Conversion of plastic packaging to BTX and olefins is demonstrated

By Scott Jenkins |

Anellotech (Pearl River, N.Y.; www.anellotech.com) recently announced a successful laboratory demonstration of a process to convert mixed plastic waste into a host of useful starting materials for new plastics. The process (diagram), known as Plas-T-Cat, would take place in a fluidized-bed reactor, and is envisioned to convert plastics, such as thin-film snack-bag packaging, into olefins (ethylene and propylene), BTX (benzene, toluene and xylenes) and other products. With heat to effect polymer chain cracking, and ZSM-5 zeolite catalysts to control the reforming reactions from the pyrolysis gas, Anellotech’s proprietary process has the potential to, within the same unit, convert polyolefins alone or as part of composite packaging. “The catalytic pyrolysis has the potential to generate commercially relevant yields of olefins, while reducing the mixture of waxes that you would see in a non-catalytic process,” explains David Sudolsky, CEO of Anellotech. “Alternatively, we can adjust the operating conditions to obtain a higher proportion of BTX, along with lower-molecular-weight olefins, paraffins, C5 liquids and other compounds.” It is believed that the Anellotech process can deal with the unique set of contaminants observed…
