Fuel reactor modelling for chemical looping combustion: From micro-scale to macro-scale

Microbiology for chemical engineers – from macro to micro scale

Recent developments in microbial techniques (such as PCR, GE, FISH) have allowed researchers to detect, identify and quantify microorganisms without the limitation of culture-dependent methods. This has given both engineers and scientists a more fundamental understanding about systems containing microorganisms. These techniques can be used to monitor bacteria in wastewater treatment systems, so...

Concentration Slip and Its Impact on Heterogeneous Combustion in a Micro Scale Chemical Reactor

The rarefied gas effect on concentration slip and on heterogeneous combustion in microscale chemical reactors was investigated. First, a concentration slip model to describe the rarefied gas effect on the species transport in microscale chemical reactors was derived from the approximate solution of the Boltzmann equation. Second, the model was verified using the direct Monte-Carlo method for th...

Dynamic Model of Single-reactor Chemical Looping Combustion

The paper presents a simplified model of chemical looping combustion in a fixed bed reactor under isothermal condition. Both reduction and regeneration phases of the oxygen carrier are modeled in the single reactor model under the hypothesis of discontinuous feed and simplified reaction kinetics. This model is meant to be the simplest possible formulation for a description that incorporates all...
