Automobile catalytic converters contain cerium-based co-catalysts to enhance the overall effectiveness of the converter by absorbing and releasing oxygen to convert CO into CO2. Existing emission control systems typically use CeO2-based materials, such as solid solutions of ceria and zirconia,…
A convenient route for the fabrication of a bio-mimetic, coral-like nanoporous γ-Al2O3 with a higher capacity to adsorb Hg(II) in aqueous solution than those of commercial Al2O3, has been reported by a research group from Anhui Jianzhu University (Hefei City,…
A recently announced process based on a novel solid-acid catalyst is effective at producing high-quality alkylate from a variety of feedstocks, including methanol. Technology developer Exelus Inc. (Fairfield, N.J.; www.exelusinc.com) says its technology converts methanol and mixed-butanes to high-octane alkylate.…
Copper and cadmium exist naturally in the environment, but human activity can increase their concentrations to a point where they become a health hazard. Conventional wastewater treatment to remove those metals includes chemical precipitation, coagulation, flocculation, ion exchange, membrane filtration,…
PET recycling Polyethylene terephthalate (PET) can be quickly depolymerized into virgin monomers using a patented process that was developed, and is being scaled up by Ioniqa Technologies BV (Eindhoven, the Netherlands; www.ioniqa.com). The company recently finalized a multi-million-euro funding round…
Increased use of ethane from shale deposits as a feedstock for ethylene production has focused attention on the growing need for on-purpose production of butadiene, which has traditionally been produced primarily as a byproduct of conventional ethylene production from naphtha.…
Scientists from Yonsei University (Seoul, South Korea; www.yonsei.ac.kr) led by Prof Eunkyoung Kim, have developed a hybrid solar cell to enhance the photo-conversion efficiency of a solar cell with a thermoelectric device operated by photothermally generated heat. The efficiency was…
As world leaders agree on the need to reduce greenhouse gas (GHG) emissions, major milestones and new technologies point toward potential solutions Last month, delegates from 195 countries converged on Paris, France for the 21st Conference of the Parties (COP21;…
A dry adhesive technology inspired by the microscopic hairs on gecko’s feet is said to be the first of its kind to be commercialized. Known as Setex, the technology was developed by nanoGriptech Inc. (Pittsburgh, Pa.; www.nanogriptech.com), a company spun…
Modular construction provides many benefits, but the decision to go modular should be thoroughly investigated Modular construction, which includes projects from small- and large-scale process systems to pilot plants to entire modular facilities, is a growing trend in the chemical…
