Abstract:
Glycerol is an interesting compound with a medium heating value that can produce good quantities of hydrogen, when converted through pyrolysis (even equal to 50%v at 800°C). Glycerol is a waste of biodiesel production. In Europe about 1.2 Mm3/y of waste glycerol are available. In this work the energy use of glycerol will be analyzed by an economical point of view, focusing on the production of pellet made of 10%w glycerol and 90%w saw dust and its conversion through pyrolysis, to produce heat and electricity in a rotary kiln plant. This study will be based on data retrieved from two experimental campaigns: the first performed at University of Perugia, Biomass Research Centre, and the second at Bioenergy 2020+ and Graz University of Technology. The second experimental campaign was performed in the framework of the European project BRISK and was used also to check the reliability of the first. The purpose of the work is to determine an optimal way to convert in energy waste glycerol by an economical point of view and to trace new frontiers for research in the field. While pyrolysis of glycerol is an already known technology, the use of pellets made from a mixture of biomass and glycerol could be also an interesting alternative. When coupled to a transesterification plant an Integrated Pyrolysis Regenerated Plant fed with pellets made mixing 90% sawdust and 10% glycerol, would cover the entire energy consumption and have a payback period of about 5.7 years.
