METHOD OF OBTAINING METAL NANOPARTICLES Russian patent published in 2013 - IPC B82B3/00 C22B3/00 C22B5/00 C10G11/00 C10G47/00 

FIELD: nanotechnology.

SUBSTANCE: invention relates to the improved method of obtaining the metal nanoparticles for use in thermocatalytic processes of hydrocarbon crude refining. The method of obtaining the metal nanoparticles includes their recovery from organic metal salt in the thermal treatment conditions in a hydrocarbon crude medium, and the recovery is carried out of the organic salt having the formula M(OOC-R)_n or M(SOC-R)_n, wherein R represents alkyl, aryl, C₁₇H₃₃-, isoalkyl, tert-alkyl, alkylaryl, diethylamino-, possibly comprising a hydroxyl or amino group, n=1-3, and M represents a metal of the elements of the periodic table, at a temperature above the decomposition temperature of the said organic salt. The size of the nanoparticles obtained is preferably 1-100 nm.

EFFECT: improvement of the method of obtaining.
