Tiny Fe-Ni batteries accelerate soil decontamination
Soil contaminated with chlorinated aliphatic compounds can be remediated ten times faster than with biological or iron-based methods by use of a new metallic powder developed by Tosoh Corp. (Tokyo; edlinks.chemengonline.com/6514-532). The powder, called MA-FN20, electrochemically strips the chlorine atoms…
NH3-based CO2 capture to be field tested
Powerspan Corp. (Portsmouth, N.H.; edlinks.chemengonline.com/6514-535) is developing a process that uses an aqueous ammonia (AA) solution to capture COâ‚‚ from the fluegas (FG) of power plants. Results from a joint research project with the U.S. Dept. of Energy’s (DOE; Washington,…
Making pure hydrogen from biomass
Professor emeritus Kiyoshi Ohtsuka and his colleagues at the Tokyo Institute of Technology, Tokyo, Japan; edlinks.chemengonline.com/6514-538) have discovered a new process that produces pure Hâ‚‚ from cellulose. The process not only has nearly a 100% yield, but produces no CO…
Chementator: Mercury removal
Battelle (Columbus, Ohio; edlinks.chemengonline.com/5830-544) has licensed the Samms technology, developed at Pacific Northwest National Laboratory (PNNL; Richland, Wash.), to Steward Environmental Solutions (Chattanooga, Tenn.; edlinks.chemengonline.com/5830-545). Samms (self-assembled monolayers on mesoporous supports) is a technology that can be tailored to selectively…
Chementator: A continuous route to HI generates less effluent
Nippoh Chemicals Co. (Tokyo; edlinks.chemengonline.com/5830-539), is developing a continuous, vapor-phase process to produce hydroiodic acid as an alternative to the conventional liquid-phase batch process. Over the next few months, the company will test the new process in a 30-m.t./yr pilot…
Chementator: Bioethanol
Fluxome Sciences A/S (Lyngby, Denmark; edlinks.chemengonline.com/5830-547) has been granted patents in both the U.S.and Europe for a method to improve bioethanol production by engineering the ammonia assimilation in yeast. By modifying the redox metabolism, it is possible to reduce the…
