Rex,
And where is this plant situated?

As the reactions begin to occur, the catalyst cracks the long chains and systematically deoxygenates the liquid by dehydration (H2O), decarboxylation (CO2) and decarbonalyation (CO) leaving a low oxygen content oil as the liquid product. The benefit of the low oxygen is that, after fractionation, this oil can be added to mineral diesel and kerosene. Alternatively, if supplied to a refinery, it can be added to the feed going to the hydrotreater where deoxygenation is completed. This puts it equivalent to mineral based fuels.

> Empyro BV announces that the construction of its pyrolysis oil production plant has started at the AkzoNobel site in Hengelo (The Netherlands). By the end of this year construction will have been completed. The production capacity will then be gradually increased to its maximum of over 20 million litres of pyrolysis oil per year. This amount of renewable oil will replace 12 million cubic meters of natural gas, the equivalent annual consumption of 8,000 Dutch households, which saves up to 20,000 tonnes of CO2 emissions per year. Additionally, the project creates approximately 100 person-years of work in Overijssel.
