Process for synthesizing nickel carbonyl under normal pressure

Abstract

The invention discloses a nickel tetracarbonyl synthesizing method through nickel and CO under normal pressure, which comprises the following steps: grinding nickel material; sintering the grinded material; reducing sulfur content; leaching the sintered slag to separate the copper in the sintered slag; reducing the slag through water gas; synthesizing the product through reduced material and CO.

Description

technical field [0001] A method for synthesizing nickel carbonyl under normal pressure relates to a method for synthesizing nickel carbonyl by carbonylation of nickel-containing material and CO under normal pressure. Background technique [0002] Carbonylation metallurgy technology has been developed for more than 100 years in foreign countries. At present, three technologies of normal pressure, medium pressure and high pressure have been formed. The Canadian INCO company and the Russian North Nickel Company have the strongest strength in the application of carbonyl method to produce nickel abroad. The two companies used this technology to treat nickel resources such as nickel sulfide, nickel oxide, sponge nickel, and laterite ore, and achieved good results. China also has a history of more than 50 years in the research of carbonylation metallurgy technology, but it has not been systematic and industrialized, and the raw material is selected from electrolytic nickel, which h...

Problems solved by technology

Because it is produced under high pressure conditions, it has the disadvantages of high energy consumption, difficult control, difficulty in large-scale equipment, and easy to cause safety hazards.
