Abstract
Methods for scavenging carbon disulfide ('CS') from hydrocarbon streams using treatment compositions comprising at least one CSscavenger and at least one phase transfer catalyst therein. The CSscavenger may comprise at least one polyamine with the general formula: HN—(R—NH)—R—(NH—R)—NHwherein R, R, Rmay be the same or different H, aryl or C-Calkyl; and x and y may be integers from 0 to 10. A hydrocarbon product with a reduced concentration of CStherein.
