RECYCLED PLASTIC MATERIALS AS USEFUL PROD UCTS FOR REFINERIES

Raw material recycling is an important and necessary means of material reutilization of plastics. Processes and plants which are already ava ilable should be used. Visbreaking is a relatively inexpensive residue upgrading process. Therefore investigations in coprocessing of therma l pretreated plastics with vacuum residue - the conventional starting material - were performed in a laboratory vis-breaker. The consistency of the mixtures were estimated with instrumental analytical technique s. The mixtures were reacted under mild thermal cracking conditions. C onversion product distribution and product properties were measured. T he addition of pre-treated plastics in specific percentages does not l ead to any significant changes in the process and product parameters.
