Membrane extraction improves biofuel yield
Typically, the production of fuel-grade chemicals, such as butanol, from biomass fermentation processes involves low-yield batch processes and high energy costs. Now, researchers from Imperial College London (ICL; www.imperial.ac.uk), in partnership with bp plc (London; www.bp.com), have demonstrated a new…
January Chementator Briefs
MDI Production Late last year, Covestro AG (Leverkusen, Germany; www.covestro.com) started up a pilot plant for the production of methylene diphenyl diisocyanate (MDI) based on the innovative AdiP (adiabatic-isothermal phosgenation) technology at its Brunsbüttel site. The new technology promises to…
Methane pyrolysis process uses renewable electricity to split CH4 into H2 and carbon black
Site commissioning is underway at a facility in Nebraska that uses plasma pyrolysis to generate hydrogen gas and carbon black from natural gas without any local carbon dioxide emissions. The developer, Monolith Materials (Lincoln, Neb.; www.monolithmaterials.com), scaled up the process…
This additive reverses the effects of aging in recycled asphalt pavement
A new rejuvenator technology aims to improve the chemistry and service life of recycled asphalt pavement (RAP). The Invigorate additive, developed by Colorbiotics (Ames, Iowa; www.colorbiotics.com) based on Iowa State University research (www.iastate.edu), helps overcome issues with asphaltene aggregation and…
Sustainable graphite pilot project kicks off in Canada
A new project in Canada will build a pilot facility to demonstrate a carbon-neutral production strategy for battery-grade graphite materials. Nouveau Monde Graphite (Saint-Michel-des-Saints, Québec, Canada; www.nouveaumonde.ca) has signed an agreement with Olin Corp. (Clayton, Mo.; www.olin.com) to construct two…

DESALINATION The challenge for large-scale desalination is to improve the performance of membranes used for reverse osmosis. One promising method is to introduce artificial water channels (AWCs) into synthetic membranes, to imitate the aquaporins of biological proteins for transporting water.…
Endress+Hauser establishes internet security standards
The cryptography working group within the Internet Engineering Task Force (IETF; Fremont, Calif.; www.ieft.org) standards organization has chosen the CPace protocol — developed by Endress + Hauser AG (Reinach, Switzerland; www.endress.com) — as a recommended method for use in internet…
Graphene-oxide filtration membrane for harsh chemical environments
Filtration is being investigated as an alternative to thermal separation methods (such as distillation and evaporation) in many applications because of the potential energy savings, but conventional filtration membranes, such as those used in water desalination, are often not robust…
Nanoengineered catalysts can upcycle polyethylene
Drawing inspiration from the enzymatic breakdown of macromolecules in cellular systems, scientists at Ames Laboratory (Ames, Iowa; www.ameslab.gov) have developed a nanostructured catalyst that can break down high-density polyethylene (HDPE) and other polyolefins into a narrow distribution of diesel- and…
This nanoengineered catalyst converts mixed, impure waste to biodiesel
In an example of a biologically inspired and nano-engineered catalyst, researchers at RMIT University (Melbourne, Australia; www.rmit.edu.au) have developed ceramic catalyst particles with a porous network organized hierarchically, where one chemical reaction takes place within larger pores, while a second…
