Chementator: Fuel from Rubber Seeds
In Malaysia, the raw material for biodiesel production has been palm oil. However, making biodiesel can conflict with the oil’s use as food, and growing palm oil (even for food) has caused the destruction of tropical forests in Borneo, Sumatra…
Chementator: Bioethanol
Fluxome Sciences A/S (Lyngby, Denmark; edlinks.chemengonline.com/5830-547) has been granted patents in both the U.S.and Europe for a method to improve bioethanol production by engineering the ammonia assimilation in yeast. By modifying the redox metabolism, it is possible to reduce the…
Chementator: Waste-to-oil
Last month, Clyvia Technology GmbH (Wegberg, Germany; edlinks.chemengonline.com/5830-548), a fully owned subsidiary of Clyvia Inc. (Las Vegas, Nev.), was granted a German patent for its proprietary fractional depolymerization process for converting waste material into heating oil and diesel fuel. The…
Chementator: Nanotube membranes
Researchers at the Lawrence Livermore National Laboratory (LLNL; Calif.; edlinks.chemengonline.com/5830-551) have constructed a membrane of carbon nanotubes (CNTs) on a silicone chip, which has the potential to reduce the energy costs of desalination by up to 75%, compared to conventional…
Chementator: Surface treatment
NexGen Technologies, LLC (Farmington Hills, Mich.; edlinks.chemengonline.com/5830-552) has commercialized a next-generation of engineered surface treatments that imparts wear-resistance, anti-galling, anti sieze and reduced friction to a wide range of substrates. The treatment process involves a proprietary plasma-delivery system operating at…
Chementator: OLED breakthrough
DuPont (Wilmington, Del.; edlinks.chemengonline.com/5830-553) has demonstrated the ability to print small-molecule OLED (organic light-emitting diode) materials from solution. The printing process is said more scalable to large-display sizes and substantially less expensive than alternative processes, such as vapor deposition. DuPont…
Chementator: A new reactor is set to change the way chemicals are produced
Alfa Laval AB (Lund, Sweden; edlinks.chemengonline.com/5830-531) has developed a new reactor system, called Alfa Laval Plate Reactors (trademarked as ART), which combines the high-heat-transfer capabilities of plate heat exchangers with the efficient mixing and reaction control typical of microreactors into…
Chementator: Sonocrystallization makes a salty spray
Sodium chloride aerosols are widely used as part of bronchial provocation tests to identify people with asthma, and those who wish to enter military or police service. To maximize their effectiveness, salt aerosol crystals should be as small as possible…
Chementator: A commercial debut for a process to make propylene oxide
At last month’s Achema conference (Frankfurt; May 15–19), Norbert Ullrich, chief engineer at Uhde GmbH (Dortmund, Germany; edlinks.chemengonline.com/5830-533) announced a first customer for and presented details about a new hydrogen-peroxide-based propylene oxide (HPPO) process, developed by Degussa AG (Düsseldorf, Germany;…
Chementator: Another ‘green’ process to make caprolactam
Professor Yasutaka Ishii, and colleagues from the Dept. of Applied Chemistry, Kansai University (Osaka, Japan; edlinks.chemengonline.com/5830-535), has developed a three-step production process to make epsilon-caprolactam (CPL) from cyclohexane. Compared to alternative methods, the process has a higher CPL yield, generates…
