Head of the research group "Phosphorus Recycling"

 

Research Interests

The Group is investigating the transformation of phosphorus during the high temperature processing of wastes.

My research activities up to now are focused on:

  • operation / improvement / characterization of fluidized bed systems combining various field of science i. e. hydrodynamics, thermodynamics and kinetics
  • planning and executing experimental work as well as validating and analysing the results
  • proposing and validating simple reactor models useful for process upscaling works
  • studying the chemical and mechanical behaviour of Ca based sorbents in fluidized bed combustion conditions
  • studying the chemical and mechanical behaviour of sewage sludge during thermal treatment with focus on phosphorus recovery
  • process modelling, simulation and evaluation of the high temperature fluidized bed system for phosphorus recovery
