Process design for a large-scale BioSyngas production plant for the economic and ecological optimum co-production of chemicals and secondary energy carriers from biomass

Biomass is heading for a great future as renewable energy source. It not only is available in large quantities but it also is the only renewable energy source that is suitable for the sustainable production of (generally carbon containing) transportation fuels and chemicals. Chemicals, transportation fuels, gaseous energy carriers, power and/or heat, that are currently being produced by fossil primary energy carriers, are expected to be produced from biomass to a large extent in the near future within the so-called biorefinery concept.
Due to the very wide application framework for biomass, the biomass demand in the future is expected to be enormously, which will result in increased raw biomass costs. The biomass available, therefore, has to be converted with high efficiency into a variety of products, maximizing overall process economics, and minimizing the overall negative ecological side effects. A promising option to achieve this is to convert it on a large-scale into BioSyngas via gasification and subsequently to co-produce a variety of marketable products from biomass. After clean-up, conditioning, and CO2-removal, the BioSyngas can be used to synthesize a variety of marketable products ? chemicals (methanol, BTX, olefins, phenols, naphthalene, cresylic acid, fertilizers, ?), transportation fuels (FT-diesel, mixed alcohols, H2, ...), gaseous energy carriers (SNG, H2), power and/or heat ? from biomass. Several of these products can also already be obtained as intermediate co-products during the clean-up stages.
The main objective of this paper is to determine the technical and economic feasibility of a biorefinery system which targets to an efficient co-generation of chemicals, transportation fuels and secondary energy carriers from biomass. The study is limited to a large-scale production, as this is required to make a significant contribution to the European renewable energy targets (e.g. 10% substitution of renewable energy carriers by 2020).
