Concrete Admixture Advanced concrete mixes often demonstrate a higher viscosity due to their low water contents. Although having a high level of workability, the concrete often appears harsh, sticky and therefore difficult to pump and process. To overcome these challenges…
Researchers from Singapore’s Institute of Bioengineering and Nanotechnology (IBN; www.ibn.a-star.edu.sg) and Hydro-Quebec’s Research Institute (Montreal, Canada; www.hydro.qc.ca) have synthetized silicate-based “nanoboxes” that could greatly increase the energy capacity of lithium-ion batteries as compared to that of conventional phosphate-based cathodes. IBN’s…
Innovations and the utilization of byproducts are helping this sector to thrive in difficult times The pulp-and-paper industry has gone through difficult times. The rise of electronic media, competition from substitute materials and environmental concerns have caused thousands of mill…
IHI Corp. (IHI; Tokyo, www.ihi.co.jp) has commissioned its first prototype Twin IHI Gasifier (TIGAR) plant, which IHI designed and built at the Kujang Factory of PT Pupuk Indonesia Holding Co., Indonesia’s largest state-owned fertilizer company, 75 km southeast of Jakarta.…
Improvements in existing materials and the development of new ones are helping to meet the demands of challenging applications As the need for stronger, more durable and lighter-weight materials increases, the demand for high-performance plastics and polymers continues to grow.…
Two families of newly developed products from specialty chemical maker Solenis (Wilmington, Del.; www.solenis.com) — a portfolio of fermentation aids and scale inhibitors — have the potential to improve the production of bioethanol and related fermentation processes. Solenis fermentation aids…
Construction has begun on a commercial prototype of a low-boiling-point solvent-extraction process for recovering used catalyst powder and slurry oil from a recalcitrant sludge produced in the fluid catalytic cracking units (FCCUs) of petroleum refineries. The process allows refiners to…
Many chemical process industries (CPI) operations generate gaseous byproducts that are impure and have low energy densities. Ener-Core Power Inc. (Irvine, Calif.; www.ener-core.com) has introduced a technology to extract valuable energy and heat from gases that would otherwise be wasted…
Hydrocracking Later this year, Albemarle Corp. (Baton Rouge, La.; www.albemarle.com) says it will add a new catalyst to its STARS (super type II active reactive sites) catalysts portfolio. Together with its Hydroprocessing Alliance partner, UOP LLC (Des Plaines, Ill.; www.uop.com),…
A new process for partially devulcanizing and functionalizing micronized rubber powders (MRP) may allow the use of higher levels of the material than originally allowed in vehicle tires and other applications. Currently, MRP from end-of-life rubber is being used in…
