METHOD OF REMOVING CS FROM HYDROCARBON STREAMS Russian patent published in 2024 - IPC C10G25/00 C10G25/05 C10G55/04 

FIELD: chemistry.

SUBSTANCE: invention relates to a method of producing a hydrocarbon stream with reduced content of CS₂, comprising contacting a hydrocarbon stream containing CS₂ with a solid reactive absorber CS₂, which contains hydrocarbon residues, bearing primary and/or secondary amino groups attached to a solid support, at a temperature in range from 0 to 300 °C, wherein the aliphatic hydrocarbon residues are bonded to the solid support through an alkoxysilyl group; and separating the obtained reaction product CS₂ and the reactive absorber CS₂ from the hydrocarbon stream. Invention also relates to the use of a solid absorber CS₂.

EFFECT: improved selective removal of CS₂ from liquid hydrocarbon streams.
