A car company moves closer to making cellulosic ethanol ecomomically
Using gene recombination technology, Toyota Motor Corp. (TMC; Toyota City, Japan: www2.toyota.co.jp/en) has developed a new strain of yeast that achieves one of the highest ethanol-fermentation density levels in the world — approximately 47 g/L with 87% yield (based on…
Control the fuel-to-air ratio in combustion with varying fuels
In combustion, the ratio of fuel to air is key to efficiency, emissions control and stable performance of the combustion system. Adjusting this ratio to accommodate variability in fuels — due to the use of different fuels, and the variability…
Commercialization is set for a new alkylation process
An improved sulfuric-acid alkylation process that reduces acid consumption by up to 50% from that of conventional processes will make its commercial debut in China. Developed by Lummus Technology, a CB&I company (The Woodlands, Tex.; www.cbi.com), the technology will be…
Detecting steam-trap leaks gets easier
Steam traps are designed to allow condensate, but not steam, to escape from a steam line. When they malfunction, however, numerous costly consequences can result including energy losses, insufficient heating to processes, maintenance issues and more. At its Global Users…
Recover oil from messy spills with this mesh
A novel mesh for oil-water separation with opposite wettability to traditional materials has been developed by a group of researchers from Beijing, China — the Beijing National Laboratory for Molecular Sciences, Institute of Chemistry, Chinese Academy of Sciences (www.iccas.ac.cn); School…
An in-pipe turbine system generates energy from water effluent
Hydrofoil turbines mounted inside gravity-fed water-effluent conduits can generate significant electrical power without impeding flow, a demonstration project has shown. The in-pipe turbine systems offer chemical process industries (CPI) companies a way to extract emission-free energy from flowing wastewater discharge…
Making formic acid by artificial photosynthesis
For the first time, an organic compound has been synthesized from water, carbon dioxide and sunlight — without any other external energy or reagents. The achievement, which was demonstrated by researchers at Toyota Central Research and Development Laboratories, Inc. (Toyota…
World’s highest-purity lithium plant announces commercial launch
A facility that produces high-purity lithium carbonate for use in the growing market for electrolytes in electric-vehicle batteries has begun commercial operations in Imperial Valley, Calif. The 500-ton/yr plant, operated by Simbol Materials (Pleasanton, Calif.; www.simbolmaterials.com), is the only producer…
Supercritical water process converts biomass to sugars
Sugar is a critical feedstock for many emerging bio-based-chemical and biofuel processes, but harvesting sugar from low-value, nonfood biomass cost-effectively and at large scale remains a challenge. Renmatix Inc. (King of Prussia, Pa.; www.renmatix.com) has developed a process that uses…
November Chementator Briefs
New block copolymer Nexar is the tradename of a block copolymer product recently commercialized by Kraton Performance Polymers (Houston; www.kraton.com) that has unique water-transport properties. Building on its earlier work in anionic polymerization of styrene-butadiene block copolymers, the company…
