Valuable (by-)products of gasification
Workshop organized by IEA Bioenergy Task 33 (gasification)
Location: Living Hotel Kaiser Franz Joseph, conference room nr. 3+4, Sieveringer Str. 4, 1190 Vienna, Austria
Online participation possible
The main product of biomass gasification process is producer gas, which could be converted into synthesis gas after cleaning and conditioning . The syngas contains mainly CO and H2; this mixture is beneficial for further processing, e.g. for production of biofuels and/or biochemicals.
The figure below shows the syngas utilization pathways. Dry solid biomass is converted into syngas through a gasification process, followed by cleaning and conditioning steps.
The cleaning process is less demanding if the syngas is used for combined heat and power production, co-firing or production of high temperature heat.
For the synthesis to biofuels and/or biochemicals, more precise cleaning and conditioning processes are necessary. In this way gaseous bio-products such as synthetic natural gas (SNG), hydrogen or ammonia can be produced. Moreover, liquids biofuels and biochemicals, such as Fischer-Tropsch (FT) liquids (e.g. biodiesel, biokerosene, biopetrol), mixed alcohols or methanol/DME can be produced.
Biochar is a valuable by-product of gasification, which could be utilized in many ways, e.g. for soil improvement, as an additive to animal feed, in industrial processes as filtration medium, etc. It could also be employed as a carbon storage in soils, thereby positively contributing to the overall greenhouse gas (GHG) balance.
Combined heat and power (CHP) production through biomass gasification is already matured technology, with more than 1 700 operational units in Europe. Biomass gasification is also employed in industrial processes to transition away from fossil fuels and reach better GHG balances. The produced gas is co-fired in the boilers and the heat is used within the industrial process.
In recent years, development of units for SNG or FT liquids, as well as methanol and mixed alcohols can be observed in markets. It is clear that the gasification technology will play an important role in a fossil-free future.
The actual developments in the field of gasification (by-)products will be presented in the workshop. On 20 October onsite participants can follow a site visit to the project “Waste-2-Value”.
