Ethylene oxychlorination catalyst

Background

Ethylene oxychlorination is the key technology in vinyl chloride (VCM, the monomer of PVC, polyvinyl chloride) production to close the chlorine loop by consuming the HCl released from the former cracking step. Due to the high demand for PVC, leading ethylene oxychlorination being one of the most important processes in the industry.

Chemical Properties

Light green microspherical solid, slightly irritating, can absorb moisture and agglomerate when exposed to air.

Uses

The catalytic oxychlorination of ethylene is widely used for the production of ethylene dichloride (EDC) which is an essential step for the production of poly-vinyl chloride (PVC). However, catalyst entrainment from the fluidization reactor has formed a problem and caused the loss of expensive catalyst powder with the outlet gas, hence less conversion in achieved.

Application

Ethylene oxychlorination catalyst is mainly used in the production of vinyl chloride (VCM) and pvc resin.
