A process that is expected to produce high-octane gasoline from non-food biomass for an average cost of $1.50/gal, depending on feed costs, will be commercialized by Cool Planet Energy Systems (Denver, Colo.; www.coolplanet.com). The company has tested the process in a 200,000-gal/yr pilot plant in Camarillo, Calif., and now plans to install 400 10-million-gal/yr microrefineries across the U.S. by 2020...

A typical fluid catalytic cracking unit (FCC) generates about 200 tons/d of dry gas — a mixture of off-gases that is burned as refinery fuel. However, about 40 tons of that gas is ethylene, which would have much greater value as gasoline or diesel fuel. A process that converts better than 40% of the ethylene to motor fuels in a single pass is being developed by UOP LLC, a Honeywell...

  Anti-hydrolysis agent Teijin Ltd. (Tokyo, Japan; www.teijin.co.jp) has developed a new carbodiimide anti-hydrolysis agent that is said to exhibit “superior” anti-hydrolysis properties to improve the durability of plastics. The agent has the additional advantage of not emitting isocyanate gas, which is usually generated during the use of carbodiimide agents. Thus, the new agent is...

New technology developed for air-operated, double-diaphragm (AODD) pumps can reduce consumption of compressed air by up to 60% without electronic components, while maintaining the same flowrates. The reduced air consumption translates directly to lower energy usage. Developed by Wilden Pump Inc. (Grand Terrace, Calif.; www.wilden.com), and tradenamed the Pro-Flo Shift Air Distribution System, the...

Scientists from the Chinese Academy of Sciences (Beijing; www.cas.ac.cn) have found a way to transform polyurethane (PU) foam into a sponge that is strongly water-repellent and oil-absorbing, making it suitable for soaking up chemicals and petroleum from spills. One of the Chinese scientists, Zhaozhu Zhang, says that sponges previously developed to absorb oil from spills also soak up water as well, so...

NEDO  and Hitachi Ltd. (Tokyo, www.hitachi.com) have developed a new combustion technology that could reduce the emissions of oxides of nitrogen (NOx) to below 10 ppm without the addition of diluents. As part of the CCS-IGCC project (carbon capture and storage — integrated coal gasification, combined cycle)...

  ODC for Cl2 production Last month, ThyssenKrupp Uhde GmbH (Dortmund; www.uhde.eu) and Bayer MaterialScience AG (BMS; Leverkusen, both Germany; www.bayermaterialscience.com) commercially launched — worldwide — the oxygen depolarized cathode (ODC) technology, which BMS and ThyssenKrupp Uhde/UhdeNora developed to improve the efficiency of membrane chlor-alkali plants. By replacing the...

In April development tests, Cobalt Technologies (Cobalt; Mountain View, Calif; www.cobalttech.com) produced n -butanol at the fermentation scale of 100 m3 per run, demonstrating lower production cost than butanol produced from petroleum. This represents production that is a factor of 10 larger than previous trials conducted at the National Renewable Energy Laboratory (NREL; Golden, Colo.; www.nrel.gov)...

To comply with increasingly stringent regulations for NOx emissions, operators of industrial plants often turn to low-NOx burners to avoid much more costly post-combustion treatment approaches like selective catalytic reduction (SCR). But low-NOx burners are plagued by significant losses in efficiency and process throughput. ClearSign Combustion Corp. (Seattle, Wash.; www.clearsign.com) has developed...

A process that uses magnetic nanoparticles, coated with a reactive material, to clean up contaminated water for human use is being developed at Stanford University (Stanford, Calif.; www.stanford.edu). The nanoscavengers, as they are called, are distributed in the water to kill pollutants, then are recovered magnetically for re-use. Stanford’s particles are...

Ammonia is a promising candidate for scrubbing carbon dioxide from fluegas, since each ammonia molecule can absorb one molecule of CO2, whereas amine absorbers require two molecules to do the same job. However, because ammonia is volatile, the fluegas must be cooled to about 10°C. This requires a lot of electrical energy, points out Indira Jayaweera, a senior staff scientist with SRI International...

Freestanding nanowires exhibit ultrahigh elastic-strain limits (of up to 7%) and yield strengths. However, it has been difficult to exploit their properties in bulk composites, due to the mismatch between the elasticity of the nanowires and the elasticity of the metals that form the matrix. The nanowires will experience an elastic deformation of several percent, but normally the metals that form the matrix...

Squalane, an emollient used in cosmetics, will be the first product of a biotechnology pilot plant now being started up by Nucelis Inc. (San Diego, Calif.; www.nucelis.com), a spin-off from Cibus (also of San Diego). The plant will use Cibus’ Rapid Trait Development System (RTDS), a new gene-editing technology, to enable naturally occurring yeast to increase their production of squalene, the...
