 0-5 wt %. Besides, this invention relates to hydraulic processing process. At application of additive in compliance with this invention, hydraulic processing can be effected at high transformation degree.

EFFECT: higher efficiency.
