A continuous fermentation process for making biologically derived butanol from a variety of sugar feedstocks is operating at what developers call “lab-pilot” scale, producing 2.5 liters per day. Engineering studies conducted by the research team forecast that it could be…
Iron ore is traditionally pelletized using the binding agent bentonite to facilitate transport and handling. A new additive for pelletizing iron ore significantly reduces the volume of binding agent required, while improving pellet strength and production output. Developed by Clariant…
The research group of Yasuhiro Uozumi and Yoichi Yamada at Riken (Saitama, Japan; www.riken.jp), in collaboration with professor Audrey Moores of McGill University (Montreal, Que.), has developed a highly efficient catalyst for performing hydrogenation reactions, which are important in the…
A pilot plant will be established at the University of Newcastle (Newcastle, Australia; www.newcastle.edu.au) to test a new technology for the sequestration of CO2 through mineral carbonation — the reaction with magnesium silicate minerals, such as serpentine, to form mineral…
Fermenting sugar is at the heart of many bio-based chemical and biofuel processes, but obtaining sugars from cellulosic biomass at low cost is an ongoing challenge. A new process using a reusable solid catalyst is capable of breaking down a…
When coal-derived synthesis gas (syngas) is converted to liquid fuel by the Fischer-Tropsch (F-T) process, the initial product is mostly straight-chain waxy paraffins that can be upgraded by hydroprocessing to obtain diesel fuel and naphtha, which are used for gasoline…
Researchers at the University of California Irvine (UCI, Irvine CA; www.chem.uci.edu) have taken a cue from nature in devising a way to remove carbon dioxide from fluegas. They are developing a synthetic membrane based on the design and function of…
AMT International Inc. (Plano, Texas; www.amtintl.com) and LG Chem, Ltd. (Seoul, Korea; www.lgchem.com) have successfully converted an existing sulfolane liquid-liquid extraction (LLE) unit at LG Chem’s Yeosu plant using a new extractive-distillation (ED) process for aromatics recovery. This technology was…
Cement manufacturing is a major source of greenhouse gas emissions due to two factors: carbon dioxide is released when calcium carbonate calcines to lime (CaO) in the cement manufacturing process; and cement kilns are operated at temperatures of 1,500°C, which…
The selective, one-step biocatalytic hydroxylation of benzene to phenol — at ambient pressure and temperature — has been demonstrated by professors Yoshihito Watanabe and Osamu Shoji at Nagoya University (Nagoya, Japan; bioinorg.chem.nagoya-u.ac.jp). The achievement was made using a wild-type of…
