摘要：
Processes comprising: providing a catalyst comprising a catalytic component selected from the group consisting of ruthenium, ruthenium compounds, and combinations thereof, wherein the catalyst is sulfur-poisoned with one or more sulfur compounds; and treating the catalyst with a gas stream comprising a hydrogen halide under nonoxidative conditions such that the catalyst is regenerated.
