This photocatalyst works with visible light
A photocatalyst that uses visible light to deodorize and disinfect air has been developed by Hiroshi Taoda at the Materials Research Institute for Sustainable Development, National Institute of Advanced Industrial Science and Technology, Chubu, Nagoya, (AIST; Chubu, Nagoya, Japan; www.aist.go.jp).…
A gypsum-free, energy-saving route to lactic acid
Uhde GmbH (Dortmund, Germany; www.uhde.biz) is developing a new process for producing lactic acid (LA) — a monomer for making the biodegradable plastic polylactic acid (PLA) — that does not require a distillation step. As a result, savings in steam…
Making solar panels even greener
Last month, Malibu GmbH & Co, KG (Bielefeld, Germany; www.malibu-solar.de) started up a thin-film photovoltaic-module fabrication facility that is claimed to be the world’s first to eliminate the use of nitrogen trifluoride (NF3) — a greenhouse gas with a significant…
The missing piece for wireless process control
Last month, Honeywell Process Solutions (HPS; Phoenix, Ariz.; www.honeywell.com/ps) unveiled the process industry’s first redundant wireless system gateway (WSG), connecting the last major gap in the path to wireless process control. WSGs manage data between wireless field instrumentation and a…
New catalyst boosts liquid-fuel yield from heavy hydrocarbons
A new zeolite catalyst that increases yields of light cycle oil (LCO) from high molecular weight “bottoms” hydrocarbons in petroleum fluid catalytic cracking (FCC) units was commercialized last month by Grace-Davison, an operating segment of W.R. Grace & Co. (Columbia,…
A direct coal-liquefaction process goes commercial…
The world’s first commercial plant to produce liquid fuels by direct coal liquefaction is now being started up in Majata, Inner Mongolia, by Shenhua Group (Beijing). Designed to produce 25,000 bbl/d of syncrude from 4,300 metric tons per day (m.t./d)…
Add CaC2 to improve the efficiency of steelmaking furnaces
An innovation that improves the steelmaking efficiency of an electric arc furnace (EAF) by adding calcium carbide to the process has been developed by NuFlux, LLC (Warren, Ohio), a producer of steelmaking fluxes, and Carbide Industries LLC (Louisville, Ky.; www.carbidellc.com),…
A one-step process for extracting oil from algae…
Algae offer a ubiquitous, renewable source of oil for fuels and various chemical products ( CE, September 2008, pp. 22–25), but the extraction of oil from the algae cells is an energy-intensive process that involves dewatering and drying the biomass,…
A shocking way to compress CO2
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…
Upgrading natural gas
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…
