Compressing carbon dioxide captured from power plants to 1,500–2,200 psia for pipeline transmission or underground injection is a challenge that requires eight stages or more, using conventional compressors. A compressor that promises to do the job in two stages, for…
A process that produces hydrogen-enriched natural gas, with carbon black as a byproduct, is being developed by Atlantic Hydrogen Inc. (Fredericton NB, Canada; www.atlantichydrogen.com). The company has piloted the process at a scale of 25 m3/h of natural gas…
Hajime Kawanami and colleagues at the AIST Tohoku Collaboration Center, Research Center for Compact Chemical Process, National Institute of Advanced Industrial Science and Technology (AIST; Sendai, Japan; www.aist.go.jp) have developed a continuous, one-step process for synthesizing hydroxymethylfurfural (HMF), a biologically…
Hiroshi Abe and colleagues at Biochemical Group of Research Institute for Innovation in Sustainable Chemistry, National Institute of Advanced Industrial Science and Technology (Tsukuba, Japan; www.aist.go.jp) have discovered a strain of acetic-acid bacteria (which normally oxidize ethanol into acetic acid)…
As it is with all chemical processors, the current economic climate is forcing batch processors to produce more saleable product at a better profit margin from the same assets. Increasing flexibility, reliability and visibility while decreasing batch cycle times via…
Cast parts, such as engine blocks, are typically made by pouring molten metal into so-called cores — sand-based molds that have internal passages for the component to be cast. Such casting cores are typically made by reacting sand with organic…
SynGest, Inc. (San Francisco, Calif.; www.syngest.com) plans to commercialize a process for the production of ammonia from biomass by the fall of 2011. The first plant, to be located in Menlo, Iowa, will convert 150,000 ton/yr of corncobs into 50,000…
A new procedure for making uniform, metallic nanoparticles has been developed by the research group of Kousuke Mori, an associate professor at Osaka University (www.mat.eng.osaka-u.ac.jp), with support from New Energy and Industrial Technology Development Organization (NEDO; Kawasaki, both Japan). The…
The exceptional properties of carbon nanotubes (CNTs), such as high tensile strength and high thermal and electrical conductivities, have suggested a number of applications, including lightweight materials for ballistics protection, actuators for muscles or artificial muscles, filaments for light sources,…
Salts of alkaline-earth metals have been shown to catalyze reactions for the selective formation of carbon-carbon bonds, by chemistry professor Shu Kobayashi and colleagues at the University of Tokyo (www.chem.s.u-tokyo.ac.jp). The research, supported by the Japan Science and Technology Agency…
