1. Is my feedstock suitable for the pyrolysis process?
Most biomass can be pyrolysed with BTG-BTL’s technology. BTG has tested over 45 different types of biomass and less then 5% was not that succesfull. Nevertheless BTG-BTL always needs to test the feedstock on their pilot plant to be able to determine the specific yield, biomass behaviour and other specific characteristics.
2. What are the optimal feedstock dimensions?
|Size:||3 mm(*Y *Z)|
A dryer is integrated into the BTG-BTL system that can dry the biomass from about 50% to the required moisture content of <10%, without using fossil fuels. A sizer can also be part of the scope. BTG-BTL will be involved in the whole chain that is required to make the pyrolysis installation successfull and therefore BTG-BTL will assist you with all necessary pretreatment steps.
3. Are the Kyoto Protocol related mechanisms (CDM/JI) applicable when using pyrolysis oil?
4. Why do I want to convert my biomass into pyrolysis oil?
- Intermittent energy source: The production and the application of the bio-oil can take place at different locations and different moments in time.
- Availability: Pyrolysis oil can be stored for long periods of time, and is therefore available when necessary.
- Transportation: Transportation of pyrolysis oil is very convenient. Existing infrastructure can be used for transportation of pyrolysis oil;
- Second generation biofuel: Pyrolysis oil produced from non-food related biomass is a second generation biofuel and therefore does not compete with the food industry.
- Reducing dependency on fossil fuels: Pyrolysis oil can be used in applications where it substitutes for crude oil, doing so it offers a unique way to reduce your dependency on fossil fuels.
- Applications: Pyrolysis oil can easily substitute fossil fuels as oil and gas in existing boiler and turbine applications. Refitting the systems requires limited investments and therefore pyrolysis offers a unique opportunity to make your energy supply sustainable.
5. Can pyrolysis oil substitute for crude oil in conventional refineries?
Yes, proof of principle on upgrading pyrolysis oil for co-feeding in conventional oil refineries has been shown by the Biocoup consortium (www.biocoup.eu) on laboratory scale. BTG-BTL is involved with this consortium through its parent company BTG. More about this HDO route is explained in this brief film by BTG.
Another route to the refinery is co-feeding raw pyrolysis oil to an existing FCC unit in a refinery. Recently Petrobras was at the opening of our Empyro plant to share their findings that it is technically and economically possible to co-process crude pyrolysis oil in existing oil refineries into gasoline and diesel. We are currently promoting this route with several international stakeholders.
6. Is there phase separation of the pyrolysis oil and why does this occur?
At high water contents (>30 wt%)pyrolysis oil is sensitive to phase separation yielding a dark-colored aqueous phase, and a tarry organic phase. Phase separation depends heavily on the type of biomass feedstock and its moisture content. Therefore biomass tests are required for each type of feedstock that has not been tested by BTG-BTL before. There is no phase separation for woody material like pinewood.
However, in case phase separation of pyrolysis oil occurs this is not a problem. Continuous stirring of the oil during storage will make the oil easily deployable without extra treatment. Or a certain amount of water can be removed from the oil by our patented moisture reduction equipment, which can be deliverd with our pyrolysis plant.
7. Is BTG-BTL’s pyrolysis plant commercially available?
8. Is BTG-BTL’s pyrolysis oil commercially available?
Yes. BTG-BTL can provide pyrolysis oil on demand. This will be produced in our own pyrolysis pilot plant. We can supply oil in a range of quantities; from one kilo up to several tonnes. The time of delivery depends on the ordered quantity and required logistics. To order a sample please request a quotation.
9. Is there a quality standard for BTG-BTL pyrolysis oil?
Yes, BTG-BTL delivers high quality pyrolysis oil which fulfills the specifications for solids, water content, flash point, pour point, gross heat of combustion, viscosity, density, sulfur and ash content as prescribed in the ASTM D7544-09 standard.
10. Can BTG-BTL assist with supply chain arrangements?
Yes, BTG-BTL has gained experience in setting up supply chains from biomass sourcing up to pyrolysis oil end-use during commercial scale pyrolysis projects in Malaysia and Hengelo (NL). BTG-BTL underlines the importance of a working supply chain for the success of a pyrolysis project and is therefore pleased to assist you in the set-up.
