Today, olefins are mainly made either by naphtha cracking or by the catalytic conversion of dimethyl ether (DME), which is in-situ made from synthesis-gas- (syngas) derived methanol (methanol-to-olefin processes). Both naphtha cracking and syngas production (from steam-methane reforming; SMR) require…
Researchers from Case Western Reserve University (CWR; Cleveland, Ohio; www.case.edu) have shown that a hybrid electrolytic system using a gaseous plasma electrode can produce ammonia from water and nitrogen at ambient temperature and pressure — without any catalytic material surface.…
The quest to generate chemicals and fuels from exhaust or atmospheric carbon dioxide got a boost from a series of recent studies by researchers at Lawrence Berkeley National Laboratory (LBL; Berkeley, Calif.; www.lbl.gov), in which the scientists proved the viability…
Professor Kazuaki Ishigreo and colleagues at Nagoya University (Nagoya, Japan; http://en.nagoya-u.ac.jp) have shown that a chiral, supramolecular, U-shaped, boron Lewis acid catalyst (diagram) promotes the unprecedented multi-selective Diels–Alder reaction of propargyl aldehyde with cyclic dienes. The Diels–Alder reaction, which is…
A process that increases the water-recovery from reverse osmosis (RO) while producing a salt byproduct is being developed by Hyrec (Urla/Izmir, Turkey; www.hyrec.co). The process, which uses osmotically assisted RO (OARO), could be especially beneficial in coal-to-chemicals (CTC) plants in…
New PDH capability A new catalyst for propane dehydrogenation (PDH) that does not include precious metals has been developed by KBR Inc. (Houston, Tex.; www.kbr.com). The new catalyst is incorporated into KBR’s new PDH technology, known as K-PRO, which was…
Last month, construction began on a demonstration facility that integrates high-performance entrained-flow gasification technology and Fischer-Tropsch (F-T) synthesis for making jet fuel from woody biomass. The demonstration project is being carried out by a Japanese consortium, led by Mitsubishi Hitachi…
Plastic-bottle waste is toxic and non-biodegradable, and has become a major environmental issue. It often ends up in the oceans, affecting marine life, or in landfills, contaminating groundwater and affecting land use. Now a team led by professors Nhan Phan-Thien…
A team from the University of Kentucky (Lexington, Ky.; www.uky.edu) and Virginia Polytechnic Institute (Blacksburg, Va.; www.vt.edu) has set up a novel pilot plant to recover rare-earth elements (REEs) from coal-based sources, aiming to produce high-grade REE concentrates from coal-based…
A research team from the University of New South Wales (Sydney, Australia; www.unsw.edu.au) and Ruhr-Universität Bochum (Bochum, Germany; www.ruhr-universität-bochum.de) has succeeded in transferring structural characteristics of natural enzymes to metallic nanoparticles, achieving high catalytic activity. In the case of enzymes,…
