Abstract:

A mixture of waste rubber of tyre and Makarwal coal of Pakistan was converted into oil using microwave metal interaction pyrolysis. The reactions were carried out in reactor containing copper coil which supported in high temperature microwave-assisted pyrolysis. The high temperature is generated by the interaction of microwaves with copper coil, coal and the bake clay reactor. Copper is used as antenna for the microwaves and it is believed that this antenna may also catalyze the pyrolysis process and affect the nature of products. This faster method of liquefaction gives 12% aqueous liquid, 58% oily liquid, 3% benzene soluble tar, 2 % gases and 25% residues. The liquid products were collected using cold traps and the amount of gas was obtained by taking difference. The mixture of tarry and oily liquid product was analyzed using GC/MS and found that it contains aliphatic and aromatic compounds. It was investigated by the chemical tests that the gases contain hydrogen sulfide and acetylene in addition to other fuel gases. The range of products and product formation is also discussed in this communication
