Advanced technologies for power, heating and bio-based products at EUBCE 2016

The plenary sessions at the European Biomass Conference always feature major innovations and technological developments in the areas of biomass heating and power, biogas, bio fuels and biorefinery plants. Here are six presentations which will be given at the upcoming EUBCE 2016 in Amsterdam, with an emphasis is on reducing emissions from small scale boilers, large scale gasification, innovative pyrolysis processes, bio-based products from pulp mills and regional integration of biorefineries.

Ultra low emission boiler: a sustainable technology for pellet and wood chip fuels

A novel small-scale biomass boiler concept based on an extremely air-staged burner has been developed. Based on the data and experiences gained during the test stand and field tests a comprehensive technological assessment of the ultra-low emission boiler technology has been done. The new ultra-low emission boiler technology can achieve almost zero CO, OGC and dust emissions and also reduces NOx emissions in comparison to the present state-of-the-art by the application of primary measures only. Another very relevant achievement is the reduction of total suspended particles in the flue gas.

Success stories in large scale biomass gasification to replace fossil fuels

Two examples of large scale operating CFB-gasification plants will be presented.The first example is a concept where in a high efficiency coal fired supercritical PC boiler is substituted by producer gas coming from a CFB gasifier. The fuel fed to gasifier is a mixture of various kind of biomass, like saw dust, forest residues, bark, shredded stumps, uncontaminated waste wood, etc. By this concept the operability of the existing power plant is not affected and the high steam parameters could be kept without problems of corrosion and fouling.The second successful CFB gasification project is the Kymijärvi II plant in Lahti, were SRF (solid recovered fuels) with a biogenic part of 50% is gasified to produce a gas that is then cleaned and combusted in a dedicated gas fired boiler at high steam parameters. Using this concept, efficiency from waste as a fuel can be achieved.

Autothermal pyrolysis : an innovative concept aimed at process commercialization

Most pyrolysis commercialization efforts focus on stabilizing bio-oil as fuel oil substitute or hydro processing it into gasoline and diesel-range hydrocarbons. Auto thermal pyrolysis simplifies thermal management by providing the enthalpy for pyrolysis through partial combustion reactions. Acid pretreatment of biomass passivates undesirable catalytic activity of alkali and alkaline earth metals in biomass, which otherwise reduces pyrolysis yields of soluble carbohydrate from holocellulose. A bio-oil recovery system based on fractionating pyrolysis vapors makes possible the recovery of separate streams of solubilized carbohydrate, phenolic oil, light oxygenates, and acetic acid.

Hydrothermal lignin liquefaction: A chemical degradation mechanism for increased yield and molecular selectivity

The focus of the work is to clarify the chemical degradation mechanism under hydrothermal conditions to liquefy lignin to high functional molecules and to increase the yield and selectivity towards bi functional molecules like catechols. The combination of fast hydrolysis, thermal degradation reactions, and hydrogenation drives the hydrothermal liquefaction and gives the possibility to narrow down the product spectrum in comparison to other “dry” methods, towards a higher yield of e.g. catechols.

Biorefinery at Stora Enso: from pulp mills to renewable materials

While Stora Enso was traditionally a pulp and paper business, its new business platform is based on biomass and focused on second-generation biochemicals and biomaterials, using non-food, non-GMO competing feedstock. It opened a Biomaterials division in 2012 and has acquired a technology with a bio refinery concept which overcomes cost and purity issues. The bio refinery is a major shift in Stora Enso’s evolution and the company is keen to produce intermediates to substitute petro-based products. Transforming biomass resources into raw materials which can be further refined is key to integrating production processes into a bio refinery model which addresses markets across value chains. By focusing on innovative technologies, which use local biomass, the company is reducing energy and materials imports and helping to create jobs in farming communities.

Novamont biorefinery: promoting sustainable development with territorial integration

As a consequence of energy-related and environmental problems, renewable raw materials such as vegetable oils, starch from corn and potatoes, cellulose from straw and wood, lignin and amino acids are becoming increasingly important as industrial feed stocks. As an example of prudent use of local resources, starting from biodegradable plastics taken as a case study, this presentation will introduce the concept of a bio-refinery integrated into a local territory, that Novamont is implementing with determination since many years.
