SULFREE · Tyre Recycling Pyrolysis for producing oil with less than 0.2% sulphur content, low cost sulphur impregnated carbon for reducing mercury air emissions, with simultaneous elemental

SULFREE offers a complete, end-to-end process for ELT recycling, which breaks down tyres to valuable productsthat can be reused by the EU tyre industry; instead of merely recycling them either as tyre crumb or as fuel (i.e.tyres are burned for power production). The recovery of oil and sulphur reduces the dependence on importedproducts and lessens the effect of price volatility on tyre production whereas the sulphur-impregnatedactivated carbon (S-AC) will aid in reducing mercury emissions.The project will (a) develop a novel, platform technology implementing a specially designed Fixed Bed Reactorfor the hydrodesulphurisation of the pyrolysis vapour (combined oil and gas fraction), resulting in a gas rich inhydrogen sulphide (H2S) and oil with sulphur content less than 0.2%, (b) develop a monoethanolamine (MEA)stripper to capture H2S from the gas and optimize the Claus Process for recovering the sulphur (c) optimizemicrowave pyrolysis technology for breaking down end of life tyres and (d) optimize the technology foractivating the solid carbon black. The gas and heat produced during the process will be used for the energyrequirements of the process and for activating the solid carbon black. The major novelty of the process is thatthe fixed bed reactor, the MEA stripper and the Claus process will design and operate at a significantly smallerscale.
