Title:
A hyperactive nano iron catalyst for absorbing hydrogen sulfide
Document Type and Number:
Japanese Patent JP6240322
Kind Code:
B2
Abstract:
The invention involves the formation of a stable iron (II) oxide and/or hydroxide. Preferably these oxides and/or hydroxides are present as nanoparticles in the 5-10 nanometer range. It has been discovered that such particles can be formed at lower cost and with fewer impurities by using ferrous carbonate (FeCO3) from siderite as compared to known processes from various iron salts such as sulfates and chlorides. The novel nanoparticles are particularly adapted to removing sulfur compounds such as H2S from liquid and/or gaseous streams, such as hydrocarbon streams.
