Abstract
A process for removal of trace impurities of hydrides of arsenic, phosphorus, antimony, silicon, and boron and sulfur and oxygenates and compounds containing these impurities from a hydrocarbon stream comprising contacting the hydrocarbon stream with an adsorbent material selected from the group consisting of zeolites and promoted alumina to adsorb compounds containing sulfur and/or oxygenates, contacting the hydrocarbon stream with an adsorbent material comprising one or more active metal oxides to remove the hydrides and contacting the hydrocarbon stream with an adsorbent material that removes water.
