A process that produces renewable hydrogen from organic biowaste and reduces the economic and environmental burden of wastewater treatment is being developed by Chemergy, Inc. (Miami Fla.; www.chemergy.com). Introduced at last month’s AIChE Spring Meeting (April 22–26; Orlando, Fla.), Chemergy’s…
Petroleum refiners looking to upgrade low-octane naphtha have an additional option using a process that increases the higher-octane iso-paraffins and aromatic compounds at lower costs than currently available alternatives. Most refiners currently upgrade naphtha by hydrotreating followed by isomerization and…
A new fermentation-based technology aims to create leather materials from yeast rather than animal skin. Developed by Modern Meadow (Nutley, N.J.; www.modernmeadow.com), the process feeds sugar feedstock to yeast cells that have been engineered to create collagen. Some additional enzymes…
A remote-operated, screw-propelled (amphirol) machine equipped with a vacuum hose can remove solid catalyst material from reactors robotically, allowing plants to avoid subjecting personnel to enclosed work environments and inert atmospheres. Currently, catalyst changeout requires personnel to work inside process…
Hydrotreating is an important petroleum refining process in which sulfur and other contaminants are removed in the manufacture of transportation fuels. At the recent annual meeting of the American Fuel and Petrochemical Manufacturers (AFPM), Honeywell UOP (Des Plaines, Ill.; www.uop.com)…
A group of researchers from South Dakota School of Mines and Technology (SDSM&T; Rapid City; www.sdsmt.edu) has developed a modular technology known as the Gas Cube, which can convert a wide variety of liquid and solid waste into methane. Having…
Hydrogen sulfide occurs naturally in petroleum reservoirs, but must be removed from crude oil prior to transportation from drilling sites to storage tanks at petroleum refineries. H2S is corrosive to storage tanks, pipelines and railcars, and without proper treatment, can…
The global textile industry generates a great deal of waste, and many efforts are taking place to make textile processing more sustainable. PolyOne Corp. (Cleveland, Ohio; www.polyone.com) has introduced a new fiber-colorant technology for polyester that incorporates proprietary high-pressure metering…
A group of Japanese researchers have developed a photocatalytic panel reactor with large area (1 m2) that splits water into H2 and O2 using only natural sunlight. The NEDO (www.nedo.go.jp)-supported project — which includes partners Japan Technological Research Association of…
Polysiloxanes are the main component of important industrial materials, such silicones and organosilicones. In recent years, demand has grown for higher-performance and higher-functionality of organosilicon materials, which require techniques that precisely control the structure of these materials. Although there are…
