Improving extraction yields of Ni and Co from laterite
Low-grade nickel (less than 1.5 wt.%) laterite ores represent about 70% of global reserves but account for only 40% of nickel production. Increasing demand for nickel in recent years has created the need to process such ores. Atmospheric acid leaching…
First commercial process for K2SO4 from polyhalite completes pilot
Pilot plant operation has been completed for a process that produces the fertilizer potassium sulfate from the mineral polyhalite, a hydrated sulfate of potassium, magnesium and calcium. The process, developed by Intercontinental Potash Corp. (ICP; Golden, Colo.; www.icpotash.com), resurrects a…
An efficient way to make fermentable sugars from fibrous waste
The National Food Research Institute (NFRI) of the National Agriculture and Food Research Organization (NARO; Tsukuba City, Japan; www.naro.affrc.go.jp) has developed an enzymatic pretreatment process for producing highly concentrated sugar solution from fibrous materials containing rice straw and starch. The…
This gasification process turns waste into syngas
Construction of a large-scale waste-to-energy plant will start in the middle of next year in Port Hedland, Western Australia, and operation is scheduled to commence in the second quarter of 2015. The plant will be built by the New Energy…
A new gas-engine cogeneration system
Last month, Mitsubishi Heavy Industries, Ltd. (MHI; www.mhi.co.jp) and Tokyo Gas Co. (both Tokyo, Japan; www.tokyo-gas.co.jop) began marketing a jointly developed 1,000-kW gas-engine cogeneration system. Based on the conventional 930-kW system, the new systems engine operates at a reduced speed…
A new proppant
Last month, Carbo Ceramics Inc. (Houston; www.carboceramics.com) introduced KryptoSphere, an ultra-conductive, high-strength proppant technology designed to maximize and sustain hydrocarbon flow at high closure stresses for the life of the well. Developed in response to a request from a major…
Dandelion rubber
Last month saw the start of a five-year joint research project to extract rubber from dandelion plants to make tires. In collaboration with Continental AG (Hannover, Germany; www.continental-tires.com), the Fraunhofer Institute for Molecular Biology and Applied Ecology (IME; Aachen, Germany;…
Transporting more H2 gas
The Linde Group (Munich, Germany; www.linde.com) has developed a new storage technology that will enable a much more efficient transport of larger amounts of hydrogen. The new solution works at a higher pressure of 500 bars (7,250 psi) and uses…
Plasma-modified CNTs show promise for water purification
An international team of researchers claims to have developed carbon nanotube (CNT) membranes with an ultrahigh specific-adsorption capacity for salt that is two orders of magnitude higher than that found in current activated-carbon-based water-treatment systems. The team includes researchers from…
KIT makes ‘gasoline’ for the first time
Last month, the synthesis stage of the bioliq (biomass to liquid Karlsruhe) pilot plant produced gasoline for the first time at the Karlsruhe Institute of Technology (KIT; Germany; www.kit.edu). The achievement is a milestone in that all stages of the…
