A more efficient way to convert CO2 into chemicals via MER
Microbial electrochemical reduction (MER) of CO2 into value-added chemicals is a potential way to curb greenhouse gas (GHG) emissions. MER uses chemolithoautotrophs, which are microbes found in the deep sea, in caves and in hydrothermal vents. These bacteria get their…
Nano-engineered cellulose prevents scaling
Efforts to find more environmentally friendly anti-scalant approaches have yielded a new form of functionalized nanocellulose that can prevent the nucleation and growth of calcium carbonate, the most common component of industrial scale. Based on the biopolymer cellulose, the anti-scaling…
Making jet fuel from wood
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…
Transforming plastic waste into useful aerogels
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…
Recovering rare-earth elements from coal byproducts
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 catalyst that mimics enzymes
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,…
New process taps into lithium-bearing micas
The increased demand for lithium in recent years — driven mainly by battery manufacturing — has broadened the scope of lithium-processing technologies. Typically, lithium is mined from spodumene ore or sourced from brine deposits, but a new process enables lithium’s…
Advanced facility accelerates commercial development of nanoscale materials
Flame-spray pyrolysis (FSP) is a type of aerosol synthesis in which solid particles condense from the vapor phase after the combustion of droplets of solution. FSP has been used to produce industrially important nanoscale solids, such as fumed silica, alloy…
Chementator Briefs
Commercial Debut The world’s first commercial plant based on the patented PLAneo technology of thyssenkrupp Industrial Solutions AG (Essen, Germany; www.thyssenkrupp-industrial-solutions.com) recently started production in Changchun, China. Operated by the Jilin COFCO Biomaterial Corp., the new plant produces all standard…
A solar-powered electrolysis process extracts lithium from seawater
Today, all commercial lithium is sourced from ores or brines on land, where the total lithium reserves amount to 14 million tons. In contrast, the oceans contain 230 billion tons of lithium, although the lithium concentration in seawater is very…
