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…

Accelerated electrons unlock sugars from cellulosic biomass

Obtaining sugars from cellulosic biomass cost-effectively is difficult because the predominant biopolymers in plant material evolved to protect these sugars. A process currently being scaled up for obtaining sugars from waste agricultural biomass employs beams of accelerated electrons to fracture…

Selective oxidation of methane makes formaldehyde, without generating CO2

Researchers from South Korea have discovered a high-performance catalyst for the selective oxidation of methane to formaldehyde. The study was conducted by staff from Ulsan National Institute of Science and Technology (Ulsan; www.unist.ac.kr), Ajou University (Suwon; www.ajou.ac.kr) and Hanyang University…

Mechanical CO2 sequestration improves algae production

A new, mechanical method for sequestration of carbon dioxide into water was evaluated at the University of Texas’ (Austin; www.utexas.edu) Bioproducts and Bioenergy Analytical Service Center and has revealed a pathway to economically improve algae growth for production of oils.…

Process intensification for carbon capture could reduce costs

In conventional solvent-based carbon-capture systems, CO2-rich exhaust gas contacts gravity-driven solvents in a vertical packed-bed column. A novel approach developed by Carbon Clean Solutions USA Inc. (CCSUS; Cumming, Ga.; www.carboncleansolutions.com) employs centrifugal force from rotating horizontal packed beds to effect…

New membranes resist biofouling using sunlight

Membranes in large-scale water-treatment processes are often fouled by accumulation of bacteria or their biofilms. Now, a team of researchers from Washington University St. Louis (WUSTL; St. Louis, Mo.; www.wustl.edu) have combined graphene oxide and bacterial nanocellulose to design a…

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…
