METHOD OF PRODUCING NICKEL CARBONYL

FIELD: process engineering. ^ SUBSTANCE: invention relates to production of nickel carbonyl by medium-pressure synthesis by means of metalloorganic compound synthesis reactor, slightly inclined and rotating. Initial loose material is fed into reaction chamber. Reactor housing is arranged at preset inclination and rotated about its lengthwise axis. Reactor inner space is flushed by nitrogen. Carbon oxide is forced into reactor to 50-70 atm. Circulation compressor is cut in to force carbon oxide through reactor. Heat carrier is fed into heat exchanger arranged inside reaction chamber to heat initial loose material to preset temperature. Synthesis is carried out at carbon oxide pressure of 50-70 atm while loose material is mixed in presence of carbon oxide. Mixing is performed by mixer integrated with heat exchanger. Along with mixing, loose material is transferred from one end of reaction chamber to another one to circulate loose material in closed loop into reactor inner space. After heating initial loose material to preset temperature coolant is fed into heat exchanger instead of heat carrier. Further, reaction chamber temperature is maintained equal to 170-220C. In case temperature is this chamber decreases heat carrier is again fed into reaction chamber. In synthesis, reaction product is discharged from said chamber along with filtration of dust and retaining loose material that did not react in reaction chamber. After synthesis, reaction chamber pressure is decreased to atmospheric pressure, filtration elements are blown by nitrogen and solid residues of loose materials are decontaminated in reaction chamber, now, loose material solid residues are withdrawn from reaction chamber. ^ EFFECT: higher efficiency of nickel carbonyl synthesis. ^ 10 cl, 8 dwg Изобретение относится к способу получения карбонила никеля. Способ реализуется при синтезе карбонила никеля среднего давления с помощью вращающегося с малым наклоном реактора синтеза металлоорганических соединений. В реакционную камеру реактора загружают исходный сыпучий материал. Корпус реактора устанавливают с заданным наклоном и приводят во вращение относительно его продольной оси.
