Description

technical field [0001] The invention belongs to the technical field of nickel refining, and in particular relates to a nickel carbonyl synthesis device and a synthesis method thereof. Background technique [0002] At present, most of the nickel carbonyl synthesis process uses thin nickel waste such as water-quenched nickel or nickel skin as raw materials, which are put into vertical carbonylation reactors in batches according to the requirements of technical conditions for carbonylation reaction to produce nickel carbonyl, and carbonyl The chemical synthesis kettle works intermittently, about 30% of each cycle needs to be shut down for other preparations, and 70% of the time is for oxo synthesis reaction, and the use efficiency is low. In the context of the global nickel sulfide resources decreasing day by day, the raw materials for the above-mentioned nickel carbonyl synthesis are gradually in short supply, resulting in the failure of the nickel carbonyl synthesis to procee...
