Abstract

The demand of fuel continues to increase throughout the world. Over 81 million barrels of liquid fuel are consumed everyday worldwide for transportation vehicle; excluding the amount needed to produce plastics for daily use. Most of the transportation fuel is produced from crude oil, and this non renewable resource is declining day by day. With this decline in mind, the politicians and scientific community should emphasize more research to preserve this natural resource. Worldwide researchers are working to find out suitable environment friendly sustainable alternate source of liquid fuel. Now day’s plastic use are increasing constantly because plastics are light weight, durable and easy to use. After the short use, plastics become waste and create lots of problem for the environment. Plastic is not a biodegradable substance, and due this nature it remain in landfill for very long time; polluting the environment and its inhabitants. An established method has been studied and successfully demonstrates which converts majority of the waste plastic into liquid hydrocarbon fuel and can be used to power internal combustion engines. This new conversion process is an environment friendly and cost effective process that helps to preserve the environment while protecting our valuable natural resources.

Abstract

Experiments of combination waste plastics such as High Density Polyethylene (HDPE), Low Density Polyethylene (LDPE), Polypropylene (PP) and Polyvinyl Chloride (PVC) were carried out in a steel reactor. The thermal cracking process was carried out in temperature range of 150 ºC to 400 ºC. The principle process products are gaseous and liquid hydrocarbon fractions similar to refinery cracking products. The solid carbon residue of around 8 to 9 % of the total raw materials are similar to coal cokes and contains higher mineral contents than the other two products. Upon further analysis using gas chromatography and Mass spectrometer (GC/MS) and furrier transform infrared spectroscopy (FT-IR) of the liquid hydrocarbon fraction showed similar chemical properties to commercial gasoline and diesel products. The similarity was in the distribution of carbon chains and alkane groups. Analysis using differential scanning calorimeter (DSC) showed the calorific value is comparable as well. The thermal degradation process was shown to be efficient because it was able to convert PVC, which contains 56% chlorine to hydrocarbon products. Specific analysis was done for the identification of chlorine in the liquid hydrocarbon products, and results have shown that the liquid hydrocarbon products contained lower chlorine content than standard chlorine level allowed by EPA. Further research is being conducted on capturing and categorizing the gaseous component and the results will be submitted on the subsequent scientific papers.
