  Reforming catalyst Haldor Topsøe A/S (Lyngby, Denmark; www.topsoe.com) has introduced a new alkali-promoted steam-reforming catalyst, dubbed RK-400. RK-400 is engineered to protect against unwanted carbon formation while achieving a higher level of catalytic activity than those previously seen in this class, says the company. RK-400 has a reservoir of potassium promoter integrated within the...

Industrial microbiology continues to hold the promise of producing an increasingly large array of commercially important chemicals because an ever-wider number of useful microbes is being developed and successfully deployed at commercially viable scales. Today, many of these bio-based chemicals are needed in quantities so large that existing fermentation technology is inadequate, and this is pushing the...

Iron ore is traditionally pelletized using the binding agent bentonite to facilitate transport and handling. A new additive for pelletizing iron ore significantly reduces the volume of binding agent required, while improving pellet strength and production output. Developed by Clariant AG (Muttenz, Switzerland; www.clariant.com), the pelletizing additive is a patented polymer-based binding agent that can...

Fermenting sugar is at the heart of many bio-based chemical and biofuel processes, but obtaining sugars from cellulosic biomass at low cost is an ongoing challenge. A new process using a reusable solid catalyst is capable of breaking down a wide range of waste biomass into fermentable sugars at costs lower than deriving sugar from corn or sugarcane. Midori Renewables (Cambridge, Mass....

When coal-derived synthesis gas (syngas) is converted to liquid fuel by the Fischer-Tropsch (F-T) process, the initial product is mostly straight-chain waxy paraffins that can be upgraded by hydroprocessing to obtain diesel fuel and naphtha, which are used for gasoline blending. Only about 16% of the F-T plant output falls directly into...

  Strength with stress Shear forces usually break bonds in polymer materials, but a research team at Duke University (Durham, N.C.; www.duke.edu) has demonstrated for the first time synthetic polymers capable of forming new bonds in the presence of shear forces that would normally break down polymer chains. Termed activated remodeling via mechanochemistry (ARM), the concept depends on a mechanically...
