The impact of sorbent geometry on the sulphur adsorption under supercritical water conditions: a numerical study
Christian Ludwig, Andrea Testino
A numerical model to show the impact of the adsorption bed geometry on the desulfurization process of wet biomass under supercritical water (SCW) gasification process has been developed. Three different geometries, straight channels (pipe), sharp-edged cha ...
Springer Heidelberg2017Multi-objective optimization of a sugarcane biorefinery for integrated ethanol and methanol production
François Maréchal, Adriano Viana Ensinas, Emanuela Peduzzi, Priscilla Caliandro, Sandro Onorati
The present study evaluates a sugarcane biorefinery producing ethanol through juice fermentation and methanol via gasification of sugarcane lignocellulosic residues and liquid fuel synthesis. Two technologies of gasification named entrained flow and circul ...
2017Extraction of carotenoids from Chlorella vulgaris using green solvents and syngas production from residual biomass
Christof Holliger, Christian Ludwig, Shivom Sharma, Jean-Paul Schwitzguebel, Dominik Refardt
A combined process for carotenoids extraction and efficient bioenergy recovery from the wet microalgae biomass is proposed. High added-value products could thus be extracted prior a hydrothermal gasification of the algal biomass into synthetic natural gas. ...
2017Adsorption of thiophene by activated carbon: A global sensitivity analysis
The removal of sulfur compounds in biomass gasification processes is crucial to protect downstream equipment. While conventional sorbent materials can retain H2S, many fail to capture heterocyclic sulfur compounds such as thiophene (C4H4S). This work explo ...
Elsevier Sci Ltd2017Online Detection of Selenium and Its Retention in Reducing Gasification Atmosphere
Christian Ludwig, Andrea Testino, Mohamed Tarik, Adrian Hess
The emission of selenium from coal gasification processes can cause harm to the environment and downstream equipment. With upcoming legislation, reliable detection as well as control of such gas species become crucial. This study therefore addresses the de ...
American Chemical Society2016On-line liquid quench sampling and UV–Vis spectroscopy for tar measurements in wood gasification process gases
Christian Ludwig, Rudolf Paul Wilhelm Jozef Struis
In biomass gasification processes, the formation and handling of tars are of major concern. Robust and versatile analytical tools are needed to on-line monitor tar compound concentrations in process gases from lab- to industrial scale. This study addresses ...
Elsevier2016Optimal design methods applied to solar-assisted hydrothermal gasification plants
The gasification of highly watered waste residues may help to reduce fossil fuels consumption, as well as emissions, all the while improving efficiency. The integration of supercritical gasification with solar energy may improve the performances of both ne ...
EPFL2016On the efficiency, exergy costs and CO 2 emission cost allocation for an integrated syngas and ammonia production plant
This paper presents an exergy and environmental assessment of a 1000 metric t/day ammonia production plant based on the steam methane reforming (SMR) process, including the syngas production, purification (CO2 capture) and compression units, as well as the ...
2016Surface oxidation effect on the electrical behaviour of Bi2Te2Se nanoplatelets
Klaus Kern, Marko Burghard, Pascal Gehring
Charge transport in topological insulators is notably influenced by moisture and air in the surrounding environment. At present, however, little is known about the detailed composition of the oxidized surface and its impact on the electrical characteristic ...
Iop Publishing Ltd2016Structural Modification of Ni/gamma-Al2O3 with Boron for Enhanced Carbon Resistance during CO Methanation
Carbon deposition during CO methanation from biomass-derived gas is a significant challenge in terms of catalyst lifetime. It results from the severe reaction conditions imposed by the presence of unsaturated hydrocarbons in the gasified feedstock. This wo ...
