Bulk Solids Centers Support Research and Education
Bulk-solids handling is a critical aspect of many product manufacturing processes throughout the CPI, but the field is often underappreciated. Research centers that specialize in bulk-solids handling and particle technology are important resources for expanding knowledge and solving technical challenges…
Using a ‘green’ oxidizer to degrade Kraft lignin into vanillin
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 Basics
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…
A customized catalyst for solid-state reactions
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…
What Manufacturing Sites Can Learn from Municipalities About Water Loss
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…
Decarbonizing cement production using solar-thermal energy
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;…
Chementator Briefs
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…
A new milestone for durable fuel-cell membranes
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…
