Abstract
A pretreatment process for removal of contaminants from a light hydrocarbon feedstock is presented. The feedstock is passed to a first adsorption zone containing a molecular sieve and thereafter passed to a second adsorption zone containing activated alumina. The process produces a hydrocarbon feedstock substantially free of sulfur compounds, oxygenates, and water. Such a process finds utility as a feed pretreatment step preceding a catalytic isomerization process.
