Sustainable Production of Carbon Monoxide by Direct Current Gas Discharge - Bok av Stephan Renninger - Häftad

Sustainable Production of Carbon Monoxide by Direct Current Gas Discharge - Bok av Stephan Renninger - Häftad

Carbon is the centerpiece in most chemicals and fuels. In light of climate change non-fossil paths to supply it are necessary. Carbon monoxide is a key molecule for carbon utilization. Forming it into hydrocarbons is an established process. Gliding arc plasma sources can produce it by ¿warm¿ plasma, which has high reactivity and space-time yield at low energy input.The first part of this work deals with the construction and characterization of two gliding arc plasma sources and driver circuits...

Experimental analysis of fast reactions in gas-liquid flows (Band 3) - Bok av Jens Timmermann - Häftad

Experimental analysis of fast reactions in gas-liquid flows (Band 3) - Bok av Jens Timmermann - Häftad

BeschreibungGases have to be specifically mixed with a continuous liquid phase to perform a reaction with high yield and selectivity. The time scales of mixing are determined by the transport processes in the boundary layer close to the phase boundary and by bubble swarm turbulence. For clarification of the local mass transfer in bubbly flows, an experimental setup is developed and successfully used to investigate single rectilinear (spherical), helical (ellipsoid) and irregular rising bubbles with..

Fast Pyrolysis of Technical Lignins in a Circulating Fluidized Bed Reactor - Bok av Miika Franck - Häftad

Fast Pyrolysis of Technical Lignins in a Circulating Fluidized Bed Reactor - Bok av Miika Franck - Häftad

In search of an alternative for chemicals and energy from fossil fuels, lignin pyrolysis is experimentally investigated in a circulating fluidized bed. Deviation in pyrolysis behavior of a softwood Kraft lignin and a wheat straw hydrolysis lignin is analyzed by means of char morphology as well as overall yield and composition determination for gas, oil, and char. The influence of catalytically active mineral matter in lignin on the product distribution is investigated. Progressively, the fluidized..

Leading People into a Better Future through Information System Interaction and Engagement - Bok av Tim-Benjamin Lembcke - Häftad

Leading People into a Better Future through Information System Interaction and Engagement - Bok av Tim-Benjamin Lembcke - Häftad

Climate change has become one of the most significant challenges humanity faces. Asgreenhouse gas emissions continue to rise, not only will natural disasters strike considerablymore frequently and severely, but whole swaths of land will become uninhabitableand infertile as farmland. It is apparent that long-term approaches like reaching net-zerowith new technologies are important, but so are short-term measures to avoid tippingpoints and passing points of no return. The transport sector accounts..

Experimental Investigation of a semi-industrial Carbonate Looping Process for scale-up - Bok av Jochen Bernd Ludwig Hilz - Häftad

Experimental Investigation of a semi-industrial Carbonate Looping Process for scale-up - Bok av Jochen Bernd Ludwig Hilz - Häftad

An efficient post-combustion capture technology is the carbonate looping (CaL) process reducing the amount of CO2 released by fossil fuelled power and industrial plants (CCS/U). Limestone based sorbents are circulated between two interconnected circulating fluidized bed (CFB) reactors. In a first reactor, the carbonator, the main part of CO2 contained in the flue gas of an upstream emission source is absorbed by CaO. The CO2 is released and the sorbent regenerated under oxy-firing conditions in a..
