METAL-FREE ATRP
Atom transfer radical polymerization (ATRP) is a relatively new process to form carbon-carbon bonds of well-defined polymers. Since its discovery in 1995, ATRP has been performed using transition-metal complexes, such as those of copper. This feature has limited the application…
BIO SNG PILOT
Construction has been completed on a trailer-mounted pilot plant that will produce substitute natural gas (SNG) from the products of biomass gasification (H2, CO2 and CO). Built by researchers from the Karlsruhe Institute of Technology (KIT; www.kit.edu) as part of…
Synthesizing adipic acid without generating N2O
Adipic acid, a precursor for the synthesis of nylon, is usually produced through nitric acid oxidation of cyclohexane, a process which has disadvantages, such as the emission of nitrous oxide — a greenhouse and ozone-depleting gas — as well as…
Electrode design increases efficiency of suspended-solids removal
A specially designed electrode could improve the efficiency of removing suspended solids, oil or other contaminants from water in applications traditionally served by dissolved-air flotation (DAF). Developers at OriginOil Inc. (Los Angeles, Calif.; www.originoil.com) believe their electrolysis process overcomes limitations…
A bio-based crosslinker for polyurethanes
At the European Coatings Show (April 21–23; Nuremberg, Germany), Bayer MaterialScience AG (BMS; Leverkusen, Germany; www.materialscience.bayer.com) will launch Pentamethylene diisocyanate (PDI), a new isocyanate with 70% of its carbon content originating from biomass. The eco-friendly hardner component is being evaluated…
A step closer to making CO by artificial photosynthesis
Researchers at Toshiba Corp. (Tokyo, Japan; www.toshiba.co.jp) have developed an artificial photosynthesis system that uses solar energy to convert CO2 and water into CO with 1.5% efficiency — the highest efficiency achieved to date. The company believes the technology has…
A highly efficient heterogeneous catalyst for making THF and other chemicals from biomass
The research group of Keiichi Tomishige at Tohoku University (Sendai, www.che.tohoku.ac.jp/~erec), in collaboration with Daicel Corp. (Tokyo, both Japan; www.daicel.com/en), has developed a catalytic reaction system that is highly efficient for synthesizing tetrahydrofuran (THF) — a widely used solvent and…
Reduce maintenance of high-pressure pumps
In hydraulic fracturing, high-pressure pumps force water bearing sand or ceramic proppants into a manifold, known as a missile, and subsequently into an oil or gas well. Exposure to the highly abrasive, proppant-filled fluids means the pumps require frequent maintenance…
Xylenes-production process takes advantage of low-cost methanol feedstock
A new low-pressure xylenes-production process combines toluene with methanol to yield a xylenes product stream with the possibility of no benzene byproduct. Known as GT-TolAlk and developed by GTC Technology (Houston; www.gtctech.com), the new process requires no hydrogen addition and…
3-D Printing Accelerates, Creating CPI Opportunities
Activity in standards development, industry initiatives and R&D are fueling the growth of additive manufacturing (3-D printing) technology in industry The field of additive manufacturing (AM) — often referred to as three-dimensional (3-D) printing — has seen explosive growth in…
