Making liquid fuels from waste plastics
Gasoline-like fuel suitable for internal combustion engines can be obtained from the pyrolysis of plastic waste, according to a study conducted by a team of people from Gadjah Mada University (Yogyakarta, Indonesia; www.ugm.ac.id), University Sains Malaysia (Penang, Malaysia; www.usm.my), and…
Continuous crude-oil production from algae
Scientists at Pacific Northwest National Laboratory (PNNL; Richland, Wash.; www.pnnl.gov) have developed a continuous process for generating crude oil from algae that they believe can lower the cost of producing algae-based fuel. The process works by combining hydrothermal liquefaction and…
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…
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…
Novel co-catalyst system could enable CO2-to-syngas processes
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 adsorbent to recover uranium and other heavy metals from wastewater
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…
January Chementator Briefs
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…
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…
