National Energy Technology Laboratory (NETL) researchers developed a new catalyst that can selectively convert syngas into light hydrocarbon compounds called olefins for application in a $200 billion per year chemical industry market. The work has been detailed in ChemCatChem, a premier catalysis journal. The catalyst was characterized using a variety of techniques from U.S. Department of Energy user facilities at Brookhaven National Laboratory including advanced electron microscopy at the Center for Functional Nanomaterials and synchrotron-based X-ray spectroscopy conducted at the National Synchrotron Light Source II. An olefin is a compound made up of hydrogen and carbon that contains one or more pairs of carbon atoms linked by a double bond. Because of their high reactivity and low cost, olefins are widely used as building blocks in the manufacture of plastics and the preparation of certain types of synthetic rubber, chemical fibers, and other commercially valuable products.
