Chemists from the University of California, Berkeley (UC Berkeley; www.berkeley.edu) have modified a metal-organic framework (MOF) compound with diamines, which enables the material to be tuned to absorb CO2 at different temperatures, such as from air at room temperature, or…
Industrial CO2 capture is currently done by absorption in liquid amines, such as monoethanolamine. However, absorption-based carbon capture carries a significant energy penalty for regenerating CO2 in a stripping column — power plants can lose 20–30% of their energy output…
Last month, Hydro ASA (www.hydro.com) entered into a contract with Multiconsult (both Oslo, Norway; www.multionsult.no) for engineering services for Hydro’s planned pilot plant at Karmøy, Norway. The Karmøy pilot aims to verify what Hydro calls the worlds most energy- and…
The research group of Yuya Tachibana at Gunma University (Gunma, Japan; greenpolymer.chem-bio.st.gunma-u.ac.jp) has developed a procedure for the production of terephthalic acid (TPA), the monomer of the widely used thermoplastic polymer polyethylene terephthalate (PET), from the inedible biomass-derived starting material…
XstalBio Ltd. (Glasgow, U.K.; www.xstalbio.com) has recently been issued a patent (US 8,932,715) covering the use of precipitation-stabilizing additives for the manufacture of dry powders of therapeutic proteins, including monoclonal antibodies (mAbs). Compared to lyophilization, the XstalBio precipitation process offers…
Earlier this year, Asahi Kasei Chemicals Corp. (Tokyo, Japan; www.asahi-kasei.co.jp/chemicals) has developed a new process for making diphenyl carbonate (DPC), a monomer used for making polycarbonate (PC) resins. This new route to DPC uses only an alcohol, phenol and CO2…
This summer, GFBiochemicals Green Future S.r.l. (Milan, Italy; www.gfbiochemicals.com) will start commercial-scale production of bio-based levulinic acid using its proprietary, continuous-production process. The company says it will produce 2,000 metric tons per year (m.t./yr) at its plant in Caserta, Italy…
Photosynthesis is one of the best ways to convert carbon dioxide into renewable energy and at the same time, reduce the concentration of CO2 in the atmosphere. In plants, there are two main steps in photosynthesis: First, water is split…
Last January, Haldor Topsøe A/S (Lyngby; www.topsoe.com) and FLSmidth A/S (Copenhagen, both Denmark; www.flsmidth.com) began a joint, global effort to commercialize a new catalytic filter-bag technology, which the partners have developed over the past four years. Tradenamed EnviroTex, these filter…
Two new proton-exchange-membrane (PEM) electrolysis systems have debuted, targeting applications that require large volumes of hydrogen. Prior to the launch of Proton OnSite’s (Wallingford, Conn.; www. protononsite.com) M1 and M2 modular H2-generation systems, the largest capacity commercially available from PEM…
