Professor Takao Masuda and colleagues at Hokkaido University (Sapporo; www.eng.hokudai.ac.jp/labo/cse), in collaboration with Idemitsu Kosan Co. (Idemitsu; Tokyo; both Japan; www.idemitsu.com), have developed a two-step process that converts wood-based lignin into phenols. They believe the achievement could lead to an…
An Australian team has implemented several changes to the conventional organic rankine cycle, resulting in a highly efficient regenerative thermodynamic cycle for producing electricity from waste heat and other thermal sources. The University of Newcastle’s Priority Research Center for Energy…
A metal-free catalyst system involving ionic liquids and doped carbon nanofibers can efficiently reduce carbon dioxide to carbon monoxide, offering a cost-effective electrochemical route from CO2 to synthesis gas (syngas), and further, to liquid transportation fuels. A research group at…
A new method for removing uranium and other heavy metals (HMs) from wastewater has been developed by researchers at the University of Eastern Finland (Joensuu; www.uef.fi). The technology has been licensed by Oy Chemec AB (Espoo, Finland; www.chemec.fi), which plans…
Sludge dewatering Last month, Metso Corp. (Helsinki, Finland; www.metso.com) introduced what it claims to be the worlds first advanced solution — both measurements and control system — to optimize sludge dewatering at wastewater treatment plants. The Metso SDO (sludge…
A stabilized palladium catalyst system that can be used for making materials for organic solar cells and pharmaceuticals has been developed by the research groups of of Yoichi Yamada at Riken (Wako city; www.riken.jp) and Shigenori Fujikawa at the International…
Acetic acid from syngas A new process for the production of acetic acid claims to be more efficient and cost-effective than current technologies. Carbonylation of methanol has been the leading acetic acid technology for several decades, but BP plc…
The effluent discharged by domestic industries in Japan amounts to approximately 11.1 billion ton/yr. Most of this waste is comprised of relatively low concentrations of organic matter. Today, most of this effluent is treated by aerobic biotreatment (activated sludge). However,…
A research team from the University of Western Australia (Perth; www.uwa.edu.au), led by professor Dongke Zhang, has pioneered the application of higher plants for new-generation biofuel production. Metabolic engineering of Arabidopsis thaliana — a small flowering plant native to Europe…
Petroleum refineries generate power from a number of sources, including cogeneration plants and steam networks. Generally, steam networks use turbines to improve operational reliability, specifically as drivers for rotating equipment. Due to increasing energy costs, it is essential to maximize…
