A new low-temperature shift catalyst passes longterm testing
A new water-gas shift catalyst has undergone 1,000 h of successful operation in a demonstration carried out by the New Energy and Industrial Technology Development Organization (NEDO, Kawasaki; www.nedo.go.jp) and Hitachi, Ltd. (Tokyo, both Japan; www.hitachi.com). The tests were performed…
Rare-earth magnets enhance filtration of engine lubricants
FilterMag International (Scottsdale, Ariz.; www.filtermag.com) has developed neodymium magnetic devices that can boost the performance of lubricant filters for mining vehicles and industrial machinery. When the device is in place, filters retain 50–75% of contaminant particles that would otherwise be…
A sorption-enhanced catalyst improves CO2 methanation
Converting CO2 into methane is a way to mimic the natural carbon cycle and close the energy cycle by producing synthetic hydrocarbons (see, for example, CO2 Utilization, Chem. Eng., July 2013, pp. 16–19). However, the Sabatier reaction (CO2 + 4H2…
This catalyst system requires significantly less palladium
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…
Bacteria and algae team-up to tackle arsenic-contaminated water
Australian researchers have developed a method of cleaning arsenic out of contaminated water by combining the effects of bacteria and microalgae. Professor Megh Mallavarapu and his team, from the Cooperative Research Center for Contamination Assessment and Remediation of the Environment…
Advanced battery electrolytes made with low-cost, high-throughput method
A high-throughput method for synthesizing ionic-liquid-containing electrolytes developed by Boulder Ionics Corp. (Arvada, Colo.; www.boulderionics.com) has been refined to enable its use in commercial production. Boulder Ionics had previously piloted the continuous process for producing advanced ionic-liquid (IL) electrolytes at…
This graphite burner enables on-demand treatment of offgases
Offgases containing compounds of chlorine or fluorine are typically burned to enable the recovery of HCl or HF and prevent release into the environment. However, conventional combustion chambers require a long time to heat up, and thus are typically run…
Bacteria make lactic acid from palm waste
Extraction of palm oil generates large amounts of lignocellulose-rich byproduct known as empty fruit bunch (EFB), which is usually wasted. A new process for utilizing this waste to make lactic acid has been developed by a team of researchers in…
A two-step process that makes phenols from lignin
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 efficient cycle for utilizing waste heat
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…
