DECOMPOSITION OF ORGANIC CHLORIDE IN ALKYLATE USING METALS AND ALLOYS

摘要

Processes for decomposing organic chloride in a hydrocarbon stream may comprise contacting a hydrocarbon stream with a dechlorination element in a dechlorination zone under dechlorination conditions to provide a dechlorinated hydrocarbon product, wherein the dechlorination element may comprise a metal or metal alloy having a high surface area configuration. Such a dechlorination element may be disposed within one or more distillation columns and/or within a separate dechlorination vessel.

主权项

1. A dechlorination process, comprising:
a) providing a hydrocarbon stream comprising an alkylate product in combination with an organic chloride contaminant; and b) contacting the hydrocarbon stream under dechlorination conditions in a dechlorination zone with a dechlorination element having a surface area per unit volume in the range from 250 to 1000 m2·m−3 to decompose the organic chloride and to provide a dechlorinated alkylate product, wherein the dechlorination element has a metal surface comprising a metal alloy.
