Welcome to the Biomass conversion technologies database which you can access underneath!
Through the underneath table users can access the database on lignocellulosic biomass conversion technologies characteristics (click on the number in last column). The data included in this database are feeding the Bio2Match, the BeWhere and the LocaGIStics tools all accessible via the main menu in this toolset under 'Tools'. accessible under the ‘Tool' tab in the main menu above. In the process of creating the database it was ensured to take up the technologies relevant for producing the products described in the product market combinations in WP7 and that were the basis for assessing 2020 and 2030 biomass demand and consumption levels (see Tab 'General data' ---> 'Biomass demand'. For heat, power and fuels, several technologies are available in the database, while for other bio-based products (especially through the sugar platform) some but fewer conversion technologies are included. This is a representation of the technology readiness levels and the current and expected market situation for these products.
In the underneath table an overview is provided of all technologies included in the conversion technologies database. To access the detailed technology characterisation sheets in de database click on the technology number in the last column of the table. To return to the overview table again click on the return arrow.
The technologies covered can be classified in 6 main categories: treatment in subcritical water, syngas platform, gasification technologies, fast pyrolysis, direct combustion of solid biomass, chemical pretreatment, biochemical hydrolisis and fermentation and anearobic digestion. For a further description of the biomass conversion technologies database please consult D2.3. The method developed in S2BIOM for minimal biomass quality requirement for each biomass conversion technology is described in D2.1 and D2.2.

| Year of first implementation | 2014 |
| Estimated number of systems in operation | 0 |
| Main operating principle: |
| Producer gas production: The gasification section consists of two fluidized-bed reactors: gasifier and combustor. Biomass is fed into gasification chamber, and converted to nitrogen-free fuel gas (producer gas) and char using steam. The char is burnt in air in the combustion chamber, heating bed particles, bed material is fed back into the gasification chamber providing heat for gasification reactions. Producer gas is cooled and filtered and tars are removed in an oil scrubber. Partially cleaned gas is led into final gas cleaning and conditioning unit after which it is pressurised and led into methanation. //// SNG production: Methanation takes place either within a fluidized bed reactor that has been developed specifically for the biomass-to-SNG process by PSI and CTU from Switzerland, or in existing fixed bed methanation technology. Depending on the concept, CO2 removal can take place prior, or downstream methanation step using, a.o., amine scrubbing. Further conditioning to bio-SNG includes at least a gas drying step. |
