January Chementator briefs
New cellulase enzyme Last month, Codexis, Inc. (Redwood City, Calif.; www.codexis.com) introduced the CodeXyme Cellulase enzyme product line for converting biomass to sugar. The company is in its final stages of customizing the enzymes with currrent partners, and plans…
This gold catalyst takes the crown for high activity and selectivity
Gold catalysts have been shown to have superior activities for oxidation reactions, especially at low temperature, compared to other metal-based catalysts. But the high price of gold makes it necessary to develop Au catalysts with ever-higher activities, reducing the amount…
PDVSA will commercialize a heavy-oil upgrading process
Venezuela’s state-run petroleum company, PDVSA Petroleo, S.A. (PDVSA, Caracas; www.pdvsa.com), will commercialize a company-developed process for upgrading heavy crude oil in its Puerto La Cruz refinery, about 300 km (190 miles) east of Caracas. The 210,000-bbl/d plant will employ PDVSA’s…
Demo plant for high-yield biomass-to-gasoline process under construction
Construction of a demonstration plant has begun for a biomass-to-gasoline process that boosts biomass conversion efficiency in producing bio-gasoline. The demonstration, to be located at the Hillsborough, N.J. headquarters of Primus Green Energy (www.primusge.com), is slated for completion in the…
This distillation column promises substantial energy reductions
A new distillation system capable of reducing energy consumption by up to 50% compared to conventional columns has been developed by Toyo Engineering Corp. (Toyo; Chiba, www.toyo-eng.co.jp), in collaboration with the National Institute of Advanced Industrial Science and Technology (AIST;…
December Chementator Briefs
Bio bisabolene Through genetic engineering of microbes, scientists from Lawrence Berkeley National Laboratory’s (Berkeley, Calif.; www.lbl.gov) Joint BioEnergy Institute (JBEI) have coaxed both bacteria (Escherichia coli) and yeast (Saccharomyces cerevisiae) to produce a chemical precursor to bisabolane — a critical…
Heat-exchanger ‘fusion’
Last month at the Brau Beviale 2011 Exhibition (November 9–11; Nuremberg, Germany), Alfa Laval AB (Lund, Sweden; www.alfalaval.com) launched a new plate heat exchanger, which combines the energy efficiency, accessibility and modularity of plate technology with the viscous and particulate-handling…
Making amides with high yield, less waste
A catalyst for making amides from alcohols and amines under aerobic conditions has been developed by Professor Shu Kobayashi and his research group at the University of Tokyo (Tokyo, www.chem.s.u-tokyo.ac.jp/users/synorg/index_e.html). The catalyst — nano particles (2.4-nm dia.) of gold and…
Optical cavity furnace can boost solar cell efficiency
Using an array of lamps inside a highly reflective chamber, the optical cavity furnace (OCF) takes advantage of photonics effects to help manufacture solar photovoltaic cells with higher efficiency than those made by conventional rapid-thermal-processing (RTP) methods. In addition, the…
First working FDI prototype
Last month at the Namur Annual General Meeting in Bad Neuenbahr, Germany, the first working prototype of FDI (field device integration) was demonstrated. FDI device packages were used to integrate Foundation Fieldbus, HART and Profibus field devices of various manufacturers…
