A more direct chemical route to ketones
Using a simple, ligand-free palladium catalyst system, researchers at McGill University (Montreal, Que., Canada; www.mcgill.ca) have demonstrated that metal carbonylation — a core chemical reaction for many industrial products — can be used to synthesize ketones directly from hydrocarbons. The…
A push for ‘green’ steel
Last month, the so-called Hybrit initiative (www.hybritdevelopment.com) was given the go-ahead to build a pilot plant for making fossil-free steel. The announcement follows a pre-feasibility study conducted by Swedish partners SSAB AB (Stockholm; www.ssab.com), LKAB (Luleå; www.lkab.com) and Vattenfall AB…
‘One-pot’ synthesis of conjugated polyenes
The research group of professor Masafumi Hirando at Tokyo University of Agriculture and Technology (TUAT; Koganei City, Japan; www.tuat.ac.jp) has performed the world’s first one-pot synthesis of conjugated polyenes, which normally require at least seven steps by conventional methods. This…
Chementator Briefs
Glycolic acid Researchers from the group of professor Miho Yamauchi at the International Institute for Carbon-Neutral Energy Research (I2CNER) of Kyushu University (Fukuoka City, Ito Campus, i2cner.kyushu-u.ac.jp) have fabricated a liquid flow-type electrolyzer that can continuously produce an alcohol from…
Progress towards aluminum-ion batteries
Compared to conventional lithium-ion batteries, aluminum-ion batteries (AIBs) offer significant advantages, such as non-flammability, and a high capacity of the metallic Al anode. However, due to inadequate cathodic performance, especially capacity, high-rate capability and cycle life, AlBs cannot compete with…
Biomass fractionation and conversion technology to be scaled up
Plans are underway for a demonstration-scale facility in France that will convert non-food lignocellulosic biomass into raw materials for bio-based chemicals and animal feed products, such as feed for fish farming. The process, developed by Arbiom (Research Triangle Park, N.C.;…
New process converts refinery offgas into gasoline
A process technology that upgrades offgas from petroleum refineries has been commercialized by Siluria Technologies Inc. (San Francisco, Calif.; www.siluria.com) and Wood (Aberdeen, Scotland; www.woodplc.com). According to Siluria, the new Modus technology’s ability to chemically convert refinery offgases into high-quality…
Direct conversion of methane into methanol and acetic acid
In a recent paper, published in Nature, the Flytzani-Stephanopoulos group from Tufts University (Medford, Mass.; www.tufts.edu) identified a new method for the direct conversion of methane into methanol or acetic acid under mild conditions using oxygen, carbon monoxide and a…
Recycled polymers improve the nylon product chain
Although recycled polymers can provide sustainable, low-cost feedstock, their use is challenging in applications that require high-performance characteristics. Vertellus LLC (now Aurorium) has developed additives to improve processors’ ability to incorporate recycled nylons and recycled polyesters into virgin nylon. One…
Lower-cost sulfur-removal process for syngas goes commercial
An adsorbent-based, sulfur-removal process for synthesis gas (syngas) that lowers capital and operating costs compared to alternative methods of removing sulfur has completed pre-commercial testing and has achieved commercial status. The Warm-gas Desulfurization Process (WDP; diagram) has been under development…
