Catalysts for High Temperature Gas Cleaning in the Production of Synthetic Natural Gas from Biomass

Bio synthetic natural gas (Bio-SNG) is being proposed as an alternative to the natural gas of fossil origin (NG) [1]. Bio-SNG consists mainly of CH4 (at least 95%mol), has a high heating value (e.g. 10 kWh/m3N), and respects the quality standards of the NG ...

Transmission of Alkali Aerosols through Sampling Systems

Christian Ludwig, Tilman J. Schildhauer

In biomass gasification, particles such as condensed alkali salts pose a threat on equipment. Due to high loads of condensable tars in the gases, sampling of these particles to liquids and subsequent analysis of the liquid is frequently the method of choic ...

Sampling and Online Analysis of Alkalis in Thermal Process Gases with a Novel Surface Ionization Detector

Christian Ludwig, Marco Wellinger

When using biomass or waste as a feedstock for power production, alkalis are a major concern because of their negative effects on equipment. To investigate the release behavior of alkalis and the effectiveness of countermeasures, it is indispensable to qua ...

Prediction of the entrained liquid fraction in vertical annular gas–liquid two-phase flow

John Richard Thome, Andrea Cioncolini

The study considers the prediction of the entrained liquid fraction in adiabatic gas-liquid annular two-phase flow in vertical pipes. Nine empirical correlations have been tested against an experimental data bank drawn together in this study containing 150 ...

Gas-assisted focused electron beam and ion beam processing and fabrication

Patrik Willi Hoffmann, Ivo Utke

Beams of electrons and ions are now fairly routinely focused to dimensions in the nanometer range. Since the beams can be used to locally alter material at the point where they are incident on a surface, they represent direct nanofabrication tools. The aut ...

How much room is left for European gas incumbents?

Bastian Wolfgang Schwark

In the context of the liberalization of the European natural gas market former monopolists face a challenge to react to market opening by realigning their strategies. Three major groups of companies can be identified that are capable to influence the Europ ...
