Pyrolytic products from tannery wastes

Pyrolytic products evolved from the thermal degradation of tannery wastes have been studied using a Pyroprobe 1000 with a secondary reactor and a small furnace. Main primary and secondary products have been analyzed as a function of the operating temperature, using the Pyroprobe 1000 with the secondary reactor at low temperatures (primary reaction in the Pyroprobe 1000) or at high temperatures (primary reaction in the Pyroprobe 1000 and secondary reaction in the secondary reactor). In addition, some runs were carried out in a small furnace to consider the minor products evolved from the primary decomposition and from the primary decomposition + secondary tar cracking.
