SCAVENGING HYDROGEN SULFIDE FROM HYDROCARBON LIQUIDS Abstract This invention relates to scavenging hydrogen sulfide from hydro- carbon liquids. For this purpose, the hydrogen sulfide in the liquid is contacted with iron oxide particles typically containing a crystalline phase of Fe3O4 or Fe2O3 and combinations thereof together with an amor- phous Fe2O3 portion, and having a surface area of at least 3.5m2/g. Where for example, substantially anhydrous kerosene contains hydrogen sulfide in an amount in excess of 20 ppm, such hydrogen sulfide content is reduced to less than 10 ppm, thereby rendering it safe and salable.
