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),…
This filtration system saves space, time and money
In the production of deionized (DI) water from river water, sand filters are commonly used to remove solid particles prior to the ion-exchange units. However, sand beds occupy a large space — as large as 3-m wide and over 5-m…
Two technologies combined to treat oil and gas wastewater
A partnership between New Sky Energy (Boulder, Colo.; www.newskyenergy.com) and 212 Resources (Houston, Tex.; www.212resources.com) combines the two companies’ technologies to generate freshwater and usable inorganic chemicals from produced water in petroleum and natural-gas drilling operations. 212 Resources…
A new catalyst enables lower-temperature H2 production using the sulfur-iodine cycle
Among the many different ways being investigated for making hydrogen “from water” is the so-called sulfur-iodine (S-I) cycle, which involves three chemical reactions whose net products are H2 and O2: the decomposition of sulfuric acid into SO2, H2O and O2;…
Quick-charging lithium ion batteries on the horizon
Conventional lithium-ion batteries (LIBs) are unsuitable for high power applications as in electric vehicles, because they take a long time to charge, according to a team from the Interdisciplinary School of Green Energy, of the Ulsan National Institute of Science…
Odor control in small doses
A team headed by professor Zhiguo Yuan, from the Advanced Water Management Center, University of Queensland (Brisbane, Australia; www.awmc.uq.edu.au) claims to have developed a new method for corrosion and odor control in sewers that is more cost-effective and environmentally friendly…
Demonstration for a process that makes H2 from sewage sludge
Japan Blue Energy Co. (JBEC; Tokyo, Japan; www.jpo-net.co.jp), Daiwa Lease Co., Toyota Tsusho Corp., and Mitsui Chemicals, Inc. have established the Business Research Group of Hydrogen Innovation Town (BRG-HIT) to start verification tests for a new technology for making hydrogen…
Chementator briefs
Water treatment The recently introduced FoodPro ST line of water-treatment chemicals from GE Power & Water (Trevose, Pa.; www.ge.com) prevents corrosion and scale in stainless-steel sterilizers and pasteurizers in the food and beverage industry, and they are less expensive than…
Microbial processing of ore
Extraction of metals, such as lithium, from laterite ores is usually carried out through solubilization of metals by acids, such as sulfuric and hydrochloric acids. However, substantial metal recoveries from laterites have been achieved only through thermal pre-treatment of laterites,…
