An attractive catalyst for making biodiesel fuels

It has been known for a long time that sulfonated active-carbon acid can catalyze both esterification and transesterification to produce biodiesel fuels from oils with high acid value without pretreatment. However, the separation of such catalysts requires filtration or centrifugation,…

Selective removal of micropollutants

Micropollutants, such as antibiotics and flame retardants, can pose a health threat to animals and humans, even in tiny concentrations. Current methods to remove micropollutants from the environment include adsorption onto powdered activated carbon, which is then separated from the…

This wastewater-treatment process also captures carbon dioxide

Researchers from the University of Colorado Boulder (Boulder, Colo.; www.colorado.edu) have developed a technology that combines wastewater treatment and carbon capture, resulting in a carbon-negative process that actually produces energy. The technology — called microbial electrolytic carbon capture (MECC) —…

A sound way to degas aluminum melts

During casting of aluminum alloys, degassing is required to remove hydrogen from the molten metal in order to prevent porosity in the solid metal that deteriorates its properties and performance. Currently, the so-called argon rotary degassing is used, where a…
