Carbonyl sulfide is the chemical compound with the linear formula OCS. Normally written as COS as a chemical formula that does not imply its structure, it is a colourless flammable gas with an unpleasant odor. It is a linear molecule consisting of a carbonyl group double bonded to a sulfur atom. Carbonyl sulfide can be considered to be intermediate between carbon dioxide and carbon disulfide, both of which are valence isoelectronic with it.

The invention provides a multicore palladium cluster compound for catalytically hydrolyzing carbon disulfide and carbonyl sulfide. The multicore palladium cluster compound is an azacyclo- di-core palladium (II) cluster compound and has the general formula of ([(N^N)2Pd2(NO3)2](NO3)2), wherein (N^N) represents a ligand and is one selected from pyridine, dipyridine, alkylpyridine, pyrroline and phenanthroline. The invention further provides a preparation method for the multicore palladium cluster compound and an application of the multicore palladium cluster compound. The multicore organic-metal cluster compound provided by the invention serves as a catalyst for removing sulfur from the carbon disulfide and the carbonyl sulfide through hydrolysis and is used for catalytically hydrolyzing the carbon disulfide and the carbonyl sulfide in a low-temperature (room-temperature) aqueous solution in a high-efficiency manner so as to produce a carbon dioxide and sulfidion (S<2->) bridged intermediate product of a tri-core palladium cluster compound, and finally, the recycling of the catalyst is achieved through an oxidation-reduction reaction between concentrated nitric acid and the tri-core palladium cluster compound.

ActiveCN109420410AImprove removal abilityHigh acid gas loadGas treatmentDispersed particle separationSodium IsethionateCarbonyl sulfide

An absorbent for efficiently removing organic sulfur in an acidic gas mixture is provided and suitable for efficiently removing organic sulfur such as carbonyl sulfide and mercaptan in an acidic gas stream, belonging to the field of gas purification. The absorbent is characterized in that the absorbent comprises N-methyldiethanolamine, monoethanolamine, N,N-dimethylformamide, water and an additivethat is sodium isethionate. The absorbent includes 30-50% (wt) of the N-methyldiethanolamine, 10-15% (wt) of the monoethanolamine, 5-10% (wt) of N,N-dimethylformamide, and 0-5% (wt) of the additive that is sodium isethionate, with the balance being water. This absorbent has good performance and large acid gas load.
