Slow pyrolysis of wood
Webbof pyrolysis: fast pyrolysis with a typical maximum bio-oil yield of around 60-80 wt. % at very short residence times, convectional pyrolysis with equal yields of product at middle residence time (minutes), and as the last, slow pyrolysis with a maximum solid yield of around 60-80 wt. % at very long residence time (hours) [1]. WebbThe thermochemic conversion of biomass (pyrolysis, gasification, combustion) represents the most promising technique for energy production. In this context fits the application of the process of slow pyrolysis of biomass in a rotary kiln reactor with an integrated gas burner of small size for a continuous production of syngas.
