Abstract
Prior to subjecting a butene-1 containing stream isomerization to produce butene-2 in the presence of a catalyst, e.g., a palladium catalyst, the feedstream is subjected to pretreatment in the presence of a contact mass adapted to remove under pretreatment conditions from the feedstream impurities which adversely affect the catalyst, e.g., sulfur and arsenic.
