The demand for vanillin vastly outstrips the natural resources of this flavoring agent. A chemical process is thus used to produce the required large quantities of vanillin from petroleum, which is far less expensive than obtaining the substance from fermented…
Pneumatic conveying is a versatile method for transporting powders and other solid materials within chemical process plants. Success depends on understanding science and applying specific experience Undergraduate engineering programs include little instruction about powder handling. While there may be some…
Chemists at Hokkaido University (Sapporo, Hokkaido, Japan; www.global.hokudai.ac.jp) and the Institute for Chemical Reaction Design and Discovery have developed what is said to be the first high-performance catalyst specifically designed and optimized for solid-state, mechanochemical synthesis. The new approach was…
Accurate water-monitoring technologies support short- and long-term sustainability goals in both municipalities and the industrial sector In recent years, São Paulo, Cape Town and other major world cities have come dangerously close to running out of water, and the criticality…
Last month, the U.S. Dept. of Energy (DOE; Washington, D.C.; www.energy.gov) awarded $3.2 million in funding for the Solar MEAD project, which aims to decarbonize cement production. This joint project is headed by Cemex, S.A.B. de C.V. (Cemex; Monterrey, Mexico;…
P-XYLENE FROM CO2 Last month, a Japanese consortium announced the successful production and purification of p-xylene produced from CO2 at pilot scale. The University of Toyama (www.u-toyama.ac.jp), Chiyoda Corp. (www.chiyodacorp.com) and HighChem Co., Ltd. (www.highchem.co.jp) have been collaborating on producing…
For the first time, a hydrocarbon-based membrane has passed the performance and durability testing standards set by the U.S. Dept. of Energy (DOE; Washington, D.C.; www.energy.gov) for heavy-duty fuel-cell applications. Typically, membranes in fuel cells are made of perfluorinated materials…
Chemical recycling of waste polyolefins is difficult to achieve economically partly because of the stability of carbon-carbon bonds in the plastics. In a new approach, researchers at Pacific Northwest National Laboratory (PNNL; Richland, Wash.; www.pnnl.gov) and the Technical University of…
Current electrolyzers for producing hydrogen use purified water as feedstock, but in the future, this could exacerbate freshwater shortages in some areas. Seawater is highly abundant, but the ions it contains undergo electrode side reactions, and cause corrosion in proton-exchange…
A new flow-battery design is based on quinones — a plentiful material historically derived from coal tar and used in dyestuff manufacturing — rather than traditional battery electrolytes. “Our feedstocks use no critical materials like lithium, cobalt or nickel, and…
