Abstract
A process for the production of vinyl chloride comprises the step of passing a feed stream comprising ethylene dichloride (EDC) over a catalyst system comprising a dehydrochlorination catalyst and a hydrochlorination catalyst at a temperature, which may be in the range 150-350° C., sufficient to effect dehydrochlorination of the ethylene dichloride to produce vinyl chloride.
Claims16
A process for the production of vinyl chloride, comprising:
- passing a feed stream comprising ethylene dichloride over a catalyst system comprising a dehydrochlorination catalyst and a hydrochlorination catalyst at a reaction temperature and reaction pressure sufficient to effect dehydrochlorination of the ethylene dichloride to produce vinyl chloride,
- wherein the feed stream contains essentially no hydrogen,
- wherein the dehydrochlorination catalyst comprises a supported noble metal catalyst that comprises at least one of platinum, palladium, ruthenium, and rhodium, and
- wherein the hydrochlorination catalyst comprises at least one metal selected from the group consisting of gold, mercury, palladium, silver, ruthenium, iridium, platinum, rhodium, copper, bismuth, tin, zirconium, antimony, lead, and compounds thereof.
