Two stage pyrolysis–catalysis of used tyres was undertaken to upgrade the derived oil to a highly aromatic oil suitable to be used as a chemical feedstock rather than a liquid fuel. The tyres were pyrolysed in a fixed bed reactor and the evolved pyrolysis gases were passed through a secondary fixed bed reactor containing zeolite catalyst. The pyrolysis reactor was maintained at 500 °C and the influence of catalyst temperature between 430 and 600 °C on the yield and composition of the derived oils was examined......

Dear Sir,
I have read your articles ,its an eye opener for me.At present I am Pyrolysing 24 tons/day of waste tyre.Can U suggest me a CATALYST TO REDUCE THE PYROLYSIS TIME ,since I use a batch process 2.5 tons/batch, it takes 2 hrs /batch
