There are also two oral sessions for Topic 2.5, “Gasification for synthesis gas production”. The first, 2BO.10, commences at 15:10 on Tuesday and is entitled, “Innovations in Feedstock for Gasification for Synthesis Gas Production”. In this session various feedstocks for gasification for synthesis gas production and factors affecting syngas quality, including sewage sludge gasification for syngas and ash utilisation, are discussed and analysed. Process emissions are also considered, for example through an innovative sampling apparatus for simulation of energy conversion processes. The second Topic 2.5 oral session, 2BO.14, on “Advances in Gasification Processes for Synthesis Gas Production” starts at 16:20 and covers process related factors, for example process design and equipment operating conditions, for production of syngas as well as the cleaning and upgrading possibilities, for example for advanced biofuel production from energy crops and for upgrading of synthesis gas by reforming of recycled methane.
There is one visual/poster session on Tuesday afternoon starting at 14:00, and which combines Topic 2.1, “Production and supply of solid fuels and intermediates”, Topic 2.2 “Biomass and bioliquids combustion for small and medium scale applications” and Topic 2.3 “Biomass combustion in large utilities”. Session 2BV.2 is entitled “Solid Biofuels and Innovative Approaches for Biomass Use in Small to Large Scale Combustion Systems”. The session covers aspects of the energy chains for solid biofuels production, from the characterization of fuel properties, including the development of innovative analytical methods, the analysis of factors affecting the biofuels quality and of fuel properties relevant to logistics and conversion behaviour. The utilisation of new challenging solid fuels and liquid fuels is also addressed. Moreover, new methods to improve process control and combustion performance as well as novel approaches for combustion-based CHP technologies are outlined. This session also deals with measures aimed at increasing systems efficiency, fuel flexibility and reliability.
The oral session (2CO.5) for Topic 2.6 “Anaerobic digestion for biogas and biomethane production” is on “Results from industrial anaerobic digestion plants and related research” and comprises results from large-scale industrial biogas plants, including results from a large-scale wastewater treatment biogas plant and the third monitoring programme of biogas plants in Germany, as well as related research.
There are two visual/poster sessions, both of them in the afternoon. The first session, 2CV.3, from Topic 2.4, “Gasification for Power, CHP and Polygeneration”, and Topic 2.5, “Gasification for synthesis gas production”, starts at 15:10. This session on “Innovations in Feedstock and Modeling Towards Enhanced Implementation of Gasification” focuses on various gasification feedstocks, the influence on different gasification agents as well as modelling of process conditions. In addition, gas cleaning and upgrading of syngas are discussed as well as techno-economical aspects. The session also addresses both integrated gasification and CHP systems, including a transportable biomass gasification unit for agricultural residues, fuel characterization and emissions in both experimental and modelling projects.
The second visual/poster session is for Topic 2.6, “Anaerobic digestion for biogas and biomethane production”. The session (2CV.5), “Anaerobic Digestion optimization for biogas and biomethane production “, starts at 16:20 and covers a wide range of biomass substrates for biogas and hydrogen production, biomass pretreatment methods, co-digestion, gas cleaning and technologies for biogas upgrading to biomethane for pipeline injection. The session also deals with biogas process performance optimization, enhanced methane yield as a function of biomass substrate, hydrogen production and integration of anaerobic digestion with other process wastes and residues.
There are two oral sessions for Topic 2.6, “Anaerobic digestion for biogas and biomethane production”. Starting at 09:00 is session 2DO.1 on “Biogas Cleaning and Use in Local Communities”.
