Production and characterization of bio-oils from fast pyrolysis of tobacco processing wastes in an ablative reactor under vacuum.

Application of advanced pyrolysis processes to agricultural waste for liquid production is gaining great attention, especially when it is applied to an economic crop like tobacco. In this work, tobacco residues were pyrolyzed in an ablative reactor under vacuum. The maximum bio-oil yield of 55% w/w...
