as coal and biomass. Southern Research will provide WRI with renewable acrylonitrile. Other members of the WRI project include Ramaco Carbon, which is working on ways to use carbon from coal as a carbon fibre precursor, and also Oak Ridge National Laboratory (ORNL), which has a process to make carbon fibre from low-cost acrylic fibre. A manufacturing technique called plasma

product has been validated by carbon fibre producer Cytec (now part of Solvay), meeting its purity specifications. A pilot plant is planned for completion by early 2019, and SR anticipates that, if successful, the technology could be commercial in 2021-22. Amit Goyal, Senior Manager and Principal Investigator on the technology, says SR has several ongoing discussions with strategic partners that have shown interest. “The Southern Research process has the promise
of changing the economics and environmental footprint of this important specialty chemical,” says Bill Grieco, Vice President of SR’s E&E division. “Making that process more robust and agnostic to biomass sugar feedstock is another important step toward commercialization of the technology.” The Western Research Institute (WRI) recently obtained funding from the US Department of Energy to develop low cost carbon fibre compo- nents using various resources as the feedstock, such
oxidation, which is based on work begun at ORNL in collaboration with RMX Technologies back in 2004 and is said to produce carbon fibre three times faster than conventional routes, using a quarter of the energy and at a total manufacturing cost around 20% lower, could soon be in commercial use. Three years ago, a research team built a continu- ously operating plasma oxidation line that runs multiple tows (or spools) of carbon fibre with a capacity of one tonne/yr. The line has operated for hundreds of hours without major failures. Two years ago, RMX Technologies formed a subsidiary, 4M Industrial Oxidation – now an independent company – to commercialise plasma oxidation. Earlier this year, 4M signed a letter of intent with industrial oven make CA Litzler to jointly commercialise the world’s first commercial scale oven for carbon fibre production. Matt Litzler, President of CA Litzler, said in May that the com- pany had received requests for three quotes. Meanwhile, Zoltek, which supplies some of the most price-competitive commercial carbon fibres available today, said earlier this year that it would double the capacity of its Mexico facility this year to more than 10,000 tonnes/yr, taking its global capacity to more than 20,000 tonnes/yr (it has a second facility in Hungary).
