REGENERABLE SORBENTS FOR REMOVAL OF SULFUR FROM HYDROCARBONS AND PROCESSES FOR THEIR PREPARATION AND USE

摘要

A sorbent for use in removing sulfur contaminants from hydrocarbon feedstocks is provided, wherein the sorbent contains zinc aluminate in an amount of at least 40 wt% (calculated as ZnAl₂O₄); free alumina in an amount of from about 5 wt% to about 25wt% (calculated as Al₂O₃); and iron oxide in an amount of from about 10 wt% to about 30 wt% (calculated as Fe₂O₃); wherein each of the free alumina and iron oxide are present in non-crystalline form as determined by X-ray diffraction analysis, and a method for producing the sorbent and method for using the sorbent to reduce sulfur contaminants in hydrocarbon feedstocks.
