11. Hydrogen production from fossil fuels with carbon dioxide capture, using chemical-looping technologies
Abstract : Carbon capture and storage have been receiving increasing interest lately, mainly as an option to reduce CO2 emissions from the power sector. The concept could be adapted for production of H2 as well, which would provide a carbon free energy carrier that could be used for example as transportation fuel. READ MORE

12. Hydrogen Production by Integration of Fluidized Bed Heat Exchanger in Steam Reforming of Natural Gas
Abstract : The possibility to integrate fluidized beds as heat sources for steam reforming in hydrogen production plants is examined in this work. Sites with large-scale production and consumption of hydrogen such as refineries are considered as especially interesting. READ MORE

13. Novel Metal Oxide Bed Materials for Efficient Solid Fuel Gasification and Gas Clean-up in Fluidized Beds
Abstract : In this work the utilization of some novel metal oxide bed materials in dual-fluidized bed gasification systems has been investigated. For this purpose, metal oxide based bed materials can be 1) directly utilized in the dual fluidized bed gasifier (DFB) or in the Chemical Looping Combustion (CLC) process in order to achieve higher gasification rates, or 2) employed in downstream hot gas conditioning processes, e.

14. Internal Tar/CH4 Reforming in Biomass Dual Fluidised Bed Gasifiers towards Fuel Synthesis
Abstract : Production of high-quality syngas from biomass gasification in a dual fluidised bed gasifier (DFBG) has made a significant progress in R&D and Technology demonstration. An S&M scale bio-automotive fuel plant close to the feedstock resources is preferable as biomass feedstock is widely sparse and has relatively low density, low heating value and high moisture content.

15. Energy Efficient Processes for the Production of Gaseous Biofuels - Reforming and Gas Upgrading
Abstract : Replacing fossil fuels with biofuels is one way of reducing the emission of greenhouse gases into the atmosphere, thus decreasing our impact on the global climate. For this to be a viable option, several production routes are needed, as no single option can fully replace fossil fuels. READ MORE
