PROCESS FOR PRETREATMENT OF AN ISOMERIZATION PROCESS FEEDSTOCK CONTAINING LIGHT HYDROCARBONS

摘要

"PROCESS FOR PRETREATMENT OF AN ISOMERIZATIONPROCESS FEEDSTOCK CONTAINING LIGHT HYDROCARBONS"ABSTRACTA pretreatment process for removal of contaminantsfrom a light hydrocarbon isomerization feedstock ispresented. The feedstock is passed to a first adsorptioncontaining a molecular sieve and thereafter passed to asecond adsorption zone containing activated alumina. Theprocess produces a hydrocarbon feedstock substantially freeof sulfur compounds, oxygenates, and water. Such a processfinds utility as a feed pretreatment step preceding acatalytic isomerization process which uses a catalyst systemthat is sensitive to very small amounts of thesecontaminants.
