Abstract

Energy is an essential feature in our lives and vital to our well being. It is fortunate that the current oil price is low and there are surplus in the oil market. Bearing any major catastrophe the world will enjoy this phenomenon for guite sometime. The need to conserve energy has been put back and actions are taken to promote industrialisation further especially in the stiff demanding and competitive world. However there is still to need to study and aware of the potential of energy supply be it renewable type. Apart from this the environmental issue arising from the intensive utilisation of fossil fuels has become a serious concern throughout the world. As a result engineers scientists and technolgists are searching for new alternative and promising sources of energy. Rubber is one of the potential sources. From the elemental compisition and thermal characteristics of rubber it appeared that the rubber could be used for the production of alternative fuel via fixed-bed pyrolysis reactor sytem. Pyrolysis may be described as the thermal degradation of materials in complete absence or inadequate presence of oxygen. Recently pyrolysis is meant for dominant liquid production. The system is made from stainless steel. The system consists of gas pre-heater pyrolytic reactor liquid condenser and liquid collectors. The pyrolytic reactor is a 30 cm high and 5 cm diameter. The volume of the reactor is 520 cm superscript 3. The reactor was heated externally by cylindrical electric ring heater.
