A sulfur-tolerant catalyst for the deoxygenation of sulfoxides

The transformation of sulfur-containing molecules is an important reaction in organic and pharmaceutical chemistry. However, the sulfur atom strongly coordinates with the active sites of metal catalysts, significantly decreasing the catalytic performance. Sulfur impurities contained in chemical feedstocks also cause…

Quantum-inspired computing technology drastically accelerates materials design

Semiconductor materials contain numerous ingredients in various mixing ratios, and high-performance materials are obtained by optimizing the formulation. However, more than 1,050 theoretical combinations of ingredients and mixing ratios need to be analyzed, so it would take more than dozens…

Advanced amine-scrubbing solvent offers carbon-capture advantages

Honeywell UOP (Des Plaines, Ill.; www.honeywell.com/uop) recently began offering a post-combustion carbon-capture system based on new advanced solvent technology that allows for improved carbon-capture economics for hard-to-abate industries, such as steelmaking, rotary kiln operations (such as cement-making) and natural-gas power…

Demonstration plant will convert waste biomass into emissions-free hydrogen

A new demonstration plant near Bakersfield, Calif. will produce carbon-negative “green” H2 from woody biomass waste, such as agricultural residues from orchard trees and walnut shells. Developed by Mote, Inc. (Los Angeles, Calif.; www.motehydrogen.com), with engineering partners Fluor Corp. (Irving,…

This new thermoplastic elastomer has a large impact resistance

Thermoplastic elastomers (TPEs) are typically copolymers of a plastic and a rubber that have both thermoplastic and elastomeric properties. The best-known TPEs include styrenic block polymers, which contain molecular blocks of polystyrene (which is hard) and polydiene (which is rubbery).…

Renewable dimethyl ether plant planned

Engineering design is underway for a new plant for making renewable dimethyl ether (rDME) from biogas produced by agricultural digesters or derived from landfills. Project developer Oberon Fuels (San Diego, Calif.; www.oberonfuels.com) is basing the new plant on its existing…

Chementator Briefs

Drive & Charge The R&D teams from Holcim Ltd. (Zug, Switzerland; www.holcim.com) and Magment GmbH (Oberhaching, Germany; www.magment.co) have developed a unique concrete with high magnetic permeability, which enables electric vehicles to recharge wirelessly while in motion. Known as inductive…

Reducing the carbon footprint of quicklime production

Decomposing limestone (CaCO3) into quicklime (burnt limestone; CaO) releases significant CO2 emissions, both from the combustion of fuel needed to heat the kiln to temperatures over 1,000°C, and by the release of CO2 from the reaction itself (CaCO3 → CaO…

Large-scale production of insect proteins from waste

Agronutris (Saint Orens de Gameville, France; www.agronutris.com) has selected Bühler AG (Uzwil, Switzerland; www.buhlergroup.com) as its process-solution provider for its first commercial-scale black-soldier-fly plant. Bühler will deliver a full-scope solution for the facility, which will be built in Rethel, France.…
