High-pressure fermentation for optimizing CO2 utilization

Biological processes can be used for the conversion of greenhouse gases into added-value chemicals. With a new, unique high-pressure (up to 10 bars) fermenter, the Flemish Institute for Technology Research (VITO; Mol, Belgium; www.vito.be) is researching how these processes can…

Cost-efficient, on-purpose 1,5-PDO from bio-based starting material

Construction is underway on a demonstration plant for manufacturing 1,5-pentanediol (1,5-PDO) from bio-based furfural, a platform chemical that can be derived from plant-based hemicellulose sugars. The process under construction by the company Pyran Inc. (Madison, Wis.; www.pyranco.com) offers a lower-cost…

Fibrous catalyst support boosts yields and reduces coke buildup

A new fibrous catalyst-support material can enhance a wide range of industrial catalytic reactions, allowing higher yields and reduced coke buildup compared to pellet supports. Unifrax (Tonawanda, N.Y.; www.unifrax.com) leveraged its expertise in ceramic materials to develop the high-alumina fiber…

Low-energy hydrogenation without H2 gas

Hydrogenation is an important reaction in many sectors of the chemical process industries (CPI), but H2 gas is not only expensive, its use requires considerable safety measures to prevent explosions. Significant cost savings could be achieved if hydrogenations did not…

Chementator briefs

Toxicology testing The world’s first toxicology-testing strategy without animal testing has been approved by the Organization for Economic Co-operation and Development (OECD; Paris, France; www.oecd.org). The testing strategy consists of three so-called alternative methods. They can be used to predict…

Piloting a process that makes hydrogen and carbon from methane

Next year, construction will begin on an industrial-scale pilot plant to further develop a new process that decomposes methane into H2 and carbon. The process uses a thermo-catalytic decomposition (TCD) technology developed by Hycamite TCD Technologies Oy (Kokkola, Finland; www.hycamite.com).…

Technology Profile: Production of Nitrogen from Air

Nitrogen (N2) makes up 78% of ambient air (20.95% of air is oxygen). N2 is an inert (non-flammable) gas used in industrial plants to prevent undesirable chemical reactions from occurring. Nitrogen is the most common inert gas used in the…

Time and Length Scales of Mixing: The Macro Scale

Successfully scaling up a mixing process involves understanding several important timescale parameters that can impact chemical reactions and equipment performance Many industrial processes are defined by rates. For example, rates of mass and heat transfer, rates of reaction and rates…
