By Steffen Heidenreich, Michael Müller, Pier Ugo Foscolo

Advanced Biomass Gasification: New recommendations for potency bring up and Product Flexibility presents a radical assessment on new innovations in biomass gasification and consolidated info on advances for technique integration and mix, that may another way merely be won through interpreting a excessive variety of magazine publications.

Heidenreich, Müller and Foscolo, hugely revered specialists during this box, commence their exploration with the compact distinct reactor, gasification and pyrolysis, gasification and combustion, and catalysts and membranes. The authors then study biomass pre-treatment procedures, considering the strength stability of the final conversion strategy, and investigate oxygen-steam gasification and options for air separation, together with new recommendations for integration of O2-membranes into the gasifier. numerous polygeneration innovations are coated, together with mixed warmth and tool (CHP) construction with artificial traditional fuel (SNG), biofuels and hydrogen, and new state of the art ideas, resembling plasma gasification, supercritical water gasification, and catalytic gasification, which permits for insights at the destiny technological outlook of the area.

This ebook is then a helpful source for and academia-based researchers, in addition to graduate scholars within the power and chemical sectors with curiosity in biomass gasification, specifically in parts of energy engineering, bioenergy, chemical engineering, and catalysis.

  • Explores cutting-edge applied sciences that let for larger potency and suppleness in gasification, together with technique integration, mix, and polygeneration strategies
  • Consolidates info that was once, up formerly, scattered between numerous assets, together with magazine articles
  • Provides a beneficial source for and academia-based researchers, in addition to graduate scholars within the power and chemical sectors with curiosity in biomass gasification, specifically in parts of strength engineering, bioenergy, chemical engineering, and catalysis

7 CONCLUSIONS AND OUTLOOK ON FURTHER INTEGRATION OPTIONS Besides the deep involvement of the authors of this book in the invention and development of the UNIQUE gasifier concept, which is one reason that this concept has been selected to be described in some detail within the book, it has also been selected since it is a nice example of the benefit and challenges of process integration. By integration of process steps, the chance for a simple optimization of the single steps is replaced by a more complex adjustment of the different steps with the need to take into account the influence and dependence of the different steps on each other, respectively.

An alkali silicate melt can be formed on top of the SiO2 layer which increases the water vapor diffusion through the SiO2 layer. Thus, the oxidation of the silicon carbide material beneath the SiO2 layer is enhanced and causes formation of gaseous CO. This leads to the expansion and dissolution of silicon carbide material. The investigations of Schaafhausen et al. showed that even if silicon carbide filter elements have been used successfully at 800°C in biomass gasification environment for short-term operations of some 10 h as shown above, Advanced Process Integration Chapter | 4 29 silicon carbide filter elements are not the right choice for long-term operation in the freeboard of a fluidized bed biomass gasifier where temperatures significantly above 800°C can occur.
