Pyrolysis of olive stone for energy purposes

Pyrolysis of biomass is a. promising teclmology for the production of distributed and renewable energy on small and micro-scale since it produces a. gas with relatively high calorific value, which can be burned in an internal combustion engine or in a microturbine; pyrolysis also generates byproducts (char and tar) which can. be used to provide energy to the process or for cogeneration purposes. This research is aimed at the exploitation of waste from agricultural production processes, in particular olive mill wastes whose management has critical environmental and disposal costs; the yields of pyrogas, tar and char obtained from the pyrolysis of olive stone in a batch reactor was measured. Pyrogas produced is sampled through a line for the sampling of condensable substances in accordance with. existing regulations, CEN/TS 15439, and once purified from water vapor and tars is analyzed with micro-GC. The data collected is used to perform mass and energy balances and to determine the content of tars and the Low Heating Value (LHV) of the gas produced. (C) 2015 The Authors.
