Biomass To Liquids : Thermo-Economic Analysis and Multi-Objective Optimisation

Emanuela Peduzzi

Biomass is the major source of renewable carbon which can be used to substitute fossil carbon in fuels and chemical products. This thesis addresses the modelling, design and thermoeconomic evaluation and optimisation of processes converting Biomass to Liqu ...

Sulfur containing organic compounds in the raw producer gas of wood and grass gasification

Christian Ludwig, Tilman J. Schildhauer

The detailed description of gas streams in biomass gasification plants is necessary for the correct design and operation of these units. Sulfur containing compounds are usually present in biomass gasification gas, since sulfur is typically found in the fee ...

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 ...

Development and Application of Devices for Online Trace Element Analysis of Thermal Process Gases from Woody Feedstocks

Marco Wellinger

When using natural or waste wood in thermo-chemical conversion processes, the presence of a number of heteroatoms (e.g. sulfur, chlorine, potassium and sodium or heavy metals) may hinder the processes themselves as well as pose a threat to equipment and/or ...

Gasification of Hay in a Bench Scale Fluidised Bed Reactor with Emphasis on the Suitability for Gas Turbines

Christian Ludwig, Marco Wellinger

Thermal gasification of pasture plants (hay) is so far considered as difficult mainly due to the high amount of inorganics (ash, alkalis). Under certain circumstances it could be an additional resource for power production. There has been some experiments ...

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 ...

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 ...

Increasing Conversion Efficiency in Fuel Ethanol Production from Lignocellulosic Biomass by Polygeneration - and a Paradoxon between Energy and Exergy in Process Integration

François Maréchal, Martin Gassner

In the public and scientific debate on biofuels, ethanol from lignocellulosic biomass is generally the most popular alternative that may allow for a sustainable production. Compared to thermochemical processing of biomass which assures a complete conversio ...
