    The highly diversified field of industrial electrochemistry includes processes to synthesize organic and inorganic compounds, the conversion and storage of energy, galvanic deposition of metals and alloys. Electrochemistry also plays a lead role in corrosion protection, sensor devices, and other kinds of technology where charge transfer takes place at an electrified interface. Today, research...

    A detailed follow up of the cations present in the wastewater of the Monsanto Europe site in Antwerp, Belgium, has led to an increased understanding of changing wastewater treatment plant performance. The chemical process industries' (CPI) other wastewater treatment plants that handle continuously changing mixtures of different manufacturing plant effluents should also consider routine...

A paper-thin battery, with an electrode made from a redox-active organic polymer film (200 nm thick), has been designed by researchers at Waseda University (Tokyo; edlinks.che.com/6895-547). The polymer has nitroxide-radical groups that act as charge carriers. According to professor Hiroyuki Nishide, this “organic radical" battery presents several advantages over alternative, organic-based...

The cost of producing ethanol promises to be reduced by 50% through a process being developed by TNO (Zeist, Netherlands; edlinks.che.com/6894-536). The reason for the dramatic cut is that ligno-cellulosic material is hydrolyzed in a single step, using concentrated sulfuric acid. In contrast, conventional hydrolysis is a two-step process in which...

Demonstration plants to test six processes for producing ethanol from non-food-based biomass will be built with support from the U.S. DOE (edlinks.che.com/6894-543). Between them, the plants will produce more than 130 million gal/yr of ethanol from cellulosic feeds, including agricultural waste and perennial grasses. DOE's goal is to make cellulosic ethanol cost-competitive...

For the first time, it is possible to gain a detailed quantitative insight into the internal operation of multitubular reactors — complicated units that can be notoriously difficult to design because they involve complex catalytic reactions, a large number (often 2,0000 or more) of tubes, and closely coupled, shell-side heat transfer and hydrodynamics, says Mark Matzopoulos, marketing director at...
