Bio-isoprene Yokohama Rubber Co. (Tokyo, Japan; www.yokohama.com) has developed what is said to be the world’s first technology capable of efficiently producing isoprene from biomass. The new breakthrough is the result of joint research with Riken (www.riken.jp) and Zeon Corp.…
Solvent-free recovery of plant-based extracts
Plant-based extracts, such as antioxidants, phytochemicals and polyphenols, are used in a number of end-markets, including cosmetics, foods and nutritional supplements. A proprietary, low-polarity, pressurized-water extraction method is set to drastically improve the recovery of useful ingredients from botanical sources.…
New phosphoric acid process expands available resources
Almost all phosphoric acid is produced via the wet-acid process (WAP), which requires relatively pure raw materials and produces large volumes of a potentially hazardous, special waste called phosphogypsum, which is highly regulated in terms of storage and disposal. A…
HF alkylation unit converted for solid-bed alkylation of LAB
In a first-of-its-kind endeavor, a hydrogen-fluoride-based alkylation unit producing linear alkyl benzene (LAB) is being converted into a solid-bed alkylation unit that employs UOP’s (Des Plaines, Ill.; www.uop.com) Detal-Plus alkylation technology for LAB. LAB is used in the production of…
Vacuum-aided membrane distillation results in ultra-pure water
At Achema 2018 (June 11–15; Frankfurt am Main, Germany), EvCon GmbH (Pliening-Landsham, Germany; www.evcon-water.com) showcased its new UPWater treatment system, which employs a patented vacuum multi-effect membrane distillation (VMEMD) technology to obtain ultra-pure water using less energy than comparable water-treatment…
Fuel-cell solution lowers operating costs using nanostructured catalysts
The two main barriers to widespread use of fuel cells have been securing a reliable source of hydrogen that avoids CO2 emissions, and cost — they have traditionally depended on expensive platinum and palladium catalyst materials. GenCell Energy Ltd. (Petach…
Advanced water electrolysis launched
Last month, thyssenkrupp Industrial Solutions AG (Dortmund, Germany; www.thyssenkrupp-industrial-solutions.com) launched industrial-scale water electrolysis systems that make large-scale hydrogen production from renewable electricity economically attractive. The advanced water electrolyzer (diagram) features a well-proven cell design paired with an especially large (2.7…
The commercial launch of 3-D-printed membranes
Last month, Nano Sun, a water technology start-up founded by a scientist from Nanyang Technological University (NTU; Singapore; www.ntu.edu.sg) launched a 3-D-printing facility to manufacture a new type of water-treatment membrane. Unlike conventional membrane-manufacturing processes, which use acids to make…
