This ceramic membrane converts natural gas to liquid hydrocarbons
Converting natural gas to liquid hydrocarbons can theoretically be accomplished at high temperatures with the help of zeolite catalysts, but the reaction is hindered by two major factors. The conversion to products is thermodynamically limited, and coke formation on the…
Purify p-xylene without the heat
Current commercial technologies for separating and purifying p-xylene — an important precursor for polyesters and plastics — from hydrocarbon mixtures involve phase-change techniques that require large amounts of thermal energy. Recently, a research team from Georgia Institute of Technology (Ga.…

Making CO from CO2Professor Rhosuke Suzuki at Hokkaido University (Sapporo City, Japan; www.eng.hokudai.ac.jp) has developed a molten-salt electrolysis process that can produce CO from high temperature CO2 present in the fluegas of industrial furnaces. The process uses a molten salt…
Catalytic process converts sorted waste into aromatic compounds
The rising cost of landfilling trash creates a strong incentive to utilize the waste for saleable products. A recently piloted process is an example: the process can convert municipal solid waste (MSW) into a narrow range of valuable aromatic compounds.…
Control biofouling with I2-vapor disinfection
A patented technology for infusing bubbles of elemental iodine into fluid or air can reduce microbial counts and potentially eliminate surface biofilms. Originally developed to remove biofilms from water lines in the dental industry, the technology is being used as…
This coating makes glass into a solar panel
A layered coating that acts as an organic semiconductor material allows building windows to generate electricity from direct, indirect, shaded, diffused and reflected sunlight, as well as from artificial light. Developer SolarWindow Technologies Inc. (Columbia, Md.; www.solarwindow.com) has designed and…
Engineering bacteria to make muconic acid
Researchers at the Agency for Science, Technology and Research (A*STAR; Singapore; www.a-star.edu.sg), led by Sudhakar Jonnalagadda, have provided another step toward replacing petrochemicals with renewable resources in the manufacture of synthetic fibers and plastics. The team has genetically modified Escherichia…
Recover chemicals from sugarcane bagasse using the half the energy
Last month, the New Energy and Industrial Technology Development Organization (NEDO; Kawasaki, Japan; www.nedo.go.jp) signed a Memorandum of Understanding (MOU) with the National Innovation Agency (NIA; Bangkok, Thailand; www.nai.or.th) to work jointly on a project to demonstrate a manufacturing system…
Redox Flow Batteries Charge Forward
Developments in redox flow batteries are moving at a tremendous pace to meet the growing need for large-scale energy-storage systems, which are used for stabilizing electric power distribution The global energy-storage market is expected to double, from 1.4 GWh added…
