Abstract: A method of removing reactive metal from a metal-coated reactor system, comprising contacting at least a portion of a metal-coated reactor system containing reactive metal with a getter to produce movable metal, and fixating the movable metal, the getter, or both. The contacting is preferably done prior to catalyst loading. A preferred coating metal comprises tin and a preferred getter comprises HCl. The invention is also a method for reducing catalyst contamination from a metal which was used to coat a reactor system. The method comprises contacting a metal-coated reactor system, with a gaseous halogen-containing compound to produce movable metal; thereafter or simultaneously, at least a portion of the movable metal is removed from the reactor system. Then a halided catalyst is loaded into the reactor system.
