A three-year research project to assess the effects of nanoparticles on people’s health and the environment started up last month. The project is coordinated by the Max Bergmann Center for Biomaterials (Dresden, Germany; edlinks.chemengonline.com/5829-538) with participation from companies and research…
First commercial results for a new reforming catalyst (R-98) of UOP LLC (Des Plaines, Ill.; edlinks.chemengonline.com/5829-545) were reported last month. Hunt Refining Co. (Tuscolaloosa, Ala.) has improved reformate yield from hydrotreated coker naphtha by about 2 vol.% since 2005, when…
Although citrus peels are rich in pectin, cellulose and hemicellusic polysaccharides, such waste products are currently marketed as low-value cattle feed, despite its relatively high processing cost, according to the ARS Citrus and Subtropical Products Laboratory (Winter Haven, Fla.; edlinks.chemengonline.com/5829-544).…
Sigma-Aldrich (St. Louis, Mo.; edlinks.chemengonline.com/5829-550) has commercialized an air- and water-stable palladium catalyst for performing intermolecular cross-coupling reactions, aminations and intermolecular Heck transformations. The catalyst, developed by Professor Michael Organ at York University (Toronto, Canada), is based on a Pd-NHC…
Mechanically driven diaphragm pumps (MDDPs) are widely used for metering applications in the chemical process industries. But because the pressure difference between the drive and the delivery side gives rise to tensile loads in the flexing zone of the diaphragm,…
In Anaheim, Calif., last month at the Parenteral Drug Assn.’s annual meeting, Pall Corp. (East Hills, N.Y.; edlinks.chemengonline.com/5829-539) introduced Ascotec to the global market, a faster, more accurate system for detecting microbial contamination in clean-room air systems. When compared to…
Fundamental to the chemical process industries (CPI) — whether specialty or bulk chemicals, pharmaceuticals, food products, minerals processing, environmental protection or other products or activities — is the need for mixing. The wide variety and complexity of mixing…
In today’s global marketplace, multinational companies are almost expected to manufacture products at different sites around the world. Try as they might to build plants that are identical and employ the same procedures, there are no guarantees the results will…
Although chemically identical to vegetation-derived cellulose, bacterial cellulose (BC) has a different tertiary structure, which imparts a number of unique — and commercially important — properties. For example, BC is nontoxic and biocompatible, and has a large water-holding capacity, which…
It is now fairly well established that mass- and heat-transfer efficiency, reaction selectivity and yield can be improved using microreactor technology (CE, July 2001, pp. 27–35). But the small channel dimensions (below one square millimeter) that are responsible for the…
