摘要

Glycerol is an interesting compound with a medium heating value that can produce good quantities ofrnhydrogen, when converted through pyrolysis (even equal to 50%v at 800℃). Glycerol is a waste of biodieselrnproduction. In Europe about 1.2 Mm~3/y of waste glycerol are available. In this work the energy use of glycerol will bernanalyzed by an economical point of view, focusing on the production of pellet made of 10%w glycerol and 90%wrnsaw dust and its conversion through pyrolysis, to produce heat and electricity in a rotary kiln plant. This study will bernbased on data retrieved from two experimental campaigns: the first performed at University of Perugia, BiomassrnResearch Centre, and the second at Bioenergy 2020+ and Graz University of Technology. The second experimentalrncampaign was performed in the framework of the European project BRISK and was used also to check the reliabilityrnof the first. The purpose of the work is to determine an optimal way to convert in energy waste glycerol by anrneconomical point of view and to trace new frontiers for research in the field. While pyrolysis of glycerol is an alreadyrnknown technology, the use of pellets made from a mixture of biomass and glycerol could be also an interestingrnalternative. When coupled to a transesterification plant an Integrated Pyrolysis Regenerated Plant fed with pelletsrnmade mixing 90% sawdust and 10% glycerol, would cover the entire energy consumption and have a payback periodrnof about 5.7 years.
