Scientists have found a method for recycling plastic package fuels
Despite attempts to reduce their use, and in some countries, these attempts have been made through various prohibitions and even fines, millions of plastic bags annually fill landfills pollute the seas and oceans. Fortunately, while all is not lost. Hope for a solution to this problem is not only that the plastic bags are considered by scientists in some countries as a potentially rich source for the production of carbon fabric and carbon nanotubes, but also in the fact that such products can be used for the production of various kinds of fuel consumption.
The scientific staff of Illinois Center for Development of environmentally sound technologies (ISTC) at the University of Illinois decided to apply the method of pyrolysis process hot (dry) processing of plastic bags, carried out in an oxygen-free sealed chamber. Although this method was originally used for a team of researchers reverse processing of plastic bags in crude oil (from which the actual packages and produced), scientists from Illinois were able to step forward and come up with the process of production of various kinds of fuel from the back of crude oil processed.
From the resulting raw researchers were able to create natural gas, kerosene, petrol, paraffin and lubricants, such as engine oil and hydraulic machines. In addition, they were able to produce diesel, which can be mixed with diesel or low sulfur biodiesel. The product obtained according to the scientists pass all quality standards to this kind of consumption in the United States .
“Obtained in the distillation process a mixture of two products, after the addition of an antioxidant, is fully consistent with the second type of diesel fuel standard adopted by the U.S. and meets all the requirements of diesel fuel, which is currently in use” – says Bradzhendra Kumar Sharma, head of the research project of the Illinois Center development of environmentally friendly technologies.
“We obtained a mixture of diesel has the same qualitative characteristics of energy equivalence, higher cetane number (flammability characteristics of diesel fuel, which determines the ignition delay period mixture) and better performance lubricity than diesel with low sulfur content.”
Upon mixing of 30 percent recycled plastic bags diesel with conventional diesel, scientists found no compatibility issues. The same result is shown mixing “plastic” diesel with biodiesel.
“It’s just incredible!” – Says Sharma.
“We can use” plastic “with conventional diesel without any problems and the need for technical changes to the engines.”
The big advantage of this technology, according to Sharma, is also a high performance processing.
“During the initial processing of oil in diesel, you get only about 50-55 percent of the original volume of the product. However, since plastic is itself manufactured from oil, the output you get almost 80 percent of the finished fuel. ”
More details of this study were published in the scientific journal Fuel Processing Technology.
