Description

Butyl inner tubes are used as inner tubes and inner liners in tubeless tyres. After some time it is disposed as waste because its efficiency has become reduced. Proper disposal or beneficiation of waste inner butyl tubes are of the great concern, both environmentally and for resources conservation. An environmentally friendly method for conversion of used isobutyl isoprene rubber inner butyl tube into useful products has been investigated. The method is based on catalytic cracking using batch type reactor. Optimum conditions like temperature, catalyst weight and reaction time were optimized for maximum conversion into oil for a variety of catalysts.
