Peak oil signifies disaster for plastics producers — ethene, one of the raw materials used to make plastics, relies on abundant supplies of oil for production.
But Dutch researcher Tymen Tiemersma thinks he has a solution: a reactor that can produce ethene from natural gas.
Describe the procedure to synthesize the ester ethyl ethanoate (ethyl acetate), starting from ethene.? en Español
Gouw found that the concentrations of ethene and propene -- which both contribute to ozone formation -- dropped by 52 percent and 48 percent respectively between 2000 and 2006.
Tiemersma found an apparently very simple solution for one of the biggest problems in producing ethene from natural gas.
Each year the world produces about 130 million kilo of ethene, the most important raw material for plastics.
The process technologist merged the production of syngas with the production of ethene and developed a method for obtaining both substances efficiently from natural gas.
The production of ethene generates the heat needed for the production of syngas - which must take place at temperatures around 800 degrees Celsius - and the syngas absorbs the heat from the production of ethene, thus avoiding the need for this process to be cooled down.
Yet natural gas is not only used for the production of ethene.
If you want to produce plastics from natural gas then you first of all need to convert the natural gas into ethene.
