Gasoline from plastic packs

22.01.2007
A litre of gasoline can be obtained from a kilogram of old plastic sachets by appying a technology being developed by the specialists of the D.I. Mendeleev Russian Chemical-Engineering University.

This is one of unique examples how the scientists can use a material initially made of petroleum to get if not oil per se again but the product of petroleum refining - engine fuel.

“The idea of carbonic waste processing into carbohydrates is certainly no new news, says project manager Valery Shvets, Doctor of Chemistry, Professor. For example, two plants – a pilot one and an industrial-scale plant - have recently started operating in the US to process turkey factory wastes, mainly skin, feather and grease, into engine fuel. We, for our part, decided to focus our efforts on obtaining gasoline mainly from man-caused carbonic wastes – such as polyethylene, polypropylene, polystyrene and polyethylene terephthalate wastes. And we have achieved a lot of progress in this direction.”

The technology suggested by V.F. Shvets and his colleagues is based on catalytic thermal treatment of polymeric materials. Its basic stages are as follows. First, the wastes should be grinded (it is not necessary to wash them) and melted down. Them they should be mixed with the catalyst powder and exposed to thermal destruction, simply speaking –kept for some time in the reactor at a definite temperature and pressure.

The catalyst composition is not discussed by the researchers in public press – it is being patented now. It is only known that these are grinded wastes of a single production. Further, the liquid hydrocarbon fraction, which is practically gasoline, is topped and collected from the obtained mass. The authors suggest that gaseous decomposition products should be used as fuel: partly in the same production to ensure the required treatment process temperature, and the remainder – in any other process where fuel gases are needed.

The plant’s working model, or more precisely – a prototype model, is installed on the laboratory desk and functions duly. The plant allows to produce a liter of gasoline and a little fuel gas from a kilogram of polyethylene garbage (the petrol fraction content in the products of treatment reaches 90 percent). The waste represents black viscous substance resembling tar, saturated by the catalyst powder. There remains about a table-spoon amount of it per liter of gasoline. In principle, this product can also be used or burned down – then catalyst can be returned into the process.

Now the researchers continue the work in several directions at once. On the one hand, the reactor for the industry should be large, so scaling is to be performed, however, the authors will not be able to cope with this task independently – they will need to work jointly with production workers. On the other hand, the researchers are striving to make the process continuous, and they have made a lot of progress in this direction. And finally, one of the tasks is to develop a similar technology for processing animal and phytogenic wastes - meat-processing and poultry factory wastes. The US researchers have patented their technology and of course did not reveal the know-how. But the Russian chemists are sure: anything devised and made by one person can be invented by another person and even in a better way. Judging by the results already achieved, this is not beyond their powers.

Im Focus: Fizzy soda water could be key to clean manufacture of flat wonder material: Graphene

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.

As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...

Im Focus: Exotic quantum states made from light: Physicists create optical “wells” for a super-photon

Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.

Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...

Im Focus: Circular RNA linked to brain function

For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.

While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...

Im Focus: RAVAN CubeSat measures Earth's outgoing energy

An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.

The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...

Im Focus: Scientists shine new light on the “other high temperature superconductor”

A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.

Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
