Catalytic pyrolysis of automobile shredder residue

Recycling of auto shredder residue

“…This approach was developed at Argon national laboratory in the USA [23]. A synthetic ASR made up from pure materials was pyrolised in a ceramic tube reactor inserted into the 30-cm heating zone of an electric furnace.…”

“…In the presence of Fe 3 O 4 and oxidation of carbon by the metal oxide, the reaction generates about 18% of CO 2 . The role of catalysis is to lower the decomposition temperature by lowering the activation energy [23].…”

Recovery of fuels and chemicals through catalytic pyrolysis of plastic wastes

“…Along with many other researchers, we have chosen to study this possibility. For example, Kaminsky has developed a fluidized-bed process to pilot scale [5], h u m a n i d i s has shown that wood can scavenge HCI and form CH,CI when pyrolyzed with PVC [6], and Zang has shown that BaO and other bases can dramatically increase liquids when used as solid catalyst in plastics pyrolysis [7].…”

End-of-life vehicle recycling : state of the art of resource recovery from shredder residue.

“…Specifically investigated were controlled thermal extrusion to produce a synthetic particulate coal (Jones 1994) and catalytic pyrolysis to produce gaseous and liquid fuels (Arzoumanidis et al 1995;Brockmeier and McIntosh 1994). Again, although these processes are technically feasible, they are generally not cost-effective given the economic environment in North America (i.e., low landfill costs and low oil/energy costs relative to those costs in either Europe or Japan -countries in which this type of technology may be more costeffective) (Arzoumanidis et al 1995;Brockmeier and McIntosh 1994;Jones 1994). …”
