A new, more comprehensive electronegativity scale

The electronegativity of atoms is one of the most well-known parameters for explaining why chemical reactions occur. Now, Martin Rahm, assistant professor of physical chemistry at Chalmers University of Technology (Gothenburg, Sweden; www.chalmers.se), has redefined the concept with a new,…

A single process to handle hydraulic fracturing produced water and offgases

Two major concerns in hydraulic fracturing operations are finding efficient ways to handle the massive amount of produced wastewater, and dealing with offgases from the well. A new technology developed by Ship & Shore Environmental Inc. (Signal Hill, Calif.; www.shipandshore.com),…

Gas analysis made easier for high-dust areas

A collaboration between Servomex (Surrey, U.K.; www.servomex.com) and FLO2R (Hadsund, Denmark; www.flo2r.com) has resulted in one of the industry’s first laser-based gas-analysis system for use in high-dust environments. Tunable diode laser (TDL) technology provides a much more rapid response than…

Co-electrolysis makes ‘green’ syngas in a single step

Last month, Sunfire GmbH (Dresden, Germany; www.sunfire.de) reported the successful startup and test run (more than 500 h) of a high-temperature, co-electrolysis system at its Dresden site since November 2018. The technology, called Sunfire-Synlink, is based on solid-oxide cells and…

New catalysts enable CO2-neutral olefins production via methane reforming

Today, olefins are mainly made either by naphtha cracking or by the catalytic conversion of dimethyl ether (DME), which is in-situ made from synthesis-gas- (syngas) derived methanol (methanol-to-olefin processes). Both naphtha cracking and syngas production (from steam-methane reforming; SMR) require…

Plasma-based electrolysis makes ammonia at ambient conditions

Researchers from Case Western Reserve University (CWR; Cleveland, Ohio; www.case.edu) have shown that a hybrid electrolytic system using a gaseous plasma electrode can produce ammonia from water and nitrogen at ambient temperature and pressure — without any catalytic material surface.…

CO2-to-chemicals effort boosted by electrocatalytic process

The quest to generate chemicals and fuels from exhaust or atmospheric carbon dioxide got a boost from a series of recent studies by researchers at Lawrence Berkeley National Laboratory (LBL; Berkeley, Calif.; www.lbl.gov), in which the scientists proved the viability…
