METHOD OF PRODUCING PROPPANT, PROPPANT AND METHOD OF APPLICATION THEREOF Russian patent published in 2024 - IPC C09K8/80 B01J2/28 C04B35/18 E21B43/267 

FIELD: oil, gas and coke-chemical industry.

SUBSTANCE: invention relates to the oil and gas industry, namely to the ceramic proppant manufacturing technology. Proposed method comprises preliminary thermal treatment of initial stock, its grinding, granulation in mixer-granulator with introduction of binder. At the final stage of granulation, initial heat-treated ground raw material is added. Then the obtained dried granules are fired at temperature of 900–1600 °C. Binder used is a suspension of particles with size of not more than 5 mcm of spent aluminium-cobalt-molybdenum gas cleaning catalyst in 8.0–12.0 % aqueous dextrin solution. Also disclosed are proppant and its application.

EFFECT: group of inventions allows increasing proppant strength.
