Driven by consumer demand and regulatory pressure, paint and coating formulators, along with makers of chemical additives for those markets, have brought to the forefront products with improved environmental and health performance Modern paints and coatings are complex mixtures of…
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,…
Improved seals, gaskets and valve packings stand up to tougher process conditions Chemical processors expect more from their seals, gaskets and valve packings than ever before, as sealing components must meet tighter and stricter regulations regarding emissions, stand up to…
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…
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…
Alkylate — the main component in high-octane gasoline — is produced by catalytic reaction of C3–C5 olefins with isobutane in the presence of strong acid catalyst. Although there has been progress in the use of solid-acid catalysts (see, for example,…
