Nanoparticles help generate hydrogen
A research team is using clusters of gold atoms at sub-nanometer sizes to enhance the photocatalytic production of hydrogen from water. Sustainable H2 production from a non-fossil-fuel source could have significant environmental and energy-efficiency benefits. The scientists, from Stony Brook…
Scale up planned for a new CO2-capture process
Plans are underway to field-test a process that removes more than 90 % of the carbon dioxide from power-plant flue gas, while reducing both the energy input and operating costs by 50 % compared to conventional amine-based CO2-scrubbing technology. The…
Membrane reactor may reduce wastage of natural gas
A small-scale ceramic membrane reactor to convert natural gas to transportable liquids in a single step is being developed by Ceramatec, Inc. (Salt Lake City, Utah; www.ceramatec.com) under a $1.7-million grant from the U.S. Dept. of Energy’s Advanced Research Project…
Using sunlight to incorporate CO2 into alpha-amino ketones
The research group of Masahiro Murakami at Kyoto University (Kyoto, Japan; www.sbchem.kyoto-u.ac.jp/murakami-lab) have synthesized a promising pharmaceutical precursor using only sunlight (as energy source) and CO2 (as co-reagent). The solar-driven process involves two consecutive reactions (diagram): first, light transforms an…
A starch-based cationic polymer for oil recovery
Cationic polymers have been used in the petroleum industry as shale-control agents, demulsifiers, blocking agents, and filtrate reducers for drilling fluids, but process complexity and high cost have limited their application. Now researchers from Zhejiang Normal University (Jinhua; www.zjnu.edu.cn) and…
A new photocatalyst for VOC destruction
A process for manufacturing fine particles of titanium dioxide that exhibits a high level of photocatalytic activity has been developed by Showa Titanium Co., a subsidiary of Showa Denko K.K. (SDK, Tokyo; ww.sdk.co.jp). The product has been developed in collaboration…
December Chementator Briefs
Rotary atomizer Engineers at Dedert Inc. (Homewood, Ill.; www.dedert.com) have developed a high-speed rotary atomizer for a spray-dryer system that features a motor with permanent rare-earth-metal magnetic bearings. The centrifugal rotary atomizer can achieve peripheral speeds 30 to 40%…
A boost for bio-butanol production
Lately there has been much renewed interest in fermentative production of n-butanol from renewable biomass as an industrial solvent and liquid fuel superior to ethanol that could be used as a substitute for gasoline. An improved butanol production through the…
Scaleup for a microbial process that produces acetic acid from offgases
A demonstration plant for the production of acetic acid from the carbon dioxide in industrial offgases will be built at an operating plant of Petronas (Kuala Lumpur; www.petronas.com.my), Malaysia’s national oil company, under an agreement with LanzaTech (Roselle, Ill.; www.lanzatech.com),…
A new way to obtain hydrogen from heavy oil
The volume of heavy, sour crude oil processed by North American refineries is steadily increasing, and along with it a commensurate demand for hydrogen to upgrade that oil. A steam-reforming process that would allow refiners to produce their own H2…
