Folks,

On Friday and again on Monday (yesterday) we converted sawdust into a
hydrocarbon oil. 

Essentially what we are trying to do is "low temperature catalysis" (see
Ernst Bayer patent from the '80's which produced gas, "petrochemical oil"
and char) which involves slow (as opposed to fast pyrolysis) heat up of
biomass in the presence of a catalyst. 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.

While this is not gasification, it is an interesting progression of trying
to convert biomass into a renewable fuel, in this case liquid. Our next step
is to add two more upstream processing steps to improve the overall process.

Kind regards
Rex Zietsman

Tom Taylor and all

We Humans are word manipulators, mostly to our benefit. 

But "pyrolysis oil" is a dangerous misnomer! Hydrocarbon oils have been
fully reduced by geologic processes and store maximum energy In a Minimum
volume. 

Oil can be represented as chains of CH2 of varying length. 

Carbohydrates, CH2O,(sugars, C6H12O6 and their polymers, starch and
cellulose, C6H10,O5) are already 1/3 oxidized, and as such, are much more
reactive for the purposes of life. 

So further oxidation to the witches brew of pyrolsis "oils" is the wrong
direction. Don't be misled by the name!

Does anyone know how they address the problems of pyrolysis oil such as it's
acidic nature, tends to harden by auto oxidation over time, and other issues
that the US DOE has spent significant amounts of money on and no one that I
am aware of including folks trying fast pyrolysis have overcome? 
	In the late 60's or early 70's Occidental Chemical tried a 200
ton/day fast pyrolysis plant in the San Diego area that ran for 8 hours
before they scrapped it. This has been going on for a long time.

has allready been build in Norway, but due to the fact that the oil
producing government of Norway (or Statoil), was not ready to give them a
start up tax reduction for their finished products, its is not in operation.

A pilot plant in a smaler scale, has been running for some time now, funded
by EU.

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.
