Through smaller scale modular reactors, engineers are reimagining how acrylonitrile (ACN) is made for industrial applications. ACN is a highly prevalent component of modern manufacturing, found in everything from the acrylics in car parts and textiles to the carbon fibers in sporting equipment.
Traditionally producing ACN requires large scale continuous energy intensive processes. But now, engineers from the University of Virginia and the University of Houston have demonstrated that by pausing production to "inhale" fresh oxygen, a chemical catalyst can more efficiently produce ACN.
The process, called "forced dynamic operation" or FDO by the researchers, opens the door for smaller and more versatile production facilities that can adapt to fluctuating demand. Their research is published in the journal Applied Catalysis A: General.
"FDO is essentially like giving the catalyst a breather, letting it work harder and more effectively in each cycle," said Zhuoran Gan, a Ph.D. candidate in the Department of Chemical Engineering at UVA. By letting the catalyst "rest" it regains the strength required for the next production cycle. In their work the team noted a 30% increase in ACN production when compared to traditional production techniques.
Given ACNs widespread use, the findings of the study could be transformative for several industries. Given the efficiency of the system, smaller less capital-intensive plants could be used to meet ACN growth demand while working closer with end-users allowing for more adaptable production.
